The 2017 Workplace and Equal Opportunity Survey of Active Duty Members (2017 WEOA) fulfills the Congressional mandate outlined in Title 10 USC §481 for a quadrennial survey to assess racial/ethnic relations in the military. The 2017 WEOA was the fourth active duty survey conducted to meet this statutory requirement. The survey was designed to assess self-reported experiences of and the climate surrounding racial/ethnic harassment and discrimination in the military. The 2017 WEOA included questions regarding Service members’ experiences of racial/ethnic harassment and discrimination in the 12 months before survey administration. It also included questions on members’ views of the effectiveness of DoD and Service-level trainings, policies, and programs to prevent and respond to incidents of racial/ethnic harassment and discrimination, as well as their perceptions of any progress the military and the nation have made in eliminating such incidents.
