The API-571 exam is API's path to the ICP Programs certification, a credential at the Professional level. It confirms you can apply the API Corrosion and Materials Professional objectives in realistic scenarios — the kind of proof that changes job conversations. It also connects to a wider certification family covering API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector, so the effort keeps compounding. It's easier to want than to earn, which is exactly why structured practice beats good intentions.

The API Corrosion and Materials Professional blueprint centers on Damage Mechanisms. The full topic list is in the exam topics section above.

The API Corrosion and Materials Professional exam packs 100 questions into 3.5 hours (210 minutes). Convert that into a tempo before test day: minutes divided by questions is your per-item budget, and anything burning double its budget gets flagged and revisited at the end. Rehearse the tempo against a real timer — every ActualVCE engine session enforces one — until finishing with review time to spare feels routine.

Passing API Corrosion and Materials Professional requires Minimum passing score determined by API using the modified Angoff method (typically around 70%), and each attempt costs $900 USD (exam fee through API) — retakes included, at full price. The sound strategy is arriving over-prepared: drill with ActualVCE practice questions until your timed scores clear the mark across several consecutive sessions, then register. Over-preparation is cheaper than re-registration.

API lists the API Corrosion and Materials Professional question formats as: Multiple Choice. Formats shape tactics — find the actual question sentence inside long scenario stems before reading the rest, and re-verify every selection on multi-answer items. ActualVCE's 151 practice questions drill these formats until only the content feels new on exam day.
