# Florida Dental Hygiene Laws and Rules Exam (FHLR): Format, Fee, Scope > The FHLR at a glance: up to 64 items in 90 minutes, closed book at Prometric, 75% to pass, $105 per attempt, and a scope built on Chapter 466 and Division 64B5 with Chapter 456 capped at 3%. URL: https://dentovio.com/florida-dental-hygiene-laws-rules Markdown: https://dentovio.com/florida-dental-hygiene-laws-rules/index.html.md Last verified: 2026-07-26 The Florida Dental Hygiene Laws and Rules Exam (FHLR) is a closed-book, 90-minute examination on Florida dental hygiene law, administered by ADEX/CDCA under contract to the Florida Board of Dentistry at Prometric test centers, and required on every pathway to a Florida dental hygiene license. It is a separate exam from the dentist FDLR, with its own rule (64B5-2.0135, F.A.C.), item count, and fee. ## The exam at a glance - **Questions: Up to 64 multiple-choice items** — Including up to 5 unscored field-test items. Answer every question as if it counts — you cannot tell which items are unscored. - **Time: 90 minutes** — Roughly 84 seconds per item at the full 64-item count. - **Passing mark: 75% or higher** — Results are reported pass/fail only, in 2-3 business days. No numeric score breakdown is published. - **Fee: $105 per attempt** — Initial attempt and each retake alike. Registration credits expire 2 years from payment; no attempt limit is published. - **Delivery: Computer-based at Prometric test centers, closed book** — Administered by ADEX/CDCA under contract to the Florida Board of Dentistry. A separate exam from the dentist FDLR — different rule, item count, and fee. - **Scope: Chapter 466 F.S. + Division 64B5 F.A.C., with Chapter 456 capped at 3%** — Rule 64B5-2.0135(2)(c) caps Chapter 456 content at 3%, so nearly the whole exam is the Dental Practice Act and the Board's rules — scope, supervision, and delegation. ## Why the scope favors supervision and delegation questions Rule 64B5-2.0135(2)(c) caps **Chapter 456** content at **3%** of the exam. Nearly everything you are tested on comes from **Chapter 466, Florida Statutes** (the Dental Practice Act) and **Division 64B5, F.A.C.** — which is where hygienist scope of practice, supervision levels, delegable and remediable tasks, and recordkeeping duties live. Rule 64B5-2.0135 has a current version effective **June 1, 2026**; the written exam requirement and the 75% mark were unchanged by that amendment. Chapter 64B27 appeared only in the legacy 2019 booklet and is not in the live scope. ## Who must take it Every pathway to a Florida dental hygiene license includes the FHLR — Florida has no general reciprocity, so hygienists relocating from other states sit it too. Florida dental hygiene candidates are the larger of the two cohorts: **1,767** initial dental hygienist licenses vs 1,380 dentist licenses in FY 2024-25 (Florida MQA annual report). The FHLR is standalone: the ADEX 18-month completion window covers the clinical examination parts, not this exam. Registration credits expire 2 years from payment. ## Study path - [Free FHLR practice test](https://dentovio.com/florida-dental-hygiene-laws-rules/free-practice-test/index.html.md) — original exam-style questions, no signup. - [Florida Dental Laws and Rules exam guide](https://dentovio.com/guide/florida-dental-laws-rules-exam/index.html.md) - [How to pass the Florida Laws and Rules exams](https://dentovio.com/guide/florida-dental-laws-rules-exam/how-to-pass/index.html.md) - [Dentovio's FHLR prep product](https://dentovio.com/products/florida-dental-hygiene-laws-rules/index.html.md) — checkout is available: one-time $79, 180 days of access.

Up to 64 multiple-choice items — including up to 5 unscored field-test items — in 90 minutes, computer-based at Prometric test centers. The exam is closed book: no statute or rule text is provided or permitted. ### Is the FHLR the same exam as the dentist FDLR? No. The Florida Dental Hygiene Laws and Rules Exam is a separate examination under its own rule, 64B5-2.0135, F.A.C., with its own item count (up to 64 vs up to 67) and its own fee ($105 vs $135). Prep written for the dentist exam over-weights dentist-only duties and under-weights hygienist scope and supervision. ### What score do I need to pass the FHLR? 75% or higher. Results are reported pass/fail only, in 2-3 business days — no numeric score breakdown is published. ### What does the FHLR cover? Chapter 466, Florida Statutes (the Dental Practice Act) and Division 64B5 of the Florida Administrative Code, with Chapter 456 content capped at 3% by rule 64B5-2.0135(2)(c). In practice that means the exam lives in hygienist scope of practice, supervision levels, delegable and remediable tasks, and recordkeeping duties. ### How much does the FHLR cost, and how do retakes work? $105 per attempt — the initial sitting and each retake cost the same full fee. Registration credits expire 2 years from payment, and no attempt limit is published in the rules or the Candidate Guide. ### Who has to take the Florida Dental Hygiene Laws and Rules Exam? Every pathway to a Florida dental hygiene license includes it — Florida has no general reciprocity, so hygienists relocating from other states sit this exam too. Hygienists are also the larger Florida cohort: 1,767 initial dental hygienist licenses vs 1,380 dentist licenses in FY 2024-25, per the Florida MQA annual report. ### What is the pass rate for the FHLR? Florida does not publish a pass rate for this exam, and any specific figure you see elsewhere is unsourced. Judge difficulty from the structure instead: closed book, a 75% mark, 90 minutes, and delegation rules dense enough that another state's supervision vocabulary will mislead you. ### How long do candidates usually prepare? Candidates typically prepare for 4-6 weeks, and exam volume clusters in April through July around graduation. Because the exam is closed book with a 75% mark, the preparation is memorization of current rule text — not open-book lookup practice. ## Primary sources - **FL-ADEX** — [ADEX/CDCA — Florida Laws and Rules examination page (exam vendor, under contract to the Florida Board of Dentistry)](https://adextesting.org/fl-laws-rules/) (verified 2026-07-26) - **FL-CG-2026** — [2026 ADEX Candidate Guide, v20251024 (exam vendor — fees, item counts, scheduling, credit expiration)](https://adextesting.org/wp-content/uploads/2026/01/Candidate-Guide_20251024.4.pdf) (verified 2026-07-26) - **FL-64B5-2013** — [Rule 64B5-2.013, F.A.C. — Licensure Examination for Dentists (Florida Administrative Code, current version effective June 1, 2026)](https://www.flrules.org/gateway/ruleNo.asp?id=64B5-2.013) (verified 2026-07-26) - **FL-64B5-20135** — [Rule 64B5-2.0135, F.A.C. — Licensure Examination for Dental Hygienists (Florida Administrative Code, current version effective June 1, 2026)](https://www.flrules.org/gateway/ruleNo.asp?id=64B5-2.0135) (verified 2026-07-26) - **FL-BOARD-DENTIST** — [Florida Board of Dentistry — Dentist licensing page (state regulator)](https://floridasdentistry.gov/dentist/) (verified 2026-07-26) - **FL-BOARD-HYGIENIST** — [Florida Board of Dentistry — Dental hygienist licensing page (state regulator)](https://floridasdentistry.gov/dental-hygienist/) (verified 2026-07-26) - **FL-CH466** — [Chapter 466, Florida Statutes — the Florida Dental Practice Act (state legislature, Online Sunshine)](http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0400-0499/0466/0466.html) (verified 2026-07-26) ## Disclosures - Dentovio is an independent publisher.
