The Defense Equal Opportunity Management Institute (DEOMI) is a U.S. Department of Defense joint services school and research laboratory located at Patrick Space Force Base, Florida, offering both resident and off-site courses, and working in areas of equal opportunity, intercultural communication, religious, racial, gender, and ethnic diversity and pluralism.

Courses and research are meant to support the readiness of civilian and military personnel working with the American armed forces.

DEOMI was established in 1971 as the Defense Race Relations Institute (DRRI) based on lessons learned from the Civil Rights Movement.

Chaired by Air Force Major General Lucius Theus, the task force resulted in Department of Defense Directive 1322.11, establishing the Race Relations Education Board, and led to the 1971 establishment of the DRRI at Patrick AFB, Florida, under the leadership of the first director, Col. Edward F. Krise, USA.

[1] More than 20,000 reserve and active duty military members and civilian employees of the American armed forces have graduated from DEOMI since its creation.

[11] In 2011, Dr. Daniel P. McDonald and his team began to develop a capability for DEOCS that went beyond merely providing a near real-time survey service for commanders, and began to develop a continuous performance support and improvement system around the assessment capability called the 'Assessment to Solutions' system.

[8] The concept is that commanders and their equal opportunity advisors or command climate specialists need real-time support not only in carrying out the complex task of a complete climate assessment to detect issues before they evolve, but also should be presented with evidence-based solutions to meet their unique diagnosed needs within their organizations.
