The scores from the Word Knowledge, Arithmetic Reasoning, Mathematics Knowledge, and Paragraph Comprehension are combined together and known as the Armed Forces Qualification Test (AFQT). Your AFQT scores represent a percentile between 1 and 99 and measure your ranking compared to scores from other 18 to 23 year olds. If you score a 70 on your AFQT, this implies that you scored better than 70% of test takers. Your scores on the other six ASVAB tests will help identify which jobs may be appropriate for you in the military.
The vast majority of ASVAB test takers will ultimately not enlist in the military. The ASVAB Career Exploration Program claims that only two-and-a-half percent of those who participate in the ASVAB join the military. Forty-seven percent of those who take the exam indicate an interest in attending a four-year college, and 16 percent of those who take the exam originally indicate some kind of an interest in joining the military.
All test takers are given a summary results sheet that shows their percentile score in every test area. A percentile score of 50 means that a score was achieved that was better than 50 percent of all test takers. Percentile scores are given specifically for test takers of their gender and their grade level. Information obtained from the test is only shared with agencies within the Department of Defense. Test takers are informed that their specific scores will be used for up to two years for recruiting purposes. After two years, test scores will be used for research purposes only.
The paper-and-pencil version of the test administered at a Mobile Examination Test (MET) site usually takes 3–4 hours. The time needed to take the CAT-ASVAB test can vary. The test is adaptive. If the candidates answer a question correctly, they are given one of increasing difficulty. If the candidates miss a question, they are subsequently given an easier item. This pattern continues until the test is finished. Because of its adaptive nature, the CAT-ASVAB test generally takes about half the time of the paper-and-pencil version.

Durante el proceso de alistamiento inicial, su rama de servicio determina su trabajo militar o programa de reclutamiento basado en las puntuaciones de línea mínimos establecidos. Si obtiene una puntuación adecuada en las áreas apropiadas, usted puede conseguir el trabajo que desea - siempre y cuando ese trabajo está disponible y cumple con otros factores de clasificación.
Military Working Dog (MWD) handlers are responsible for the care and training of his or her service dog, which contributes to combat operations abroad and installation security at home by providing target odor detection (explosive/drug). Service dogs, generally seen as a non-lethal option for neutralizing a threat, also serve as a psychological deterrent during law enforcement operations.  
La Información de automóviles y talleres evalúa la aptitud para el mantenimiento y la reparación de automóviles, y las prácticas de los talleres de carpintería y metales. El examen abarca varias áreas que se suelen incluir en la mayoría de los cursos de automóviles y talleres de las escuelas secundarias, como componentes automotrices, sistemas automotrices, herramientas automotrices, solución de problemas y reparación, herramientas de taller, materiales de construcción y procedimientos de construcción.
Las Ciencias generales evalúan la capacidad de responder preguntas sobre una variedad de temas científicos que se enseñan en la mayoría de las escuelas secundarias. Los temas de biología abarcan botánica, zoología, anatomía y fisiología y ecología. Los temas de las ciencias de la tierra y el espacio están basados en astronomía, geología, meteorología y oceanografía. Los temas de las ciencias físicas miden la fuerza y la mecánica del movimiento, la energía, los líquidos, la estructura atómica y la química.
The scores from the other tests are used to determine what type of specialty you might be best suited for.  These "composite" scores (also known as line scores, MOS scores, or aptitude area scores) are calculated by adding together combinations of the different sub test standard scores. These composite scores are then used to determine which different military jobs (aka Military Occupational Specialties or MOS) may be the best fit for you.  Each branch of the military will have their own approach to these composite scores.
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.
