Gather all training documents. Any certificate received can count as certified training, so don't exclude anything. Basic training and technical or specialty training can even count as credit.
Visit the American Council on Education website to see if any courses you have taken qualify as credit. Although the exact title of your completed course may not be listed, it may be equivalent to a similarly titled course.
Bring certificates to the local base education office. Ask if any completed training is convertible to military college credit. For example, completing the Air Force's Airman Leadership School can count toward credit for a degree from the Community College of the Air Force (CCAF).
Log online and search for military friendly schools, such as ones that advertise accepting military credits or have counselors that specialize in helping military members register. See if they consider credits for Professional Military Education. Schools such as American Military University will examine PME transcripts before awarding any credit toward graduation requirements. Some traditional schools also have military and veteran specialists, so don't completely exclude them.
Contact the admissions counselor of the school you are most interested in. Inquire about how to send proof of your military experience as transferable college credits. Be advised that many schools outside of the military will only accept a limited amount of transferable credit hours.
