Source-cited study modules across all four content areas of the Dental Board's 2023 outline — including the 50% Dental Procedures area, the 25% infection-control area, and the permitted-duties and law area — a question bank with answer rationales, a full-length practice exam, and quick-review sheets. ### How much does it cost? A one-time $69. Finish the free practice test first and the price is $49 instead. Access to the study materials is provided for 180 days from the date of purchase. ### I'm on the work-experience pathway with no school behind me. Is this built for me? Yes — that is the candidate this prep is built around. A large share of RDA candidates qualify by work experience or preceptorship rather than a school program, which means studying with no instructor, no syllabus, and no mock exams. In the Dental Board's June 2026 report, work-experience-pathway candidates passed at 62% against 79% for board-approved-program candidates. The modules follow the official outline so nothing on the blueprint goes uncovered. ### Has a credentialed reviewer signed off on this content? Yes. Mahtab Mansour, DDS reviewed and signed off on the RDA study content on July 24, 2026, across both the clinical assisting areas and the law and infection-control areas. Rules also trace to primary sources — BPC §1752.1, the Board's regulations including the permitted-duties table effective January 1, 2025, and the official 2023 examination outline. Her approval is recorded against each file's exact content digest, so any later edit clears it and returns that file to pending review. Review is not a pass guarantee. ### Is Dentovio affiliated with the Dental Board of California or PSI? No. Dentovio is an independent publisher. It is not the Dental Board of California, PSI, or an official government service, and all practice questions are original exam-style material — never recalled exam items. ### Does Dentovio guarantee I will pass? No. Dentovio makes no pass guarantee and no outcome promise. The Board's June 2026 report shows 72% of candidates passing and only 38% of repeat testers passing. What the prep adds is current, source-cited material keyed to the exam as it stands in 2026 — 125 items, criterion-referenced scoring, and the duties rules effective January 1, 2025. ## Primary sources - **DBC-RDA-OUTLINE** — [Dental Board of California — RDA Combined Written and Law and Ethics Examination Outline (2023 OPES occupational analysis)](https://www.dbc.ca.gov/formspubs/rda_exam_outline.pdf) - **DBC-RDA-APPLICANTS** — [Dental Board of California — RDA licensure applicant page (pathways, required certificates, application flow)](https://www.dbc.ca.gov/applicants/become_licensed_rda.shtml) - **DBC-RDA-STATS** — [Dental Board of California — RDA examination statistics, monthly reports (2026 series)](https://www.dbc.ca.gov/applicants/rda_written_exam_stats_2026.shtml) - **DBC-RDA-STATS-0626** — [Dental Board of California — RDA examination statistics, June 2026 report (263 candidates, 72% passed)](https://www.dbc.ca.gov/formspubs/rda_062026.pdf) - **BPC-1752-1** — [Business and Professions Code §1752.1 — RDA eligibility pathways, required course certificates, and the written examination requirement, as re-enacted by SB 1453 (operative July 1, 2025)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=1752.1.&lawCode=BPC) - **DBC-DUTIES-2025** — [Dental Board of California — Table of Dental Auxiliary Duties Delegable by Supervising Dentist (effective January 1, 2025)](https://www.dbc.ca.gov/formspubs/pub_permitted_duties.pdf) - **PSI-RDA-CIB** — [PSI — Candidate Information Bulletin and test-taker portal for the California RDA written examination (125 items, 3 hours, exam fee, scheduling and retakes)](https://test-takers.psiexams.com/) ## Disclosures - Dentovio is an independent publisher.
