While scoring the evidence for a particular CMMC practice, the Certified Assessor notes that one of the practice objectives is NOT MET, thereby scoring the entire practice as NOT MET. The OSC Assessment Official disagrees with the Certified Assessor's decision, and they both take the dispute to the Lead Assessor, who is unable to resolve the issue to the OSC's satisfaction.
How will this dispute be settled?
The CMMC Assessment Process (CAP) specifies that when disputes cannot be resolved by the Lead Assessor, they must be elevated to the C3PAO Official, who has authority to make the final decision.
Extract:
''Unresolved disputes between the OSC and the Assessment Team must be elevated to the C3PAO Official for final resolution.''
Therefore, the C3PAO Official is the final arbiter in such disputes.
