Program Regulations

On August 28th, 2025, DOER filed final regulations for the SMART 3.0 Program with the Secretary of State's Office, under 225 CMR 28.00. (See summary of program changes.) DOER also made a single redline edit to the existing regulation, 225 CMR 20.00.

DOER further updated 225 CMR 28.00 to align with Secretary of State formatting requirements. The updates modify the citations for certain provisions but do not make any substantive changes from the version published on DOER’s website on August 29, 2025.
