Many high schools give students the opportunity to take the ASVAB as part of career exploration. If you chose not to take one in high school, then you will have to schedule a time to take it. You can contact the Armed Forces Recruiting Officer in your area and you can schedule an appointment with a local recruiter from the branch of the military you wish to join.

The ASVAB (Armed Services Vocational Aptitude Battery) is a timed multi-aptitude test developed and maintained by the Department of Defense. The test is given at more than 13,000 schools and Military Entrance Processing Stations nationwide and is used to determine the branch of service and career field where a candidate would most excel. If you’re one of the more than one million people a year preparing to take the test, this is your one-stop resource to ensure you perform your very best.

The ASVAB is one of the most widely used aptitude tests in the world. The intent of the ASVAB test battery is to assess a candidate's potential for future success in the U.S. Military. Because of the nature of the test, the ASVAB can also be used to give a candidate valuable information about both military and civilian career choices that they may be suited for.

We took the diagnostic tests (all of them) and found so many errors it was appalling. For many of the arithmetic reasoning questions, the correct answer is not even listed, and when you look at the answer explanations, they are very odd. One told me that from 6:30 am to 11:15 am is five hours. Last time I checked, that's 4 hours and 45 minutes. The paragraph comprehension sections always have issues, and the word knowledge is ridiculous.

It is critical to know how ASVAB scores are calculated and what they are used for.  The Armed Services Vocational Aptitude Battery (ASVAB) tests are used to identify whether a candidate is qualified to enlist in a particular branch of the U.S. Military.  The ASVAB test is also used to determine which military jobs (referred to as MOS for Military Occupational Specialties) a candidate is best suited for.  ASVAB scores can also be used by test takers to help explore which careers they may be a good fit for them – whether they go into the military or not. While no one officially passes or fails the ASVAB, each branch of the military has specific minimum scores required for enlistment.  Your scores also affect the type of military job, enlistment bonuses and salary you are eligible for.
Las naciones son unidades políticas y militares, pero no son necesariamente las unidades más importantes de la vida económica, ni son muy parecidas en un sentido económico. Lo que realmente tienen en común todas las naciones es el hecho político de su soberanía. Es más, la imposibilidad de los gobiernos nacionales de controlar las fuerzas económicas sugiere que las naciones son irrelevantes en la promoción del éxito económico.
The content of the test has been clearly laid out, but there is still a ton of information concerning the actual place where the test is administered and the time that is allocated for each section. The computerized test is administered in a “military entrance processing station” (MEP) or a satellite region that is identified as a “military entrance tests site” (MET). The difference in the two locations is that the METs are the places that are responsible for administering the written test, while MEPs are the places that administer the computerized tests.
