In the context of the Cybersecurity Maturity Model Certification (CMMC) 2.0, achieving Level 2 compliance requires an Organization Seeking Certification (OSC) to implement all 110 security practices outlined in NIST SP 800-171 Revision 2. The CMMC framework allows for a limited use of Plans of Action and Milestones (POA&Ms) to address certain deficiencies; however, this is contingent upon meeting specific criteria.

According to the final CMMC rule, to obtain a Conditional Level 2 status, an OSC must achieve a minimum score of 88 out of 110 points during the assessment. This scoring system assigns weighted values to each of the 110 security requirements, with some controls deemed critical and others non-critical. The POA&M mechanism permits OSCs to temporarily address non-critical deficiencies, provided the minimum score threshold is met. Critical controls, however, must be fully implemented at the time of assessment; they cannot be deferred and included in a POA&M.

In the scenario where 15 practices are NOT MET, the OSC's score would fall below the required 88-point threshold, rendering the organization ineligible for Conditional Level 2 status. Consequently, the OSC would not have the option to remediate these deficiencies through a POA&M. Instead, the organization must fully implement and rectify all NOT MET practices before undergoing a subsequent assessment to achieve the necessary compliance level.

This policy ensures that organizations handling Controlled Unclassified Information (CUI) have adequately addressed all critical and non-critical security requirements, thereby maintaining the integrity and security of sensitive information within the Defense Industrial Base.

For detailed guidance on assessment criteria and the use of POA&Ms, refer to the CMMC Assessment Guide – Level 2 and the official CMMC documentation provided by the Department of Defense.
