The API-571 exam — full title Corrosion and Materials Professional — is API's own certification test, and passing it awards the ICP Programs certification at the Professional level. The certificate is valuable precisely because it is demanding: it proves to employers that your skills survived a vendor-built examination. It also serves as a stepping stone toward API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector.

The passing score is Minimum passing score determined by API using the modified Angoff method (typically around 70%), and the official registration fee is $900 USD (exam fee through API). Note that the fee pays for a single attempt — a retake is charged at full price again, which is the expensive way to discover weak spots. The cheaper discovery method is self-testing: drill 151 practice questions at Actual4Labs in timed mode until your scores clear the passing mark with room to spare, then register.
