Entrance test scores. When you apply to join the Air Force as an enlisted Airman, you will take the Armed Services Vocational Aptitude Battery (ASVAB) entrance exam. High school seniors or graduates must achieve a 36 AFQT (overall score) as the minimum qualifying score. GED holders must achieve a 65 AFQT.
Fundamental Requirements. Army enlistment guidelines stipulate that you must be between the ages of 17 and 34, with at least a high school diploma. However, joining prior to age 18 requires consent from a parent or legal guardian. You must be in good physical health and pass a series of test to prove it.
