Key Takeaways

  • Contractors failing a CMMC assessment may receive Conditional CMMC Status if at least 80% of controls are met, requiring a Plan of Action and Milestones (POA&M) for full compliance.
  • All POA&M deficiencies must be resolved within 180 days, followed by a closeout assessment to obtain Final CMMC Certification.
  • Failure to close out POA&M deficiencies within the deadline results in certification expiration, contract ineligibility, and possible termination.

What Happens If a Contractor Fails an Assessment?

When a contractor undergoes a CMMC assessment (learn more about the formal assessment process) but does not fully meet the required cybersecurity controls for their designated level, several steps follow.

1. Assessment Results & Reporting

  • Assessment results are documented and reported in the Supplier Performance Risk System (SPRS) or the CMMC Enterprise Mission Assurance Support Service (eMASS).
  • If deficiencies exist, the contractor will not receive unconditional certification but may qualify for Conditional CMMC Status (if applicable).

2. Conditional CMMC Status (For Level 2 & Level 3 Assessments)

  • Contractors meeting at least 80% of the required security controls but lacking some implementations can be granted Conditional CMMC Status.
  • A Plan of Action and Milestones (POA&M) must be created to address deficiencies.
  • All deficiencies must be corrected within 180 days to achieve Final CMMC Status.

3. POA&M Closeout Assessment

  • After implementing corrective actions, the contractor undergoes a POA&M closeout assessment.
  • If all requirements are met, they receive Final CMMC Certification for their required level.
  • If deficiencies remain after 180 days, the Conditional CMMC Status expires, and standard contractual remedies apply, potentially resulting in loss of contract eligibility.

4. Failure to Meet Compliance Within 180 Days

  • If a contractor fails to close out POA&M deficiencies within 180 days, their CMMC certification is revoked.
  • The contractor becomes ineligible for contract awards and may face termination if they fail to meet DFARS cybersecurity requirements.
  • DoD may take standard contractual remedies, such as non-renewal or enforcement actions.

What is a POA&M?

A Plan of Action and Milestones (POA&M) is a structured plan outlining:

  • Unmet security requirements from the CMMC assessment.
  • Mitigation strategies for each deficiency.
  • Milestones and deadlines to close security gaps.
  • Resources needed to achieve compliance.

When is a POA&M Required?

  • If an organization fails to meet all CMMC security controls but still meets at least 80%.
  • Only certain requirements can be placed on a POA&M; some critical security controls must be met upfront.

Key POA&M Requirements

1. Must be Closed Within 180 Days

  • Contractors must remediate all POA&M items within 180 days of receiving Conditional CMMC Status.
  • Failure results in loss of Conditional CMMC Status.

2. Second Assessment for Verification

  • A POA&M closeout assessment must be conducted to validate the implementation of pending security requirements.

3. Tracking & Reporting

  • POA&M progress is tracked and reported in SPRS/eMASS.

4. Conditional Status Expiration Consequences

  • If the POA&M closeout assessment fails, contractual penalties may apply, including contract ineligibility.

Summary of Non-Compliance Handling

ScenarioOutcome
Contractor passes the assessmentReceives Final CMMC Status
Contractor meets 80% but has deficienciesReceives Conditional CMMC Status with POA&M
Contractor fails to close out POA&M items in 180 daysAchieves Final CMMC Certification
Contractor passes POA&M closeout assessmentLevel 1 (Self) for FCI, Level 2 (C3PAO) for CUI
Contractor completely fails the assessmentNot eligible for contract award

This process ensures contractors have a structured path to compliance while enforcing strict cybersecurity requirements to protect Controlled Unclassified Information (CUI).
