Verified exam facts — both cohorts
Two separate exams under two rules, both with current versions effective June 1, 2026. Florida publishes no pass rate for either. Sources: the ADEX/CDCA vendor page, the 2026 ADEX Candidate Guide, and rules 64B5-2.013 and 64B5-2.0135, F.A.C.

Both exams: up to 5 of the items are unscored field-test questions, results are pass/fail only in 2-3 business days, each retake is the same full fee, registration credits expire 2 years from payment, and the ADEX 18-month completion window covers the clinical examination parts — not these exams.
