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.
Every single individual that goes through the enlistment process should excel both mentally and physically. That is the number one principle that has consistently inspired this nation to serve these brave and honorable individuals with unwavering efforts. Those efforts officially came to the forefront when the country as a whole decided to correct perhaps the most significant enlistment related problem (passing the Armed Services Vocational Aptitude Battery test). Countless hours of hard work and dedication are currently reflected by the top-of-the-line ASVAB practice tests that this nation offers.
