Starting November 10, 2025, Department policy requires program managers to include CMMC requirements in solicitations. Whether a Level 2 self-assessment or independent (C3PAO) assessment is required depends on the program's criticality and the nature of the CUI involved, as determined by the requiring activity.

In-Depth Analysis

Self-Assessment vs C3PAO: How It's Determined

Not all Level 2 requirements demand a third-party assessment. The decision depends on the sensitivity and criticality of the CUI involved.

Level 2 Self-Assessment

Applicable when the CUI involved is less sensitive and the program risk is lower. You assess yourself against all 110 NIST SP 800-171 requirements and enter your score in SPRS.

Level 2 C3PAO (Independent) Assessment

Required when the CUI is more sensitive or the program is deemed critical. An authorized C3PAO conducts the assessment and issues your certification.

Who Decides?

The requiring activity (typically the program manager and contracting officer) determines whether self or independent assessment is needed based on:

  • The sensitivity of the CUI involved
  • Program criticality to national security
  • Risk assessment by the requiring activity

The specific requirement will be stated in the solicitation. Beginning November 2026 (Phase 2), C3PAO assessments become available and will be required in more solicitations.
