NAVY ASVAB line scores play an important role in the rating (or job) that a Sailor can have while in the Navy. Line scores are the scores that are given to each of the nine sub-tests in the ASVAB, or The Armed Services Vocational Aptitude Battery (ASVAB).

There are nine parts to the test:

* General Science (GS)

* Arithmetic Reasoning (AR)

* Word Knowledge (WK)

* Paragraph Comprehension (PC)

* Mathematics Knowledge (MK)

* Electronics Information (EI)

* Auto Shop (AS)

* Mechanical Comprehension (MC)

* Assembling Objects (AO)

The score for each of these subtests is called a line score.

Jobs in the Navy are called ratings, and eligibility for a rating is largely determined by the line scores of the ASVAB.

For example, in order to qualify to be a Gunner’s Mate (GM), the combined scores of Arithmetic Reasoning, Mathematics Knowledge, Electronics Information, and General Science must equal 205. Or, as the NAVY writes it: AR+MK+EI+GS=205

Some ratings have two different ways to qualify. In order to sign a contract to be an Engineman (EN) a recruit can either have VE+AR+MK+AS=200 OR VE+AR+MK+AO=205.

It is important to note that the Navy ASVAB line scores aren’t the only pre-requisite for a rating. There are other considerations, such as vision, citizenship, and ability to obtain a security clearance.

ASVAB line scores are often confused with the AFQT, which is a score derived from certain line scores. The scores from Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Word Knowledge (WK), and Paragraph Comprehension (PC) are used to compute the AFQT like this: The WK and PC scores are added together and used to determine a VE (Verbal Expression) score. Then the VE score is doubled, and the sum added to the AR and MK. The sum of 2VE + AR + MK is the raw score. The AFQT percentile score tells how good one score is in comparison to all the other scores submitted. A 59 means that the test taker scored better than 59% of those tested.

Most of the time when someone tells their ASVAB score, they really mean their AFQT percentile. The AFQT is often confused with Navy ASVAB Line Scores .
