The adaptive test is exactly what it sounds like, a test that adapts to the test taker. Questions in each section range in difficulty, and based on the test taker’s answers, the question types and difficulties adjust with each answer. This type of test allows for a greater level of accuracy in evaluating a prospect’s abilities. For the most part, correct answers beget more difficult questions while wrong answers will reduce the difficulty of proceeding questions.
la prueba de Aptitud Vocacional de las Fuerzas Armadas, por lo general abreviado a simplemente ASVAB es una prueba propuesta por el ejército de Estados Unidos para ayudar a evaluar los niveles de habilidades y conocimientos básicos de los candidatos. En general, resultados de las pruebas determinan la aceptación en las fuerzas armadas y en qué área te pueden sobresalir. Los resultados se dan como ASVAB puntuaciones estándar, lo que significa que los números reportados están relacionados con la forma en la población en las puntuaciones generales en la misma prueba. Las puntuaciones de 50 o más significa que su puntuación es buena o mejor que la media nacional. Los puntajes inferiores a 50 indican que se marca menos de la media.
You can't use the AR and MK score shown on your ASVAB Score Sheet. The Score Sheet shows "number correct" for your AR and MK Scores, because "number correct" is what is used for job qualifications. However, the military does not use this same score when computing the AFQT. They use the "weighted scores" of the ASVAB sub-tests for AR and MK. Harder questions in these areas get more points than easier questions. The "weighted scores" for AR and WK are not listed on the ASVAB score sheet given to you after the test.
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.
