There is no signup to start and no email required to see your results. ### Are these real questions from the RDA Combined Written Exam? No. Dentovio uses original exam-style questions written against the Dental Board's published 2023 examination outline. It does not reproduce official, live, recalled, or confidential Dental Board or PSI exam items. ### What does the practice test cover? 15 questions spread across all four areas of the official 2023 outline in their tested proportions: Assessment and Diagnostic Records (15%), Dental Procedures (50%), Infection Control and Health and Safety (25%), and Laws and Regulations (10%). Treat a 15-question score as directional. ### Is this for the RDA exam or the dentist / RDH exam? This practice test targets the Registered Dental Assistant Combined Written and Law and Ethics Examination run by the Dental Board of California. The dentist Law and Ethics exam and the RDH Laws and Ethics exam (Dental Hygiene Board of California) are separate exams with different outlines and different scoring rules. ### What happens after I finish the practice test? You see your score, an area-by-area breakdown against the official 2023 outline, every question's rationale, and a retest of the questions you missed. Finishing also unlocks the $49 diagnostic-completion price for the full prep instead of the regular $69 price. ## 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.
