# How to Pass the Florida Dental Hygiene Laws and Rules Exam in 2026

The Florida Dental Hygiene Laws and Rules Exam (FHLR) sits on every pathway to a Florida dental hygiene license — new graduates, hygienists relocating from other states, and internationally trained dentists entering through Florida's hygiene statute alike. It is a separate exam from the dentist FDLR, and much of the free material about it online is undated or quotes superseded rule text. This guide carries the current facts: the exact format under rule 64B5-2.0135, F.A.C., as amended effective June 1, 2026, who must take it, the two-track registration process and its clocks, the 3% Chapter 456 cap and where the other 97% of the questions live, the supervision-and-scope map the exam keeps returning to, the traps that fail relocating hygienists, a five-part study plan, exam-day logistics at Prometric, and the full-fee retake economics. Every material rule traces to the primary sources listed below or linked inline.

Last verified 2026-08-24. Published by Dentovio, an independent publisher — not the Florida Board of Dentistry, ADEX, CDCA, Prometric, or any government agency. This guide summarizes publicly available Florida dental law as of the date above; laws change, so confirm current requirements with the Florida Board of Dentistry or a licensed healthcare attorney before acting.

## Key facts

- **Format:** Up to 64 multiple-choice items — Including up to 5 unscored field-test items. Multiple choice, computer-based.
- **Time:** 90 minutes — Roughly 84 seconds per item at the full 64-item count.
- **Passing mark:** 75% or higher — Set by rule 64B5-2.0135, F.A.C. Results are pass/fail only — no numeric breakdown.
- **Fee:** $105 per attempt — Initial sitting and each retake cost the same full fee. Registration credits expire 2 years from payment.
- **Delivery:** Prometric test centers, closed book — Administered by ADEX/CDCA under contract with the Florida Department of Health. Reference materials are conduct violations.
- **Results:** Provisional pass/fail on screen; official in 2-3 business days — A provisional result appears on screen at completion; the official result posts to your candidate portal. No score report beyond pass/fail is published.
- **Scope:** Ch. 466, F.S. + Division 64B5, F.A.C., with Ch. 456 capped at 3% — Rule 64B5-2.0135(2)(c) caps Chapter 456 at 3% — the only content weight Florida publishes for this exam.
- **Pass rate:** None published — Florida publishes no pass rate for the FHLR. Judge difficulty from the structure, not from unsourced figures.
- **Who sits it:** Every hygiene licensure pathway — no general reciprocity — Examination, MOBILE endorsement, and the internationally-trained-dentist pathway all include it. Hygienists are Florida's larger initial-licensure cohort (Florida MQA annual report, FY 2024-25).
- **Study pacing:** Set by your diagnostic — Florida publishes no typical preparation duration or outcome-by-study-time data.

## The FHLR, exactly — and the stale claims to purge before you study
The **Florida Dental Hygiene Laws and Rules Exam (FHLR)** is a written examination on Florida dental hygiene law required on every pathway to a Florida dental hygiene license. It runs under [rule 64B5-2.0135, F.A.C.](https://www.flrules.org/gateway/ruleNo.asp?id=64B5-2.0135), is administered by ADEX/CDCA under contract with the Florida Department of Health, and is delivered at Prometric test centers. Candidates search for it under several names — the Florida dental hygiene **jurisprudence** exam, the "Florida laws and rules test," the "Florida law exam" — but it is one examination, and generic "jurisprudence exam" results often describe **other states'** exams entirely.

| | **FHLR — Florida dental hygiene candidates** |
| --- | --- |
| Items | Up to **64** multiple-choice, including up to 5 unscored field-test items |
| Time | **90 minutes** |
| Pass mark | **75% or higher** |
| Fee | **$105** — initial sitting and each retake alike |
| Delivery | Computer-based at Prometric, **closed book** |
| Results | **Pass/fail only** — provisional on screen at completion; official posted in 2-3 business days |
| Governing rule | 64B5-2.0135, F.A.C., current version effective **June 1, 2026** |
| Scope | Ch. 466, F.S. + Division 64B5, F.A.C., with **Ch. 456 capped at 3%** |

All of the above comes from the [ADEX/CDCA vendor page](https://adextesting.org/fl-laws-rules/), the 2026 ADEX Candidate Guide, and the current rule text — the documents that control this exam.

**It is not the dentist exam.** The dentist cohort sits the FDLR under a different rule (64B5-2.013), with a different item count (up to 67) and a different fee ($135). The two exams draw on the same body of Florida law with different emphasis, so prep written for dentist candidates misweights a hygienist's study time — the [dentist guide](/guide/florida-dental-laws-rules-exam/how-to-pass) covers that exam.

**Four stale claims circulate about this exam, and each is checkable:**

1. **"Chapter 64B27 (dental laboratories) is tested."** It appeared only in the retired 2019 candidate booklet. The live scope is Chapter 456 (capped at 3%), Chapter 466, and Division 64B5 — nothing else. Details in our dated note on [the current scope](/what-changed/florida-laws-rules-scope-64b27-2026).
2. **"The exam must fit inside the ADEX 18-month window."** The 18-month completion window in rule 64B5-2.0135(3) attaches to the ADEX **clinical** examination parts; the 2026 ADEX Candidate Guide lists the Laws and Rules exam as a standalone computer-based exam. The only clock on it is that **registration credits expire 2 years from payment**. Rule walkthrough in [our 18-month-window note](/what-changed/florida-18-month-window-laws-rules).
3. **"Any Florida laws-and-rules deck will do."** Undated crowd-sourced decks predate the exam rule's **June 1, 2026** amendment and the December 2024 MOBILE endorsement rule, and most were written for the dentist exam's weighting anyway. A deck that cannot tell you its own date cannot tell you which rule version it quotes.
4. **"Here's the pass rate."** **Florida publishes no pass rate for this exam** — not the Board, not the department, not the vendor. Results are pass/fail only, so no score distributions exist publicly either. Any percentage you see elsewhere is unsourced. What is knowable is the structure — closed book, a 75% mark, 90 minutes, and supervision rules dense enough to punish guessing — and that structure is what this guide is built around.

