ASVAB Score - Air Force recruits must score at least 36 points the 99-point ASVAB (Note: The "Overall" ASVAB Score is known as the "AFQT Score," or "Armed Forces Qualification Test Score"). Exceptions are made, however, for a handful of high school graduates who can score as low as 31. In actuality, the vast majority (over 70 percent) of those accepted for an Air Force enlistment score 50 or above.
Education - You're more likely to be struck by lightning than enlist in the Air Force without a high school diploma. Even with a GED, the chances are not good. Only about 1/2 of a percent of all Air Force enlistments each year are GED-Holders. To even be considered for one of these very few slots, a GED-holder must score a minimum of 65 on the AFQT. The Air Force allows a higher enlistment rank for recruits with college credit.
ASVAB Score - The Army requires a minimum AFQT Score of 31 to qualify for enlistment. However, in recent months, the Army has been approving more and more waivers for those with scores as low as 26 (Category IVA). To qualify for certain enlistment incentives, such as enlistment bonuses, an Army recruit must score a minimum of 50.
Education - The Army allows more recruits to enlist with a GED than any other branch. In Fiscal Year 2008, only 83 percent of new Army recruits had a high school diploma (or at least 15 college credits), comparted with the Department of Defense (DOD) average of 92 percent. The Army even has a special program, called Army Prep School, that allows individuals to enlist who have no high school diploma or GED.
Like the Air Force, the Army also offers a higher enlistment rank for recruits with college. Unlike the Air Force, where the maximum initial enlistment rank for college credits is E-3, the Army offers the rank of E-4 for those with a bachelors degree.
