All IADA members must successfully pass a comprehensive background investigation and on-site review. Investigative screening verifies education/training, work experience, financial responsibility, past or present criminal activity, existence of conflicts of interest, and client service satisfaction. The on-site review focuses on the applicant's automotive damage assessment and administrative skills.

There are several requirements mandated to maintain membership in the organization, including abiding by its Code of Ethics and Bylaws, compliance with the 20-point Appraisal Program, Service Time Standards, and attending one of three yearly IADA educational functions.
