What are the types of API Examination Questions?

Understanding the different types of questions used in API certification examinations is essential for developing an effective study strategy.

Open-Book and Closed-Book Examinations

The core API inspector certifications include both closed-book and open-book sections:

• API 510 – Pressure Vessel Inspector
• API 570 – Piping Inspector
• API 653 – Aboveground Storage Tank Inspector
• API 1169 – Pipeline Construction Inspector

The following certifications are entirely closed-book:

• API 571 – Corrosion and Materials
• API 577 – Welding Inspection
• API 580 – Risk-Based Inspection
• API SIFE – Source Inspector Fixed Equipment
• API SIRE – Source Inspector Rotating Equipment

Closed-Book Questions

Closed-book questions assess the knowledge that inspectors are expected to know without referring to the codes or standards. These questions typically evaluate your understanding of fundamental inspection principles and your familiarity with important code requirements.

Examples include:

• Basic code requirements
• Important definitions
• Mandatory “Do” and “Do Not” requirements
• Numerical limits and acceptance criteria
• Well-established inspection principles
• Short, clear, and definitive statements taken directly from the codes

Whenever you encounter a concise, quantitative, or mandatory statement within a code, there is a good chance it could form the basis of a closed-book examination question.

Open-Book Questions

Open-book questions require candidates to consult the applicable code during the examination.

These questions typically involve:

• Calculations
• Tables and charts
• Graphs and diagrams
• Formulas
• Detailed code requirements
• Longer descriptive paragraphs

In the open-book section, success depends less on memorizing information and more on knowing where to find it quickly within the reference documents.