<a id="who-must-pass"></a>
## Who must pass the FHLR — every pathway to a Florida hygiene license
Florida has **no general reciprocity**: an out-of-state hygiene license alone never confers a Florida license, and every pathway in includes this examination.

| Pathway | Clinical exam | Laws & Rules exam | Authority |
| --- | --- | --- | --- |
| Licensure by examination (hygiene-program graduates) | ADEX Dental Hygiene Examination required | **Required** | [s. 466.007, F.S.](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0466/Sections/0466.007.html); rule 64B5-2.0135 |
| Out-of-state ADEX Dental Hygiene Examination score holders | Accepted if taken on or after June 1, 2010 (rule 64B5-2.0135(1)(a), F.A.C.) | **Required** | s. 466.007(5), F.S.; rule 64B5-2.0135 |
| **MOBILE endorsement** (licensed out-of-state hygienists) | **Waived** | **Required — not waived** | s. 456.0145, F.S.; rule 64B5-2.0141, F.A.C. |
| Internationally trained dentists via the hygiene statute | ADEX Dental Hygiene Examination required (unaccredited-school graduates clear a credentials review first) | **Required** | s. 466.007, F.S.; rule 64B5-2.0144, F.A.C. |

**New graduates and near-graduates.** The examination pathway (s. 466.007, F.S.) requires an application under oath, a completed education route, the National Board Dental Hygiene Examination, and both the ADEX Dental Hygiene Examination and the written Florida laws-and-rules examination — the FHLR. Under rule 64B5-2.014, F.A.C., final-year students of accredited programs who have completed their clinical coursework may sit examinations before graduation, so the FHLR can come off your list before your diploma does.

**Relocating hygienists: the clinical waiver never reaches this exam.** The Mobile Opportunity by Interstate Licensure Endorsement (MOBILE) Act, s. 456.0145, F.S., lets a hygienist with an active, unencumbered out-of-state license, at least 2 years of active practice in the preceding 4, and no discipline in the preceding 5 years obtain a Florida license without retaking the clinical examination. But the Board's endorsement rule, 64B5-2.0141, F.A.C., requires every dental **and dental hygiene** endorsement applicant to pass an examination on Florida's laws and rules. For an experienced relocating hygienist the FHLR is the one exam left standing — a closed-book exam on statutes and rules you have never practiced under, which is exactly why the [traps section](#traps) below is written for you. Note the rule is new (adopted December 2024, amended twice in 2025): prep material written before 2025 does not know this pathway exists.

**Out-of-state ADEX scores.** If you took the ADEX Dental Hygiene Examination in another state, Florida accepts a score from an administration **on or after June 1, 2010** (rule 64B5-2.0135(1)(a), F.A.C., under the out-of-state pathway of s. 466.007(5), F.S.) — but the file still needs the National Board and the FHLR. Unlike the dentist statute, the hygiene statute attaches **no 365-day staleness rule** to clinical scores; the year-based extra requirements in s. 466.006(4)(b) are dentist-pathway law.

**Internationally trained dentists: Florida's hygiene pathway includes you — and the FHLR comes with it.** Under s. 466.007, F.S., dental hygiene licensure is open not only to hygiene-program graduates but also to graduates of dental schools — accredited **or unaccredited** — who document **4 academic years of postsecondary dental education** and a diploma comparable to a D.D.S. or D.M.D., and pass either the National Board Dental Hygiene Examination or the National Board Dental Examination. Applicants from unaccredited schools clear a credentials review first under rule 64B5-2.0144, F.A.C. — Form DH-MQA 1253, a certified diploma copy with certified translation, transcripts sent directly from the school, and a year-by-year ECE-approved educational evaluation (advisory, not binding on the Board) — then sit the same two examinations as everyone else: the ADEX Dental Hygiene Examination **and** the FHLR. For a dentist trained abroad, Florida's statutes and Board rules are usually the least familiar part of the file; this guide and the [FHLR exam hub](/florida-dental-hygiene-laws-rules) exist for exactly that gap.

**You are the larger cohort.** Florida issued **more initial dental hygienist licenses than dentist licenses in FY 2024-25** (Florida MQA annual report) — and every one of those hygiene pathways ran through this exam.

<a id="registration"></a>
## Registering and scheduling: two tracks, two clocks
Getting a seat involves **two separate tracks with two separate organizations**, and knowing which one owns which step saves real calendar time.

**Track 1 — the license application, with the Board.** Your licensure application — examination, MOBILE endorsement, or the credentials-review pathway — runs through the Florida Board of Dentistry's [dental hygienist licensing page](https://floridasdentistry.gov/dental-hygienist/). Accredited-program applicants use Form DH-MQA 1210; internationally trained dentists entering through the hygiene statute use the credentials-review form, DH-MQA 1253 (rule 64B5-2.0144, F.A.C.). The statute caps the application fee at $100, and the Board's fee rule (64B5-15.002, F.A.C.) sets the hygiene application fee at $50. One quiet clock lives here: under s. 456.013, F.S., an **incomplete application expires one year after initial filing** — plan your exam sittings so a retake cycle cannot strand the file.

