Once approved, the candidate will be eligible to attempt a total of four tests during a one-year approval period (initial test plus up to three retests). Only eligible tests for that individual will be available for them to take. The CBT application will not allow an individual access to a licensing test if he/she is not eligible to retest.

Candidates can retest once, immediately, if they fail the initial test, but must return on a separate day to attempt any additional of their 4 test attempts.
