The questions, the instant score, the weak-block map, and every answer rationale are free. There is no signup to start and no email required to see your results. ### Are these real questions from the RDH Laws and Ethics Written Examination? No. Dentovio uses original exam-style questions written against the DHBC's published 2025 examination outline. It does not reproduce official, live, recalled, or confidential DHBC or PSI exam items. ### What does the practice test cover? 15 questions distributed across the seven blocks of the DHBC's official 2025 outline (1A Informed Consent through 3B Obligations within the Professional Role), so every block of the official outline is sampled. Treat a 15-question score as directional. ### Is this for the RDH exam or the dentist / RDA exam? This practice test targets the Registered Dental Hygienist (RDH) Laws and Ethics Written Examination run by the Dental Hygiene Board of California. The dentist Law and Ethics exam (Dental Board of California) and the RDA Combined Written Exam are separate exams with different outlines and different scoring rules. ### What happens after I finish the practice test? You see your score, a block-by-block breakdown against the official 2025 outline, every question's rationale, and a retest of the questions you missed. Finishing also unlocks the $89 diagnostic-completion price for the full prep instead of the regular $99 price. ## Primary sources - **RDH-CIB** — [PSI Candidate Information Bulletin — RDH Laws and Ethics Written Examination (January 2026)](https://www.dhbc.ca.gov/formspubs/candidate_handbook.pdf) - **DHBC-LAWS-2025** — [DHBC 2025 Laws and Regulations book (Dental Hygiene Practice Act + 16 CCR Division 11, including §1121)](https://www.dhbc.ca.gov/lawsregs/new_dhbc_2025_laws_and_regulations_book.pdf) - **DHBC-CHECKLIST** — [DHBC “How To Qualify for a RDH License” informational and application checklists ($200 fee, process flowchart)](https://www.dhbc.ca.gov/formspubs/rdh_informational.pdf) - **BPC-1917** — [Business and Professions Code §1917 — RDH licensure requirements (leginfo)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=BPC§ionNum=1917.) - **DHBC-SUNSET-2023** — [Joint Sunset Review Background Paper — Dental Hygiene Board of California (2023; pass rates, fees, English-only)](https://abp.assembly.ca.gov/sites/abp.assembly.ca.gov/files/3-16%203.%20Dental%20Hygiene%20Board%20-%20Sunset%20Background%20Paper%20(2023).pdf) ## Disclosures - Dentovio is an independent publisher.
