Registering for the API-571 exam costs $440 USD at the official rate, and you need 70% / Scaled score determined by API to pass. Bear in mind that an unsuccessful attempt is not discounted the second time around — a retake is charged at the full fee again. That is why experienced candidates test themselves with the 151 practice questions from PrepAwayTest until their results are consistently strong before spending money on the real thing.

Yes, and we encourage it. A free PDF demo of the API-571 questions is available so you can evaluate the quality and layout before buying. After purchase, your material stays current with 365 days of free updates — and if that period ever expires, you can extend the update service at a 50% discount through your member zone.

Registration is handled through the vendor's official channels:

• API ICP Portal
• Prometric Scheduling

As for how you will sit it, the API-571 exam is offered Computer-based testing (CBT) at Prometric test centers; online proctored option available — pick the option that fits your situation during booking.

You will face 110 (100 scored, 10 unscored pretest) questions within a time allowance of 195 minutes. Raw numbers aside, the real skill is pacing: candidates who run out of time usually spent too long on early questions. Our advice is to set a mental per-question budget, skip and revisit anything that stalls you, and complete at least two full timed runs in the PrepAwayTest test engine before the real appointment so the clock never rattles you.

Both situations are covered.

The conditions are strict — an exam taken within 3 days of purchase does not qualify, the candidate's name must match the payer's, and free materials or expired orders are excluded.

Passing the API-571 exam earns you the Corrosion and Materials Professional certification, a Professional-level credential. It is the vendor's official proof that your skills meet the standard employers look for, and it regularly appears as a requirement in job postings. The certification also relates to API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector, so it can anchor a broader certification plan rather than stand alone.

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) Because vendors revise their eligibility rules from time to time, treat this as a starting point and verify the latest requirements on the official exam page — see the official API-571 exam outline before you commit to a test date.

The vendor organizes the API Corrosion and Materials Professional blueprint into 6 domains, led by Environmentally Assisted Cracking (25%), High-Temperature Corrosion and Degradation (15%), Uniform or Localized Loss of Thickness (25%). Every domain contains further subtopics, and the weighting tells you where your study hours pay off most — the full outline above has the complete picture, so review it before building your study plan.

The vendor recommends the following official courses for this exam:

• API RP 571 Damage Mechanisms Standard

Training builds knowledge, but it does not measure readiness. Once you finish a course, put yourself to the test with the API-571 practice questions from PrepAwayTest — that is where you find out whether the material actually stuck.