**Track 2 — the exam registration, with the vendor.** The FHLR itself is registered and paid through ADEX/CDCA's candidate portal (linked from the [Florida Laws and Rules page](https://adextesting.org/fl-laws-rules/)), and sittings are scheduled at Prometric test centers. The mechanics, per the vendor's FAQ: create a profile at Candidates.ADEXtesting.org, upload a professional photo and your qualifying document, allow **2-3 business days** for profile verification, then register and pay — after which a "Schedule My Exam" button books the Prometric appointment. **All scheduling, rescheduling, and cancellation run through that portal, not Prometric's website**, and any testing-accommodation request (with health-provider documentation) must be submitted and approved **before** you schedule. The 2026 ADEX Candidate Guide is the controlling document for fees, scheduling, credit expiration, and the conduct rules you agree to at the test center.

**Who can register when.** Per the Board's hygienist page, graduates of accredited programs complete the examinations first and file the licensure application after — "upon completion of the required examinations." Internationally trained and other credentials-review candidates are gated the other way: the Board must approve the credentials application first, and it then notifies ADEX/CDCA of your eligibility to register for the clinical and Laws and Rules examinations.

**What it costs, all-in.** $105 per exam attempt — and Florida prices every attempt identically: there is no discounted retake. Around it sit the Board application fee ($50 for dental hygiene under rule 64B5-15.002, F.A.C., within the statute's $100 cap) and vendor-priced fingerprint background screening through an approved Livescan provider. Budget for one sitting; know the full retake price going in.

**Two clocks run near this exam — and only one of them touches it:**

1. **Registration credits must be used — or refunded, minus administrative fees — within 2 years of the original payment date** (ADEX/CDCA vendor page). Registering long before you intend to schedule burns that clock for nothing. Register when your study plan has an end date.
2. **The ADEX 18-month completion window does not include this exam.** That window attaches to the clinical examination parts under rule 64B5-2.0135(3), F.A.C. — all parts of the ADEX Dental Hygiene Examination within 18 months, or the whole clinical series is retaken. The 2026 Candidate Guide lists the Laws and Rules exam as standalone. Plan the FHLR on its own calendar — rule-text walkthrough in [our 18-month-window note](/what-changed/florida-18-month-window-laws-rules).

**Sequencing.** A provisional pass/fail shows on screen at completion, official results post to your portal in 2-3 business days, and the 2026 ADEX Candidate Guide requires a **10-day waiting period** "between the date of failure and the re-attempt of any computer-based or clinical part" of an ABDE-administered examination — with retake registration opening only after the official result posts. So the practical constraints on a timeline are Prometric seat availability and, if you miss, the 10-day wait plus a full-fee retake cycle. Working backwards from whatever date your program, employer, or application file sets: leave room for scheduling lead time, the 2-3 day result cycle, and one contingency retake.

## What the FHLR actually tests: the 3% cap and where the other 97% lives
The published scope is exactly three sources, and Florida publishes exactly **one** content weight for this exam: rule 64B5-2.0135(2)(c) caps **Chapter 456** material at **3%**. Everything else — at least 97% — comes from the other two sources.

- **Chapter 466, Florida Statutes** — the Dental Practice Act: hygienist licensure (s. 466.007), hygienist scope of practice ([s. 466.023](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0466/Sections/0466.023.html)), dental charting (s. 466.0235), delegation (s. 466.024), discipline, records. Read it free at [Online Sunshine](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0466/0466.html).
- **Division 64B5, Florida Administrative Code** — the Board of Dentistry's rules, where the statutes become operational detail: the supervision definitions (64B5-16.001), the task-by-supervision-level lists (64B5-16.006), remediable-task training rules, CE hours, record content. The delegation chapter is [64B5-16 at flrules.org](https://www.flrules.org/gateway/ChapterHome.asp?Chapter=64B5-16).
- **Chapter 456, Florida Statutes** — general law for all Florida health professions: records ownership, unlicensed practice, the shared discipline grounds. Capped at 3% — skim it, but do not over-invest.

The exam vendor's own preparation notes point FHLR candidates at **ss. 466.007, 466.023, 466.0235, and 466.024, F.S., and rule chapters 64B5-2 and 64B5-16** — which is a fair one-line summary of where the questions concentrate: licensure mechanics plus the hygienist scope-supervision-delegation system.

**One warning inside the good news.** The rule defines the written examination as covering the laws and rules of a health care profession, **the practice of dentistry**, and the practice of dental hygiene — hygiene candidates cannot skip the dentist-side framework. The dentist of record, records retention, discipline, and advertising rules all bind the practice you work in, and items can test them from the hygienist's seat. What the 3% cap buys you is freedom from deep Chapter 456 detail — not freedom from Chapter 466.

Florida publishes no narrower topic weights. Dentovio's FHLR materials therefore organize study around the structure of the law itself — with the hygienist-role rules foregrounded and Chapter 456 held to its 3% cap in simulations — and the [next section](#supervision-and-scope) walks the territory the exam keeps returning to. The [glossary](/guide/florida-dental-laws-rules-exam/glossary) defines the 24 terms this vocabulary runs on.

<a id="supervision-and-scope"></a>
## Supervision levels and the hygienist scope map — the exam's center of gravity
If the FHLR has a center of gravity, it is the system built from s. 466.023, s. 466.024, and chapter 64B5-16: **who may do what, under which level of supervision, in which setting**. Learn it as a map, not a list.

