With a total score of 38 on the ASVAB, a service member would qualify for one of three US Navy ratings (jobs): a musician, boatswain's mate or draftsman. Armed Services Vocational Aptitude Battery is a timed multi-aptitude test designed, developed and maintained by the Department of Defense.
The ASVAB measures your strengths, weaknesses and potential for future success across multiple areas, according to Military Advantage. ASVAB test scores are broken down by the individual sub-tests and composites of the sub-tests.
The Navy considers how you score on specific ASVAB sub-tests to see which jobs you qualify for. The ASVAB sub-tests are general science (GS), arithmetic reasoning (AR), word knowledge (WK), paragraph comprehension (PC), numerical operations (NO), coding speed (CS), auto and shop information (AS), mathematics Knowledge (MK), mechanical comprehension (MC), electronics information (EI), and sum of word knowledge and paragraph comprehension (VE). For example VE+AR=89 would qualify someone to serve as a mess specialist.
All published jobs that have specific ASVAB requirements currently have minimum total scores of greater than 89 (the Mess Specialist). The musician, boatswain's mate and draftsman all currently do not have published required ASVAB scores. This means that anyone qualifies for these ratings and can potentially serve in the US Navy in these capacities.
