Understanding Evidence Sufficiency in CMMC Level 2 AssessmentsDuring aCMMC Level 2 Assessment, theLead Assessormust determine whether the evidence collected for each practice issufficientto support an assessment finding. This aligns with theCMMC Assessment Process (CAP) Guide, which requires assessors to evaluate:
Examinations– Reviewing documents, configurations, and system records.

Can be independently verified.
