As any professional military commander will tell you, knowing your enemy is the first step in winning a battle. After all, how can you expect to pass the ASVAB (Armed Services Vocational Aptitude Battery) if you don’t know what’s on the test? Here are some test-taking tips and key info about ASVAB test formats to help you ace the test, get into the service of your choice, and qualify for your dream job.
Por ejemplo, si recibe un puntaje percentil de 72, puede decir que obtuvo una calificación igual o mejor que 72 de cada 100 del grupo de normas que tomó el examen. (Y por cierto, esta estadística de 1997 no es un error tipográfico. El ASVAB fue "re-normado" por última vez en 2004, y el grupo de muestra utilizado para la norma fue la gente que tomó el examen en 1997).
Los miembros de la Reserva de la Fuerza Aérea son responsables del 20% de los trabajos realizados por la Fuerza Aérea. Un número creciente de ellos están trabajando en puestos de reservistas a tiempo completo, en ingeniería civil, mantenimiento aeroespacial, apoyo a las misiones y operaciones de la tripulación aérea. Para calificar para el alistamiento en las Fuerzas Aéreas, necesitas un puntaje AFQT de 36 si tienes un diploma de escuela secundaria, y una puntuación AFQT 65 si tienes un GED.

The test is part of the larger ASVAB Career Exploration Program. The Program uses the test to help students identify both their interests as well as their strengths in three skills areas (verbal, math, and science and technical skills). Based on a student's skill levels, information is provided about more than 400 occupations in order to enable students and parents to judge their potential success in areas that interest them the most. Schools that may be facing budget cuts or finding themselves with limited resources devoted to career counseling are encouraged to find out whether using the ASVAB Program would be useful, as the testing and career development services are free of charge.

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.
