# CMMC Program Defines Assessor Requirements

A guide checked October 29, 2026, outlines the qualifications for becoming a Certified CMMC Assessor (CCA), the credential for personnel conducting CMMC Level 2 assessments within C3PAOs. Candidates need an active CCP, a DoD 8140-listed certification, approved CCA training, documented experience, a passed exam, and a Tier 3 determination. The exam costs $575 for ISACA members or $760 for non-members, plus a $50 application fee.

- C3PAOs can use these criteria to plan assessor hiring and training for Level 2 assessment work; contractors can account for assessor capacity when planning CMMC assessment readiness.
- Organizations evaluating assessor development costs should include the exam and application fees alongside training and experience requirements.
