When DoD released the Interim Rule that implements CMMC (creating DFARS 252.204-7021) in September 2020, that opened CMMC up for a period of public comment. That public comment period closed at the end of 2020, and DoD has stated that they received many questions and comments. As of March 1, 2021, they are still adjudicating all of the comments. According to DoD’s comments during the February 22, 2021 CMMC-AB Town Hall, the current expectation is that the CMMC Assessment Guides will be published “hopefully by mid-year” [2021]. Changes to the CMMC Model are not expected to be released until closer to the end of calendar year 2021.
