- ABSTRACT A Computerized Adaptive Test (CAT) is a test administered by means of a computer where the items are given to the examinee progressively depending on the performance achieved with the previous ones. This procedure allows for more precise measurements in less time. Despite these advantages, the conditions for the application of the CATs are very little flexible in comparison with conventional tests. CATs do not permit omitting or deferring item responses nor reviewing them. This generates a significant increase of anxiety in the examinees that may affect the estimated performance. These conditions make the evaluation been perceived as frustrating and unfair from the point of view of examinees, which endangers the apparent validity of the test. The adaptive administration leads to reduced subjective sense of success because, regardless of individual’s ability, everyone has a similar proportion of correct answers (approximately 50%). Current attempts to improve the conditions of the applications of CATs are mainly focused on preserve examinees’ motivation and prevent a level of anxiety that may hamper the task. There is no point in looking for greater reliability when the estimated skill level is being distorted by the subjective experiences of the examinee.
RESUMEN
Un Test Adaptativo Informatizado (TAI) es una prueba administrada
mediante una computadora donde los reactivos que se le presentan progresivamente al individuo dependen del rendimiento alcanzado con ítems previos. Este procedimiento permite obtener una
medida más precisa en menos tiempo. A pesar de estas ventajas,
las condiciones de aplicación de los TAIs son muy poco flexibles en
comparación con la que presentan los test convencionales. Los
TAIs no permiten omitir o diferir la respuesta a los ítems ni tampoco
revisarlos. Esto genera un incremento significativo de ansiedad en
los evaluados que pueden perjudicar el rendimiento estimado. Desde la visión de los examinados estas condiciones tornan a la evaluación frustrante e injusta, lo que amenaza a la validez aparente
del test. La administración adaptativa produce una menor sensación subjetiva de éxito dado que, independientemente de la capacidad del individuo, todos tienen una similar proporción de aciertos
(aproximadamente del 50%). Los intentos actuales por mejorar las
condiciones de aplicación se centran principalmente en cuidar la
motivación de quien responde y evitar un nivel de ansiedad que
obstaculice la tarea. De nada sirve buscar una mayor confiabilidad
cuando el nivel de habilidad estimado está siendo distorsionado
por las experiencias subjetivas del evaluado.
