The "Dismantle DEI Act of 2025" seeks to systematically dismantle Diversity, Equity, and Inclusion (DEI) practices throughout the Federal Government and entities receiving federal funds. Its core purpose is to ensure equal protection under the law by prohibiting specific DEI-related activities and ideologies, which it defines as "prohibited diversity, equity, or inclusion practices." This includes discriminating based on race, color, ethnicity, religion, biological sex, or national origin, and requiring training or assent to statements asserting that any such group is inherently superior, inferior, oppressive, or privileged.

The bill mandates the rescission of several executive orders and memoranda related to advancing equity and DEI within the federal workforce and communities. Federal agencies are required to close and wind up any programs or offices carrying out these rescinded orders, leading to appropriate reductions in force without reassigning affected employees. The Office of Personnel Management and the Office of Management and Budget must revise all their regulations, policies, and guidance to comply with the Act and rescind any materials previously adopted to implement the now-revoked executive orders.

A significant provision prohibits the use of federal funds for maintaining DEI offices, employing chief diversity officers, or developing and distributing DEI-related plans, reports, or training courses. This ban extends to training on critical theory, intersectionality, or sexual orientation/gender identity, and any training that asserts inherent group superiority or inferiority. However, the bill explicitly states that it does not prevent the maintenance and funding of historically organized Equal Employment Opportunity offices or offices enforcing the Americans with Disabilities Act.

The legislation also amends federal law to classify certain DEI-related requirements as prohibited personnel practices. Federal employees cannot be penalized in employment or performance appraisals for refusing to complete DEI training, critical theory training, or for not assenting to statements asserting inherent group superiority or inferiority. This aims to protect employees from adverse actions based on their participation or non-participation in such activities.

For federal contracting, grants, and cooperative agreements, the bill requires specific terms prohibiting contractors and recipients from engaging in "prohibited diversity, equity, or inclusion practices." It also bars the use of federal funds by these entities for maintaining DEI offices, employing chief diversity officers, or conducting DEI-related training. Similar prohibitions are extended to federal advisory committees, with provisions for termination of committees found to be engaging in prohibited DEI practices.

In the realm of education, the bill amends the Higher Education Act of 1965 to require accrediting agencies to confirm that their standards do not mandate or coerce institutions into engaging in prohibited DEI practices. It also prevents the Secretary of Education from using federal funds for DEI offices, officers, or related training. Furthermore, the bill repeals specific DEI-related programs and offices within various federal entities, including Fannie Mae, Freddie Mac, the Department of Defense, Department of Homeland Security, and financial regulators.

Finally, the Act establishes a private cause of action, allowing any person alleging a violation to bring a civil action in a United States District Court. Successful plaintiffs may be awarded various forms of relief, including writs of mandamus, monetary damages, attorney's fees, and litigation costs. A severability clause ensures that if any provision is found unconstitutional, the remainder of the Act remains in effect.
