The Armed Services Vocational Aptitude Battery (ASVAB test--also known as the AFQT (Armed Forces Qualification Test). This is the score used by the recruiter to determine a potential recruit’s enlistment eligibility, assign a recruit to a military jobs, and aid students in career exploration. The AFQT is actually a subset of the ASVAB - only with scores of four of the ten test sections calculated.
Composite Scores are sometimes referred to as “line scores”, “aptitude area scores”, or “MOS scores”. These scores are derived by adding different combinations of the sub test standard scores. Composite scores are used by the different branches of the U.S. Armed Services to determine which military jobs (or Military Occupational Specialities/MOS) may be the best fit for you. These composite scores are only one factor in determining which military job is right for you. The recruiter will also use job availability, physical and medical qualifications, and eligibility for security clearance as additional factors. Each branch of the service also defines their own composite scores and eligibility requirements. Some of these definitions and requirements are shown below:
Technical, Clerical, Combat, Electronics Repair, Field Artillery, General Maintenance, Mechanical Maintenance, Operators/Food, Surveillance/Communication Skilled Technician	Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Mathematics Knowledge (MK). General Science (GS), Electronics Information (EI), Auto Information (AI), Shop Information (SI), Mechanical Comprehension (MC), Assembling Objects (AO)	Weighted combinations of all ASVAB Subtests

Tenga en cuenta que los MEPS es operado por los militares, por lo que no tiene mucho sentido del humor cuando se trata de los códigos de vestimenta. Vestir de manera conservadora. No use ropa con agujeros en ellos o malas palabras escritas en ellas. Asegúrese de que su ropa interior no se muestra. Dejar su sombrero en casa porque, bajo el código de vestimenta civil y militar, no se puede usar sombreros en interiores.

After a candidate has completed the ASVAB they must wait one calendar month before retaking the exam. An additional calendar month must pass before retesting a second time. Six calendar months must pass before retaking the test a third time. The scores received from the ASVAB may be used for enlistment for up to two years from the initial test date. 
Don’t be fooled by the appearance of the low numbers, the algorithm that computes the AFQT is very sophisticated. Just because your ASVAB score is 40 doesn’t mean that you only got 40% of the questions correct, it could simply mean that you lack strength in one area, but succeed with high praise in another. Your ASVAB score is only a means by which you are categorized for available positions; it is by no means a measure of intelligence.
The various armed forces adopted all of those aspects in 1976. At that point in time, the test was in its written form rather than today’s more common form (computerized test format). The written form covers all of the previously mentioned areas as well, which is why both forms are still available. All-in-all that answers the question concerning the intention of the test.
