Online Test Prep - COTA Exam

NBCOT offers online COTA practice tests that mirror the format and flow of taking timed examinations on a computer. Each practice test consists of 100 items reflecting current COTA certification examination content.  Candidates are able to purchase and take these tests 24 hours a day wherever Internet access is available.

The COTA practice tests are offered in either a 2-hour version, simulating certification exam timed conditions, or a double-time 4-hour version. (The practice test clock automatically accommodates for slow modems or busy Web periods.) At the end of the practice test, candidates will instantly receive an online feedback report indicating their overall test results and domain-level performance. NBCOT does not provide item-level feedback or answers to the individual questions contained in these practice tests.

Note: Once you submit the practice test for scoring, you will not be able to access the test again. You will only be able to view your feedback report.

To order a COTA practice test, candidates must log into their MyNBCOT account. Candidates who have not registered for an account will need to do so in order to access practice test purchase options.
