What to Know About the API-571 Exam and Our Services
According to the latest exam information, the API-571 exam contains 110 (100 scored, 10 unscored pretest) questions and runs for 195 minutes minutes. Simulating that exact limit in practice builds the pacing a tough exam demands.
The API Corrosion and Materials Professional blueprint centers on these domains:
- Other Damage Mechanisms (15%)
- Terms, Definitions, and Acronyms (5%)
- Environmentally Assisted Cracking (25%)
Further domains complete the official outline — the question bank covers every one.
Registration goes through the official channels below:

Compared with training institutions, the bank is affordable and self-paced; compared with guesswork, it is systematic. Download the free demo first, and if anything goes wrong — even a simple downloading problem — 24/7 customer assistance is one message away.
API lists these official training options for candidates:
Structured training plus consistent self-practice covers both depth and exam readiness.
API states the following prerequisites for the API Corrosion and Materials Professional: 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).
Confirm the current requirements on the official certification page before you register.
Currently, the API-571 exam requires a passing score of 70% / Scaled score determined by API, with a registration fee of $440 USD. API sets both figures, so verify the latest on the official site before scheduling.
Upon successful payment, our system automatically sends the product to your mailbox — typically within about a minute — with an instant download link on screen. If nothing arrives within two hours, check your spam folder and contact our 24/7 customer assistance. Updates are free for 365 days: the moment a new version releases, the latest bank is sent to your email immediately, no matter when you purchased. A 50% renewal discount applies when the period ends.
