What the CP exam covers

DANB's CP Exam Outline, effective 03/12/2025 and read October 12, 2026, weights four domains: evaluation 15%, equipment and supplies 20%, procedures 39% and administration 26%. The 52 questions here are split 8, 10, 20 and 14.

The timed test

DANB's exam is computer adaptive. The timed test on this page is not: it asks 50 questions in 40 minutes, the pace the outline sets, and counts the number right.

Where the facts come from

CDC's 2003 dental infection control guideline, OSHA's Hazard Communication Standard and the HIPAA Privacy Rule, with MedlinePlus and named Wikipedia articles for stains, deposits and polishing technique.

  • The outline's references are textbooks, so a few technique rows, such as patient positioning, have no question here: no public page confirmed the facts.
  • Passing CP gives authority to polish only in states that recognize it; each state's dental board sets the rules.

Questions and answers

How many questions are on the DANB CP exam?

The CP Exam Outline, effective 03/12/2025, lists 75 multiple-choice questions and 60 minutes. DANB's CP exam page showed 80 test questions on October 12, 2026, so check the figure on your own exam confirmation.

What is a passing score on the DANB CP exam?

A scaled score of 400 on a scale that runs from 100 to 900. The outline adds that on this adaptive test the average candidate answers around 50% of the questions correctly.

Is the CP exam part of the CPFDA certification?

Yes. The outline names three component exams of the Certified Preventive Functions Dental Assistant certification: Coronal Polishing (CP), Sealants (SE) and Topical Fluoride (TF).

Are these real DANB CP exam questions?

No. Each question was written for this page from the public outline and the public page it names. The outline lists the DALE Foundation's DANB CP Practice Test as a study resource; nothing here comes from it.
