How the API 653 exam questions developed?

A question writing session is periodically conducted by Subject Matter Experts (SME’s), or individuals who specialize in pressure vessels, write questions from specific sections of the Code. Each question is then checked by three other SME’s.



This validation exercise answers two questions;

Is the question written clearly?
Does the question cover knowledge that is important to a vessel inspector?
These questions then go into a question data-bank as non scored exam questions.



Presently there are over 1000 questions in the data-bank and are grouped by topics. For each examination, there are 170 questions on the exam pulled from Area of Examination (see below). Only 140 Questions are scored. The remaining 30 are pre-test questions and not marked towards your score, that is, these pre-test questions do not affect your score whether you have answered them correctly or not. API does not tell you which ones these questions are.

API needs to ensure that these questions are not significantly challenged by the candidates and have also been answered by a reasonable number of candidates before adding them to their question bank as scored questions.
