Informational only — not financial or career advice. Exam fees and certification requirements change, and the figures here are accurate only as of the listed verification date. Confirm the current fee and rules directly with the certifying body before you register or budget. We report the official-body exam fee for a single attempt; it excludes prep courses, materials and retakes, and is not the total cost of certifying.
