CCDV-F retake cost & waiting period calculator
The exact earliest date you can retake Claude Certified Developer, plus the fee and how many attempts you have left. Waiting periods and limits come from the sourced exam facts.
Heads up:
Retake policy: Claude Certified Developer allows 4 attempts per rolling 12-month window, with the wait after a fail growing
with each attempt (14 days then 30 days then 90 days).
Full exam fee each attempt - no discount for retakes.. Last checked 2026-09-13 -
see the evidence page. Do not assume another exam's rules apply here;
retake policy differs sharply by vendor and this calculator only encodes CCDV-F's own rules.
