The API-571 exam is the official exam behind the Corrosion and Materials Professional credential from API. It sits at the Professional level of the API certification track. It is also associated with API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector. The PrepAwayETE practice questions on this page map to the same objectives, so you can measure your readiness before you book a seat.

The API-571 exam contains 110 (100 scored, 10 unscored pretest) questions and gives you 195 minutes to complete them. That pace leaves little room for getting stuck, so train yourself to flag a hard question, move on, and circle back later. Run at least one full timed session in the PrepAwayETE test engine a week before your exam date to check whether your pacing holds under pressure.

You need 70% / Scaled score determined by API to pass the API-571 exam, and the official registration fee is $440 USD. A retake means paying that fee again in full, which makes thorough preparation the cheaper option by far. Before scheduling, take a timed PrepAwayETE practice test; if you are not scoring comfortably above the passing line, give yourself more study time instead of booking on hope.

Hold current API 510, 570 or 653 certification; or meet education + experience requirements: BS/BS in engineering/tech + 1 year, 2-year degree + 2 years, high school + 3 years industry experience (past 10 years)

Requirements can change, so confirm the latest details on the official API exam page before you register.
