Current program status — paused in Phase I

CMMC is currently paused in Phase I. The Department suspended the Phase II transition and later implementation milestones on , while a CMMC Reform Task Force conducts a 60-day review. No replacement Phase II date has been announced.

During the suspension, requiring activities may designate only Level 1 (Self) or Level 2 (Self) in new CMMC requirements. They may not issue new Level 2 (C3PAO) or Level 3 (DIBCAC) designations. Active solicitations containing those requirements are to be amended; existing contracts are to be modified. Contractors should obtain the actual written amendment or modification — not treat a press release as a substitute for their controlling instrument.

Phase I — November 10, 2025, continuing through the suspension

Phase I began when DFARS 252.204-7021 took effect on . During Phase I, DoD solicitations may include CMMC requirements at any permitted level. The primary active requirements are:

DFARS 252.204-7021 — Contractor Compliance with CMMC Level Requirement

The contract clause that operationalizes CMMC in DoD solicitations. Specifies the required Level, assessment type (self-assessment or C3PAO), and timing. Effective November 10, 2025.

What the suspension means for Level 2 contractors

During the suspension, new procurement designations for CUI contracts are limited to Level 2 (Self). The 110 NIST SP 800-171 Revision 2 requirements that underpin Level 2 remain the active baseline. Contractors handling CUI should continue self-assessment, SPRS posting, annual affirmation, and DFARS 252.204-7012 safeguarding work.

If a solicitation or existing contract already names Level 2 (C3PAO), contractors should look for a post-July 13 written amendment or modification. Do not assume the announcement alone rewrote the instrument. See the full Phase II suspension explainer.
