In the 1950s, the military adopted a single exam known as the Armed Forces Qualification Test (AFQT). Used as a screening tool, the AFQT measured a recruit’s ability to absorb military training and their future potential. It was supplemented by service-specific battery tests for the purposes of MOS classification. In 1972, the Department of Defense determined that all services should use one exam for screening and assigning individuals to an MOS. The AFQT was phased out over a two-year period in favor of the current Armed Services Vocational Aptitude Battery (ASVAB) test.
Los puntajes de AFQT se agrupan en cinco categorías principales según los rangos de puntaje percentil. Las categorías III y IV se dividen en subgrupos porque los servicios a veces usan esta tabla para fines de seguimiento interno, límites de alistamiento e incentivos de alistamiento. En función de sus puntajes, el ejército decide qué tan entrenable puede ser para realizar trabajos en el servicio.
The ASVAB test can be taken at your school or a MEPS (Military Entrance Processing Stations) or MET (Mobile Examination Test) sites.  When the ASVAB is administered at your school, it is usually part of the Student Testing Program or Career Exploration Program.  When the ASVAB is given at MEPS or MET sites, it is part of the Enlistment Testing Program.  The ASVAB test content is the same no matter where you take it, except that you will not have to take the Assembling Objects test if you take the test at your school (as part of the Student Testing Program).  When you take the test in the Student Testing Program you will receive three composite scores (Verbal Skills, Math Skills, and Science and Technical Skills).  When you take the ASVAB as part of the Enlistment Testing Program, you will receive an AFQT (Armed Forces Qualification Test) score and Service composite scores.  These scores are used for assigning your military job.
A diferencia de la versión de lápiz y papel, no se puede saltar preguntas o cambiar sus respuestas después de que los introduzca en la prueba CAT-ASVAB. Esta restricción puede hacer que tomar la prueba más difícil para algunas personas. En lugar de ser capaz de pasar por e inmediatamente responder a todas las preguntas que usted está seguro de y luego volver a las preguntas que le obliguen a hacer algo de rascarse la cabeza, tiene que responder a cada pregunta, ya que viene.
El Programa de Exploración de Carreras ASVAB CEP dura aproximadamente tres horas, abarca ocho asignaturas y consta de 200 preguntas. Actualmente, el ASVAB CEP es un examen que se hace con lápiz y papel. Si lo ofrece la escuela, los alumnos pueden hacer el examen ASVAB CEP en los grados 10, 11 y 12. Solo pueden realizarlo en la escuela a la que asisten, a menos que se hayan celebrado acuerdos especiales.

El ASVAB no tiene un puntaje general. Cuando escuchas a alguien decir: "Obtuve un 80 en mi ASVAB", esa persona está hablando de la puntuación de la Prueba de Calificación de las Fuerzas Armadas (AFQT), no de una puntuación general de ASVAB. El puntaje de AFQT determina si usted incluso califica para alistarse en el ejército, y solo cuatro de las subpruebas se utilizan para calcularlo:

Very helpful and has good tests. The actual ASVAB is easier, which is a good thing. Prepare and practice with harder tests and a study guide like this, and you will do well. Just give yourself plenty of time to study. Ideally at least a week at minimum. If I recall I practiced with this for 2 weeks. I scored 93 on AFQT. I was quite a few years removed from high school too, so I had to relearn some of this stuff. Others, I learned for the first time.

After adding so much information to the aptitude test, there was a bit of difficulty interpreting the test results. In addition to that, a vast majority of test takers were deemed as being under qualified based on their test results. This is why the percentile change was made. It ensured that a 50% actually correlated with a person doing better than 50% of the test takers. Those revisions have worked hand-in-hand with the preparation of the armed forces.