**The three supervision levels — a checklist that loses elements as it loosens.** Florida defines three levels (rule 64B5-16.001, F.A.C.), and the cleanest way to hold them is by element count:

| Level | Elements the dentist must satisfy |
| --- | --- |
| **Direct** | Five: examine the patient, diagnose, authorize the procedure, be **on the premises** while it is performed, approve the work **before the patient leaves** |
| **Indirect** | Four: everything above **except** approval before departure |
| **General** | One: authorization — the dentist need **not be present**, and the work may occur at any location |

Two mechanics ride on that table. A **general-supervision authorization is valid at most 24 months**; once it lapses, no further general-supervision treatment until a Florida-licensed dentist performs a new clinical exam. And several states run a two-tier vocabulary (direct/general only) — Florida's **indirect** tier is the classic distractor for relocating hygienists.

**The hygienist-only trio.** Removing **calculus deposits** from exposed tooth surfaces and the gingival sulcus, **root planing**, and **gingival curettage** are delegable only to a dental hygienist — never to a dental assistant, no matter the training course (ss. 466.023 and 466.024(6), F.S.). Two things never leave the dentist at all: **prescribing** and **diagnosis/treatment planning**.

**The task map by level** (rule 64B5-16.006, F.A.C. — amended as recently as April 2026, so date any deck you study from): under **general** supervision — prophylaxis, root planing, radiographs, sealants, fluoride varnish and silver diamine fluoride, suture removal, periodontal dressings. Under **indirect** — rubber dams, matrices, liners and bases, temporary cementation of temporary crowns, assisting nitrous administration for ASA I–III patients. Under **direct** — gingival curettage, local anesthesia by a certified hygienist, intraoral fabrication of temporary crowns, retraction cord, nitrous assistance for special-needs and ASA IV patients.

**The hygiene-services prescription.** Outside the dentist's office, a hygienist may treat a dentist's **patient of record** — one on whom the dentist has taken a complete medical history, completed a clinical examination, recorded any pathological conditions, and prepared a treatment plan — on a written prescription (s. 466.023(2)(d), F.S.; rule 64B5-9.010, F.A.C.): valid **2 years** unless the dentist shortens it, naming the patient, the prescribing dentist, **the specific hygienist**, and the services with their frequency; the settings include the home of a nonambulatory patient. Contrast its 2-year life with the timers around it — the exam loves neighboring numbers.

**Dental charting** (s. 466.0235, F.S.; rule 64B5-16.0075, F.A.C.): a hygienist may record **visual observations only** — no X-rays, no lab tests — in listed settings such as schools, nursing homes, assisted living facilities, mobile units, and health fairs, after the patient acknowledges a disclosure form, with a written medical-clearance statement before any periodontal probing. Charting creates **neither a patient of record nor a medical record** — a statutory oddity Florida tests precisely because the vocabulary most candidates carry in (California's included) has no equivalent for it.

**Health access settings** (ss. 466.003(15) and 466.024(2)–(5), F.S.): in community health centers, FQHCs, school programs, and the other listed settings, a hygienist may perform six tasks **without supervision** — charting, vitals, case histories, ADA/FDA-accepted topical fluorides including varnish, sealants, and calculus removal — with hard conditions attached: **medical clearance before** removing calculus (a standing order is permitted), a **dentist examination within 13 months after**, a written disclaimer before every task, and **$100,000/$300,000** malpractice coverage. Root planing and curettage never join the unsupervised list.

**Local anesthesia by a certified hygienist** (s. 466.017(5), F.S.; rules 64B5-16.006(4) and 64B5-14.003, F.A.C.): after a Board-approved course of at least **30 didactic and 30 clinical hours** plus current BLS/ACLS, a certified hygienist may administer intraoral block and soft-tissue infiltration anesthesia — under **direct supervision**, to a **non-sedated** patient (nitrous-only counts as non-sedated for this purpose), **18 or older**. The certificate is one-time (fee capped at $35), part of the hygienist's permanent record, and prominently displayed where the anesthesia is administered. Around anesthesia generally: a hygienist assists **initiating nitrous** under indirect supervision after a minimum 2-day course or equivalent training in an accredited dental or dental hygiene program, and anesthesia adverse incidents carry a **48-hour** registered-mail notice to the Board plus a complete written report within **30 days**.

**Remediable-task training systems.** The hygienist restorative-functions rule (64B5-16.0061, F.A.C.) admits hygienists through an **85-clock-hour** course into placing, packing, and contouring restorations after the dentist prepares the tooth — always under direct supervision — and permits fitting and contouring a stainless-steel crown while reserving **permanent cementation to the dentist alone**. (Dental assistants enter restorative functions under their own, longer-course rule — keep the two systems separate.)

**Records, last.** The retention number is **4 years** (s. 466.018, F.S.; rule 64B5-17.002, F.A.C.), corrections are strike-through with date and initials — and a dental hygienist **cannot be a records owner** under s. 456.057, F.S., a one-line fact the exam can hang a whole scenario on.

That is the map. Notice how many **numbers with near neighbors** it contains — 24-month authorization, 2-year prescription, 13-month health-access exam, 4-year retention, 30+30 course hours, 48-hour notice — because that is precisely how the exam will test it.

