Por ejemplo, si recibe una puntuación percentil de 72, se puede decir que su puntaje es tan bien o mejor que 72 de 100 del grupo de la norma que tomaron el examen. (Y, por cierto, esta estadística a partir de 1997 no es un error tipográfico. El ASVAB última " re-normado " en 2004, y el grupo de la muestra utilizada para la norma era esa gente que tomaron el examen en 1997.)
Comer una comida ligera antes de la prueba (el desayuno o el almuerzo, dependiendo de la hora de prueba). Usted estará en mejores condiciones para pensar cuando se tiene algo de comida en el estómago. Sin embargo, no comer demasiado. Usted no quiere estar somnoliento durante la prueba. Además, no beber demasiada agua. Los procuradores de prueba le permitirá usar el baño si es necesario, pero con ciertas reglas.
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.
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.
Understanding the ASVAB score range is to understand standard deviations. The highest score on the ASVAB is a 99 and the lowest score is a one. Scores are based on the mean of all examinees. This is to say that a score of 50 would account for an average score. Each increment of 10 represents a single standard deviation from the mean score. So, for example, a score of 80 would be three standard deviations better than the meanwhile a score of 30 would be two standard deviations lower than the mean score.
The various armed forces adopted all of those aspects in 1976. At that point in time, the test was in its written form rather than today’s more common form (computerized test format). The written form covers all of the previously mentioned areas as well, which is why both forms are still available. All-in-all that answers the question concerning the intention of the test.
