In a profession where the quality of practitioner competence directly affects the fairness and validity of talent decisions, certification is not a box-ticking exercise. It is a statement of commitment to the highest professional standards.
What the COA Covers
The Certified Occupational Assessor (COA) programme covers five competency areas: assessment design, delivery and observation, scoring and evidence, feedback and reporting, and professional ethics. Each area is grounded in current research and aligned to IAOA’s global standards framework.
Who Should Pursue It
The COA is designed for practicing assessors who already hold foundational knowledge of occupational assessment. It is particularly valuable for HR professionals who run assessment centres, occupational psychologists looking for formal recognition of their assessment competence, and L&D practitioners building internal assessment capability.
What It Unlocks
Beyond the credential itself, COA holders gain access to the IAOA professional community, discounts on future IOA programmes, eligibility to supervise and mentor trainee assessors, and recognition as a senior practitioner by IAOA member organisations worldwide.