<a id="traps"></a>
## The traps: carried-in assumptions that fail relocating hygienists
The two ways candidates get FHLR questions wrong are importing another state's law and studying from material written before Florida's recent rule changes. These are the highest-risk carryovers, verified against the Florida sources:

| Topic | Common carried-in assumption | **The Florida rule** |
| --- | --- | --- |
| Supervision vocabulary | Two hygienist tiers (direct/general) | **Three defined levels** — direct, indirect, general — with the 5-4-1 element checklist (rule 64B5-16.001) |
| General-supervision authorization | No expiration mechanic | Valid a **maximum of 24 months**; reset only by a new clinical exam (rule 64B5-16.001) |
| Record retention | 7 years | **4 years** from the last examination or treatment (s. 466.018, F.S.; rule 64B5-17.002) — corrections by legible strike-through, never deletion |
| Records ownership | Any treating clinician may hold records | A dental hygienist **cannot be a records owner** (s. 456.057, F.S.) |
| Local anesthesia | Course-based, conditions vary | Hard statutory conditions: **direct supervision, non-sedated patient, 18 or older**, after a 30-hour didactic + 30-hour clinical course (s. 466.017(5), F.S.) |
| CE per biennium | 25 hours (a common RDH number elsewhere) | **24 hours**, including the statutory courses — and **CPR certification counts for zero hours** (rule 64B5-12.013) |
| Dental charting | No dedicated statute | Florida has a standalone charting statute and form rule (s. 466.0235, F.S.; rule 64B5-16.0075) — eyes only, disclosure form first, clearance before probing |
| Stainless-steel crowns | Trained auxiliary may cement | Fit and contour yes; **permanent cementation never** (rule 64B5-16.0061) |
| Office safety | No AED-specific board rule | Operating without an on-site **AED is below the minimum standard of care** by rule (64B5-17.015) |
| Unlicensed practice | Not felony-graded at baseline | Third-degree **felony** (ss. 456.065 and 466.026, F.S.); practicing on a lapsed license grades by duration |
| Criminal pleas | Different plea treatment | A **nolo contendere** plea creates a rebuttable presumption of guilt, and grounds attach "regardless of adjudication" |
| Discipline statutes | One primary statute | **Two parallel ground lists** — s. 466.028 and s. 456.072, F.S. — and items quote both; own criminal convictions and out-of-state license actions are self-reported within **30 days** |

The rule of thumb: whenever your instinct supplies a number — a retention period, an hour count, a supervision condition — assume it is your old state's number until you have seen it in a Florida statute or rule.

**Stale Florida material fails you the same way.** The exam rule 64B5-2.0135 has a current version effective **June 1, 2026** ([what changed](/what-changed/florida-64b5-exam-rules-june-2026)); the MOBILE endorsement rule was adopted **December 2024**; the task-map rule 64B5-16.006 was amended in **April 2026**; and the Board's own Laws and Rules Booklet is a frozen **July 2023** snapshot — scope confirmation only, never a substitute for current text. A quick self-test for any study resource: does it cite the June 1, 2026 rule version, know the MOBILE pathway, and hold Chapter 456 to its 3% cap? If not, everything else it says needs re-verification.

Also keep the **interlocking timers** separate — they are natural distractors for each other: 24-month general-supervision authorization · 2-year hygiene-services prescription · 13-month health-access follow-up exam · 4-year record retention · 2-year registration-credit life.

## A five-part FHLR study plan built for retrieval
Florida publishes no typical preparation duration and no outcome-by-study-time data. Set your timeline from your starting point and exam date. Because the exam is closed book with a 75% mark, preparation is memorization of current rule text — numbers, notations, and element checklists — not open-book lookup practice. Start with a diagnostic so your available time goes where your gaps are: the [free FHLR practice test](/florida-dental-hygiene-laws-rules/free-practice-test) takes a few minutes and requires no signup.

| Step | Focus | The numbers to own before moving on |
| --- | --- | --- |
| 1 | Hygienist scope + the supervision map (ss. 466.023, 466.024, F.S.; rules 64B5-16.001, 64B5-16.006) | The 5-4-1 supervision checklist; 24-month authorization; hygienist-only trio; the assistant line (never scale, plane, or curette); the never-delegable pair (prescribing, diagnosis) |
| 2 | Charting, health access settings, local anesthesia (ss. 466.0235, 466.024(2)–(5), 466.017(5), F.S.; rule 64B5-16.0075) | Charting = eyes only, form first, clearance before the probe; health access: clearance before scaling, dentist exam within 13 months after, $100K/$300K coverage; anesthesia: 30+30 course, direct supervision, non-sedated, 18+ |
| 3 | Records + confidentiality (ss. 466.018, 456.057, F.S.; rule 64B5-17.002) | 4-year retention; strike-date-initial corrections; hygienists cannot own records |
| 4 | Discipline + CE + office rules (ss. 466.028, 456.072, 466.014, F.S.; rules 64B5-12.013, 64B5-17.015) | Two parallel ground lists; 30-day self-reports; nolo presumption; 24 CE hours with medical-errors 2h every biennium and domestic-violence 2h every third; CPR = zero hours; the AED rule |
| 5 | Chapter 456 skim (capped at 3%) + full timed review | Do not over-invest in 456 detail; drill Chapter 466 and 64B5 numbers; finish with a full run under the 90-minute clock |

**Why the plan is built on drills instead of re-reading.** The learning-science literature is unusually consistent for exams like this — dense regulatory facts recalled without references. **Practice testing** is one of the two techniques rated "high utility" across hundreds of studies (Dunlosky et al. 2013, [review](https://journals.sagepub.com/doi/10.1177/1529100612453266)), and the classic Roediger & Karpicke experiments showed far better week-later retention for tested material than re-studied material. **Spacing** reviews on gaps of days beats massing them into one sitting (Cepeda et al. 2008, [paper](https://pubmed.ncbi.nlm.nih.gov/19076480/)). Re-reading and highlighting rank among the **lowest-utility** techniques — they create what the literature calls an illusion of competence, which is precisely the failure mode on legally dense text you will not have in front of you at Prometric. A closed-book exam is a retrieval exam; prepare by retrieving.

