Abstract
A computer program (DICOT) for the Rasch analysis of classroom tests is described. Results are presented in a simple, self-explanatory form, and person ability and item difficulty estimates are expressed in a metric like the one with which teachers and parents are already familiar. Person and item fit statistics provide an opportunity to diagnose strengths and weaknesses of individual children and to identify items which are problematic.
