The recruiters have a limit that they can allow in as well as a quota they strive to meet. There are only so many open slots for new recruits in any given time period. For instance, if you are an Air Force recruit and you have the AFQT score of 40. (Minimum Score allowed of 36). Had you scored a 35 or less the recruiter cannot accept you. A 40 means you meet the ASVAB standard, but if the Air Force has several other candidates well above the 70+ range (which they typically do) you are likely not competitive enough to get into the Air Force at this time.
For those who are interested in enlisting in the military, they are screened using the Armed Forces Qualification Test (AFQT), which is comprised of a subset of scores from the ASVAB. Successfully passing the AFQT is not the sole requirement for enlisting but is one of the qualifications that must be met. There are various requirements for the different branches of the military and those interested are encouraged to contact recruiters to obtain more information about requirements specific to that branch.

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.
