After what’s the average ASVAB score?, the second most asked question about the ASVAB is “what’s the highest possible score on the ASVAB test?”
Because the AFQT score (what’s typically referred to as the ASVAB score) is converted to a percentile score between 1 and 99, the highest score possible is a 99. Getting a 99 means you did better on the test than 99 percent of all the potential recruits who took the test.
But, because of the way the AFQT score is computed, getting the maximum score doesn’t necessarily mean that you have to ace each of the subtests that go into it so although 99 is the highest possible score that doesn’t mean it’s necessarily a “perfect” score.
Of course your overall ASVAB score is important but, after getting the minimum score necessary to enlist and/or qualify for any enlistment bonuses, it’s your performance on the subtests that make up the line scores for the military job you want that actually make the most difference.
