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.
Candidates taking the ASVAB are given a AFQT (Armed Forces Qualifying Test) score which is simply a combination of your scores from four tests (Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge, and Paragraph Comprehension). This AFQT score is represented as a percentile (from 1-99) which depicts how well you scored compared to other test takers. For example, if your score is a 57, this means that you scored better than 57% of the other test takers. The AFQT score is used to determine whether you are qualified to enlist in the U.S. Armed Forces.
Don’t be fooled by the appearance of the low numbers, the algorithm that computes the AFQT is very sophisticated. Just because your ASVAB score is 40 doesn’t mean that you only got 40% of the questions correct, it could simply mean that you lack strength in one area, but succeed with high praise in another. Your ASVAB score is only a means by which you are categorized for available positions; it is by no means a measure of intelligence.
Centrarse en las subpruebas que le importan. Si usted tiene un claro interés en seguir una carrera en la electrónica, la subprueba de Información Electrónica debe estar en la parte superior de su lista de ACE. Aunque usted querrá asegurarse de que todos sus puntuaciones de línea son buenos (en caso de que una nueva formación o su trabajo deseado no está disponible), se centra en su experiencia en ciertas áreas de interés que un candidato hace más deseable.
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.
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.
