POA&M. For purposes of achieving a Conditional CMMC Status, an OSA is only permitted to have a POA&M for select requirements scored as NOT MET during the CMMC assessment and only under the following conditions:
Level 1 self-assessment. A POA&M is not permitted at any time for Level 1 self-assessments.
Level 2 self-assessment and Level 2 certification assessment. An OSA is only permitted to achieve the CMMC Status of Conditional Level 2 (Self) or Conditional Level 2 (C3PAO), as appropriate, if all the following conditions are met:

POA&M closeout assessment. A POA&M closeout assessment is a CMMC assessment that assesses only the NOT MET requirements that were identified with POA&M in the initial assessment. The closing of a POA&M must be confirmed by a POA&M closeout assessment within 180-days of the Conditional CMMC Status Date. If the POA&M is not successfully closed out within the 180-day timeframe, the Conditional CMMC Status for the information system will expire.
Level 2 self-assessment. For a Level 2 self-assessment, the POA&M closeout self-assessment shall be performed by the OSA in the same manner as the initial self-assessment.
Level 2 certification assessment. For Level 2 certification assessment, the POA&M closeout certification assessment must be performed by an authorized or accredited C3PAO.
Level 3 certification assessment. For Level 3 certification assessment, DCMA DIBCAC will perform the POA&M closeout certification assessment.