Three habits that fit this exam's design: **(1) Learn numbers in contrast pairs** — 24-month authorization vs 2-year prescription vs 13-month health-access exam vs 4-year retention; the natural distractor is always a neighboring number. **(2) Answer every item.** Up to 5 items are unscored field-test questions and results are pass/fail — an unanswered item can only score zero. **(3) Study the current text.** Where a rule was amended June 1, 2026 or April 2026, quiz yourself from the post-amendment version, because the superseded text is precisely what stale prep will have taught you.

## Practice questions: what the free decks get wrong, and the felony line
**Disclosure, first:** Dentovio — the publisher of this guide — sells paid FHLR prep. This section maps the whole landscape anyway, including the completely free path, because the comparison survives it.

**The official free stack.** Everything the exam draws from is free to read online: [Chapter 466](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0466/0466.html) and [Chapter 456, F.S.](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0456/0456.html), at Online Sunshine; every Division 64B5 rule at flrules.org, including [the exam rule itself](https://www.flrules.org/gateway/ruleNo.asp?id=64B5-2.0135) and [the delegation chapter](https://www.flrules.org/gateway/ChapterHome.asp?Chapter=64B5-16); and the [ADEX/CDCA vendor page](https://adextesting.org/fl-laws-rules/) with the 2026 Candidate Guide. It is authoritative by definition. The practical costs: the sources run to hundreds of sections, nothing tells you which provisions are exam-typical, the raw text carries no practice questions — the study format the learning science rates highest for a closed-book exam — and you become your own currency-tracker.

| Resource | Price | The honest read |
| --- | --- | --- |
| Official free stack (statutes + rules + vendor page) | $0 | Authoritative by definition; no practice engine; you do the translating and the currency-tracking |
| Crowd-sourced flashcard decks (Quizlet and similar) | $0 | Rarely dated, rarely updated after the creator passes; a deck written before December 2024 cannot know the MOBILE rule, and one written before June 2026 quotes superseded exam-rule text — most are dentist-weighted besides |
| User-uploaded PDF marketplaces (Studocu, Scribd, Docsity and similar) | low one-time prices | Seller-written banks of unverifiable provenance and date; you cannot audit one before buying it, and any deck marketed as *actual* or *real exam questions* is the product of a felony (below) |
| Multi-exam prep platforms | time-limited passes | Breadth plays; before paying, check the Florida hygiene module cites the current statutes and the June 1, 2026 rule version, and that its weighting is hygienist-specific rather than shared with the dentist exam |
| **Dentovio FHLR prep** (that's us) | $79 one-time | Statute-cited study modules with hygienist scope, supervision, and delegation foregrounded, an original question bank tagged for hygiene candidates with Chapter 456 capped at 3% in simulations — like the real exam — scenario drills, and cram sheets; 180 days of access — [details](/products/florida-dental-hygiene-laws-rules) |

**Start free either way:** the [free FHLR practice test](/florida-dental-hygiene-laws-rules/free-practice-test) is 15 original exam-style questions drawn across the study modules with rationales and statute citations, no signup — enough to locate your gaps before you spend a dollar or an hour.

**The felony line inside the gray market.** Florida law makes the theft, reproduction, or copying of a licensure examination — in whole or in part, by any means — a **third-degree felony** (s. 456.018, F.S.), and candidates sign a non-disclosure agreement at Prometric. A deck marketed as "actual FHLR questions" or "recalled questions" can only exist through that felony, so no legitimate Florida prep may contain recalled items — and every question on such a deck is unverifiable anyway. Every Dentovio item is original, written from the statutes and rules — never from exam recall — which is a legal requirement before it is a marketing point.

<a id="exam-day-retakes"></a>
## Exam day at Prometric, results, and the full-fee retake economics
**Delivery.** Computer-based at **Prometric test centers**, administered by ADEX/CDCA under contract with the Florida Department of Health. The sitting is **closed book**: no statute or rule text is provided or permitted, and use of unauthorized aids or reference materials is a conduct violation under the 2026 ADEX Candidate Guide. Bring **two original, current IDs**: a primary U.S. government-issued photo ID showing your name, photograph, and signature (driver's license, military ID, passport, or passport card) plus a secondary ID — and every ID except a passport must be in English (vendor FAQ). Confirm your appointment details and the current conduct rules in the Candidate Guide before your date.

**The clock.** 90 minutes for up to 64 items is roughly **84 seconds per item**. That is comfortable for one-line recall ("how long is a general-supervision authorization valid?") and tight for scenario stems that stack a supervision level, a task, and a setting. Flag and return rather than stalling; an unanswered item can only score zero.

**The scoring math is not published.** Up to 5 items are unscored field-test questions, and because every published count is an "up to" figure, no exact "you can safely miss N questions" number is honest — study materials that compute one are doing arithmetic on assumptions the vendor does not publish. Treat every item as scored and aim your preparation comfortably above the 75% line rather than at it.

**Results.** Pass/fail only, in two stages: a **provisional result appears on screen immediately** when you finish, and the **official result posts to your candidate portal within 2-3 business days** (vendor FAQ). Either way there is no numeric score, no content-area breakdown, and no diagnostic report — which is one more reason to diagnose your weak areas **before** the sitting with the [free practice test](/florida-dental-hygiene-laws-rules/free-practice-test) rather than hoping to learn them from a score report that will never come.

