Air Force Reserve Citizen Airmen are selected every year to attend Developmental Education courses boarded through the Reserve School Selection Board (RSSB A&B), Reserve Developmental Education Designation Board (RDEDB), and Enlisted Developmental Education Board (EDEB). The boards are held quarterly over a five-day period at HQ Air Reserve Personnel Center, Buckley Air Force Base, CO, and attended by officer and enlisted senior leaders from a cross-section of the AF Reserve.
