Air Force Enlisted Professional Military Education (EPME) is created and provided through the Thomas N. Barnes Center for Enlisted Education, named after the service's fourth Chief Master Sergeant of the Air Force, Thomas N. Barnes, the first African-American to attain the highest enlisted position in any branch of the U.S. Armed Forces. The principal instructional method for all Air Force EPME is guided discussion, in which students share ideas, experiences, and work together to achieve various educational objectives. Formative evaluations are an integral part of the curriculum and serve as feedback tools for the student and instructor. Summative objective and performance evaluations are used to determine whether the educational requirements outlined in the course are met. EPME courses include fitness and drill and ceremony components as well as formal lectures and academic research projects. Air Force EPME courses have been approved for college credit in the Leadership, Management & Military Science discipline of the service's Community College of the Air Force Associate in Applied Science degree programs. Mission: Provide the continuum of education necessary to inspire and develop enlisted leaders with the moral framework of integrity, service and excellence. Goal: Expand the leadership ability of enlisted leaders and strengthen their commitment to the profession of arms by integrating sound leadership, communication skills, and military studies principles and concepts throughout the continuum of education.
