dc.description	El presente trabajo se realizó con el propósito de mostrar que el grupo es un modificador de la relación entre el rendimiento académico y sus predictores y con ello, fundamentar la necesidad de recurrir a la modelación jerárquica para la predicción del rendimiento. Se aplicaron modelos con coeficientes aleatorios, especialmente apropiados para la circunstancia frecuente de casos agrupados, en la que los supuestos usuales de los modelos lineales ordinarios dejan de ser válidos y los modelos clásicos, inaplicables. Se constató que algunos de los predictores tradicionales tenían relevancia condicionada al grupo, aunque no parecían tener relevancia marginal. Se demostrró así que el grupo es un modulador de la relación entre el rendimiento académico y algunos de sus predictores. La consecuencia de mayor trascedencia fue que la asignación de un estudiante a un grupo podía influir considerablemente en su rendimiento académico, independientemente de sus condiciones iniciales.<br>The present paper was aimed at demonstrating that the group acts as a modifier of the relation between the academic performance and its predictors, and at founding the need of resorting to hierarchical modelling to predict this performance. Models with randomized coefficients, specially appropriate for the frequent circumstance of grouped cases, where the suppossed ordinary lineal models are not valid anymore and the classical models are unapplicable, were applied. It was proved that some of the traditonal predictors were relevant according to the group, though they did not seem to have marginal relevancy. This way, it was demonstrated that the group was a modullator of the relation between academic performance and some of its predictors. The most significant consequence was that the assignation of a student to a group may influence considerably on his academic performance, independently of its initial conditions.