**Is it hard?** The only honest answer runs through the structure, because **Florida publishes no pass rate and no difficulty statistics for this exam**. What the structure says: closed book where several states run open book, a 75% mark, 90 minutes, and a scope whose center — the supervision-and-scope map above — is dense with near-neighbor numbers. That format rewards retrieval practice on current rule text and punishes another state's carried-in vocabulary — which is a study-method problem, not a mystery. Ignore both the scare figures and the reassuring ones you see elsewhere — none of them has a source.

**If you fail: the economics, plainly.** Every sitting is the same full **$105** — there is no discounted retake. **No attempt limit is published** for the Laws and Rules exam under s. 466.009, F.S., or the Candidate Guide, but ADEX policy sets a **10-day waiting period** between the date of failure and any re-attempt of a computer-based ABDE-administered examination, and retake registration opens only once your official result has posted; beyond that, the practical constraints are Prometric seat availability, money, and your vendor **registration credits expiring 2 years** from the original payment. (The part-by-part clinical retake rules — including the prophylaxis-failure full-retake rule and the three-failure remediation requirement — belong to the ADEX clinical exam, not to the FHLR.)

**The rebuild, in order:** (1) diagnose by content area yourself with the [free practice test](/florida-dental-hygiene-laws-rules/free-practice-test), because the exam will not tell you what missed; (2) audit your materials for staleness — if they did not cite the June 1, 2026 rule version or know the MOBILE pathway, rebuild from current-text sources rather than re-reading the same deck harder; (3) convert re-reading into retrieval, because the illusion-of-competence trap is strongest on a second pass through familiar material; (4) rebook only after a full timed run holds above the 75% mark with margin.

<a id="after-you-pass"></a>
## From pass result to license — and the numbers that follow you
A pass is a prerequisite, not a license. What follows the 2-3 business-day result:

**Your licensure file completes with the Board, not the vendor.** The pass belongs to whichever pathway you are on — examination or credentials-review (s. 466.007, F.S.) or MOBILE endorsement (s. 456.0145, F.S.) — and the remaining requirements run through the [Florida Board of Dentistry's dental hygienist page](https://floridasdentistry.gov/dental-hygienist/). Confirm your pathway's current checklist there.

**Background screening is part of licensure.** Under s. 456.0135, F.S., fingerprint-based background screening is a licensure requirement for the chapter 466 professions — and a 2024 session law extends it to practitioners licensed before July 1, 2025, by their first renewal on or after that date.

**The same law keeps governing you after the license issues** — and several of its numbers recur immediately:

- **CE:** at least **24 hours** per biennium for hygienists, including 2 hours of medical-errors CE every biennium, 2 hours of domestic-violence CE every **third** biennium, and a one-time HIV/AIDS course by first renewal — and **CPR certification counts for zero hours** and must be current every biennium (ss. 466.014, 456.031, and 456.033, F.S.; rule 64B5-12.013, F.A.C.).
- **Renewal:** biennial; the hygiene renewal fee is **$75** (rule 64B5-15.006, F.A.C.).
- **30-day self-reports:** action against your license in another state, and any criminal conviction or plea, are reportable to the Board within 30 days (ss. 466.028 and 456.072, F.S.).
- **Display and address:** the license is displayed in plain sight at each practice location, and keeping your mailing address and place of practice current with the department is solely your responsibility under s. 456.035, F.S. — the statute sets no grace period (figures like "10 days" circulating in flashcard decks are not in it), failing to update is itself a disciplinable violation, and official mail to your last address of record counts as delivered.
- **The scope map:** the supervision levels, the 24-month authorization, the charting rules, and the 4-year records clock move straight from exam material to daily compliance material from your first Florida patient.

Already licensed and here about renewal instead? That is a different page — [Florida dental license renewal requirements](/dental-license-renewal/florida) covers the renewal-cycle rules for both professions.

The practical upshot: do not throw your notes away on results day. The rules you memorized are the rules you will practice under — which is also why FHLR study access runs 180 days from purchase rather than ending at your exam date.

## Questions candidates actually ask

### How many questions are on the Florida Dental Hygiene Laws and Rules Exam, and how long do I get?

The FHLR is **up to 64 multiple-choice items** — including up to 5 unscored field-test items — in **90 minutes**, computer-based at Prometric test centers. That is roughly 84 seconds per item at the full count. The count is published as an "up to" figure on the [live vendor page](https://adextesting.org/fl-laws-rules/).

### What score do I need to pass the FHLR?

**75% or higher**, set by [rule 64B5-2.0135, F.A.C.](https://www.flrules.org/gateway/ruleNo.asp?id=64B5-2.0135) Results are reported **pass/fail only** — you never see a numeric score or a content-area breakdown.

### Is there a free study guide for the Florida Dental Hygiene Laws and Rules Exam?

Yes — this page is one, and it is free deliberately: the format facts, the scope with its 3% Chapter 456 cap, the supervision-and-scope map, the trap table, and the five-part study plan above cover the ground a paid outline would. Pair it with the [free FHLR practice test](/florida-dental-hygiene-laws-rules/free-practice-test) (15 original questions with rationales, no signup) and the official free stack — the statutes at Online Sunshine, the rules at flrules.org, and the vendor page. The paid Dentovio FHLR system adds the full statute-cited modules, question bank, and drills.

### Is the FHLR the same as the dentist Florida Laws and Rules exam?

No. The FHLR is a **separate examination** under its own rule (64B5-2.0135, F.A.C.), with its own item count (up to 64 vs the dentist FDLR's up to 67), its own fee ($105 vs $135), and the 3% Chapter 456 cap the dentist exam does not have. The exams draw on the same body of Florida law with different emphasis. Dentist candidates should use [the FDLR guide](/guide/florida-dental-laws-rules-exam/how-to-pass) instead.

