The CMMC Assessment Process (CAP) provides a formal, structured mechanism for an Organization Seeking Certification (OSC) to contest assessment results. If an OSC Assessment Official disagrees with a "NOT MET" finding presented during the Final Findings Briefing, their official recourse is to initiate the Assessment Appeals Process. This process requires the OSC to submit a formal written appeal to the C3PAO within a specified timeframe. This ensures that disputes over evidence interpretation or requirement application are handled consistently and fairly, maintaining the integrity and objectivity of the CMMC assessment framework.

A. Request an immediate reassessment by the same Assessment Team. This is incorrect because the appeals process, not an immediate reassessment, is the designated procedure for challenging the interpretation of evidence for a specific finding.
C. Demand that the Lead Assessor revise the finding based on their explanation. This is incorrect as an OSC cannot "demand" a change. The Lead Assessor's professional judgment is independent, and disputes must be resolved through the formal appeals channel.
D. Reapply for a new assessment with a different C3PAO. This is a business decision to abandon the current assessment, not the procedural recourse for disputing a specific finding within the established CMMC Assessment Process.

1. The Cyber AB. (2022). CMMC Assessment Process (CAP) for CMMC Level 2, Version 1.1. Section 6.4, "Assessment Appeals Process," p. 23. This section explicitly states, "The OSC may appeal a finding of 'NOT MET' for any practice or process... The OSC must submit the appeal in writing to the C3PAO within 10 business days of the Final Findings Briefing."

2. Carnegie Mellon University Software Engineering Institute (SEI). (2021). CMMC v1.02 Assessment Guide Level 3. While an older version, the principle of a structured process for findings is established. The formalization of the appeals process in the CAP is the evolution of ensuring fairness and due process, a concept central to SEI's appraisal and assessment methodologies. The CAP supersedes this for procedural specifics.
