Collect all course completion certificates or transcripts for all schools and courses you attended during military service. Consider the American Council on Education's military guidelines as a recommendation reference for what is typically considered. If you can't find certain ones, consider contacting the respective institution or your military installation's education office to see if you can get copies.
Look for schools with military affiliations. You can check online for schools that advertise military credit acceptance. The Military Friendly Schools website allows you to search for such schools by degree, school name and state location.
Contact the school admissions programs to see what courses they generally accept for credit transfer. Refer to the council's guidelines if you feel that a course you attended may be acceptable but is known under a different name. Inquire about transfer limits and what course requirements will be satisfied upon transfer.
Browse through the school's curriculum guide to see where your transferred credits may be applied. Consider degree programs where your transferred credits will reduce the most graduation requirement courses.
