A large share of RDA candidates qualify by work experience or preceptorship, not school — no instructor, no syllabus, no mock exams. In the Board's June 2026 report that group passed at 62% against 79% for board-approved-program candidates. This prep supplies the structure the program would have.
Every rule in the modules cites the section it comes from — the Dental Practice Act, the Board's regulations, 16 CCR §1005, or Cal/OSHA's 8 CCR §5193 — so you can verify anything against the free official text.
No practical exam, one combined written exam, 125 items, criterion-referenced scoring instead of a fixed 75%, and a permitted-duties table restructured on January 1, 2025. The prep flags exactly these traps so older materials do not cost you points.
What's inside
Instead of piecing together the Dental Practice Act, office habit, and outdated PDFs, you move through the same areas the Board tests — from patient assessment (1A, 8%) through laws and regulations (Area 4, 10%).

Review status, plainly
Every material rule in this product traces to a primary source — BPC §1752.1, the Board's regulations, the permitted-duties table effective January 1, 2025, the 2023 examination outline, or the statute it teaches. Mahtab Mansour, DDS reviewed and signed off on this content on July 24, 2026, across both the clinical assisting areas and the law and infection-control areas. 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, and there is none.

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.
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.
