ASVAB scoring is not as simple and straight forward as you might think. In fact, nothing about it is simple or straight forward. It is a good idea to understand the difference between the ASVAB AFQT and the ASVAB GT before you sit down for the exam.
The ASVAB is actually nine individual subtests covering a range of subjects. That’s why they call it a battery (Armed Services Vocational Aptitude Battery). Each subtest is scored individually and plays a different role in the ASVAB process. The ASVAB AFQT ( Armed Forces Qualification Test) is not another test, it’s the score of four subtest including Arithmetic Reasoning (AR), Mathematical Knowledge(MK), Word Knowledge (WK) and Paragraph Comprehension (PC). The ASVAB AFQT is your most important score because it is score they use to determine your enlistment qualification.
So the take away here is that those four subjects are the most important. In fact, your ASVAB AFQT score determines whether or not you qualify for any type of enlistment bonus, college plan or college repayment plan.
You will also come across the terms “raw score” , “standard score”, “percentile score” and “line score”. Again, these are all just scoring interpretations of the nine different subtests. Traditional tests scores are reported as a percentile which is the number of right answers divided by the total number of questions times 100. The ASVAB calculates it differently. The ASVAB percentile score is a comparison of your score in relation to everyone else score. The highest ASVAB score in terms of percentile is 99. This means you did better than 99% of the other people who took the test.
