Last verified July 24, 2026 · How Dentovio verifies content
A dentist leaves the building for a two-hour lunch meeting and asks the RDA to take blood pressure and pulse on the three patients scheduled that afternoon so the readings are ready when he returns. What is the correct analysis?
No signup, no email wall — your score, weak-block map, and every rationale appear as soon as you answer the last question.
Practice-test FAQ
Free RDA practice test questions, answered
Is this California RDA practice test really free?
Yes. The questions, the instant score, the weak-area 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 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.
