What is the purpose of pilot questions in the CIRO exam?

Pilot questions in the CIRO exam are used to gather data for future exams. These questions are included in the test but do not count toward the candidates' scores. Their primary purpose is to evaluate how the questions perform in terms of difficulty and discrimination between different levels of knowledge among candidates. By analyzing how students respond to these questions, the exam creators can refine future tests to ensure they effectively measure the necessary competencies for industrial refrigeration operators.

The pilot questions serve a vital role in maintaining the exam's quality and relevance over time, which ultimately benefits both future candidates and the industry by ensuring a reliable assessment of skills and knowledge.