### What does the FHLR cover — and how much of it is Chapter 456?

Three sources: **Chapter 466, Florida Statutes** (the Dental Practice Act), **Division 64B5, F.A.C.** (the Board's rules), and **Chapter 456, Florida Statutes** — with rule 64B5-2.0135(2)(c) capping Chapter 456 at **3%** of the exam. At least 97% comes from the dental-specific sources, concentrated on hygienist scope, supervision, and delegation. **Chapter 64B27 is not in the live scope** — it appeared only in the legacy 2019 booklet.

### What are Florida's three supervision levels for dental hygienists?

**Direct**, **indirect**, and **general** (rule 64B5-16.001, F.A.C.) — a checklist that loses elements as it loosens: direct has five elements (examine, diagnose, authorize, dentist on premises, approval before the patient leaves), indirect keeps four (drops only the departure approval), and general keeps one (authorization — the dentist need not be present). A general-supervision authorization is valid at most **24 months**. Florida's **indirect** tier is the classic trap for hygienists trained under a two-tier vocabulary.

### Can a dental hygienist administer local anesthesia in Florida?

Yes, with a certificate and hard conditions: after a Board-approved course of at least **30 didactic and 30 clinical hours** plus current BLS/ACLS, a certified hygienist may administer intraoral block and soft-tissue infiltration anesthesia — under **direct supervision**, to a **non-sedated patient** (nitrous-only counts as non-sedated), who is **18 or older** (s. 466.017(5), F.S.). The certificate is one-time, part of the hygienist's permanent record, and prominently displayed where the anesthesia is administered. Soften any one condition and the answer is wrong — the exam tests them as a set.

### How much does the FHLR cost, and how do retakes work?

**$105 per attempt** — the initial sitting and every retake cost the same full fee. **No attempt limit is published**, and ADEX policy sets a **10-day waiting period** between the date of failure and any re-attempt, with retake registration opening only after your official result posts. Vendor registration credits expire **2 years** from the original payment date. The [retake plan above](#exam-day-retakes) covers the rebuild sequence.

### Is the FHLR open book?

No. The FHLR is **closed book** at Prometric test centers — no statute or rule text is provided or permitted, and reference materials and electronic devices are conduct violations under the 2026 ADEX Candidate Guide. Several states run open-book jurisprudence exams; candidates who assume Florida works that way prepare the wrong skill entirely.

### Is the FHLR part of the ADEX 18-month completion window?

No. The 18-month window in rule 64B5-2.0135(3), F.A.C., attaches to the ADEX **clinical** examination parts — all parts of the ADEX Dental Hygiene Examination within 18 months. The 2026 ADEX Candidate Guide lists the Laws and Rules exam as a standalone computer-based exam. The only expiration touching the FHLR is that **registration credits expire 2 years from payment**. Full rule walkthrough in [our dated note](/what-changed/florida-18-month-window-laws-rules).

### I'm a licensed hygienist moving to Florida — do I still take the FHLR?

Yes. Florida has **no general reciprocity**. The MOBILE endorsement pathway (s. 456.0145, F.S.) waives the clinical examination for qualifying out-of-state licensees, but rule 64B5-2.0141, F.A.C., expressly requires every dental and dental hygiene endorsement applicant to pass the Florida Laws and Rules examination. Relocating hygienists are also the group most at risk from carried-in assumptions — see [the trap table](#traps).

### I'm an internationally trained dentist — can I take the FHLR and become a Florida dental hygienist?

Florida's hygiene statute makes this pathway possible, and yes — the FHLR is part of it. Under s. 466.007, F.S., dental hygiene licensure is open to graduates of dental schools — accredited **or unaccredited** — who document 4 academic years of postsecondary dental education and a diploma comparable to a D.D.S. or D.M.D., and pass either the National Board Dental Hygiene Examination or the National Board Dental Examination. Applicants from unaccredited schools complete a credentials review first (rule 64B5-2.0144, F.A.C., Form DH-MQA 1253 with an ECE-approved evaluation), then sit the ADEX Dental Hygiene Examination **and** the FHLR. Confirm the current application requirements with the [Florida Board of Dentistry](https://floridasdentistry.gov/dental-hygienist/).

### What is the pass rate for the FHLR — and is it hard?

**Florida publishes no pass rate for this exam** — not the Board, not the department, not the vendor — and results are pass/fail only, so no score distributions exist publicly either. Any specific percentage you see elsewhere is unsourced. Judge difficulty from the published structure instead: closed book, a 75% mark, 90 minutes, and a supervision-and-scope core dense with near-neighbor numbers — a format that rewards retrieval practice on current rule text and punishes another state's vocabulary.

### How long should I study for the FHLR?

Florida publishes no typical preparation duration and no outcome-by-study-time data. Set your timeline from your starting point and exam date. Start with the [free FHLR practice test](/florida-dental-hygiene-laws-rules/free-practice-test) so your available study time goes to your actual gaps, then run the [five-part plan above](#study-plan) at whatever pace your calendar allows.

### When and how do FHLR results come out?

In two stages, **pass/fail only**: a provisional result appears **on screen immediately** when you finish, and the official result posts to your online candidate portal within **2-3 business days** (vendor FAQ). There is no numeric score and no content-area breakdown at either stage — the exam gives you no diagnostic information after the fact, which is why testing yourself by content area *before* the sitting matters.
