Start by submitting your Joint Services Transcript (or CCAF Transcript for Air Force-related credit) to the college or university you are considering.
Keep in mind different schools have different policies when it comes to evaluating and accepting non-traditional credit. American Council on Education (ACE) evaluates military courses and occupations and recommends semester-hour credit based on alignment with civilian educational standards. ACE credit recommendations are captured on the Service member's JST.
