At present, the API-571 exam's passing score is 70% / Scaled score determined by API, and registration costs $440 USD. Since failing means registering again at full price, thorough preparation is the economical choice — and API can revise both figures, so confirm them officially before booking.

The API Corrosion and Materials Professional blueprint is built around these main domains:

• Uniform or Localized Loss of Thickness (25%)
• Environmentally Assisted Cracking (25%)
• Mechanical and Metallurgical Failure Mechanisms (15%)

Additional domains appear in the full official outline — our bank covers them all.
