Abstract: Online exercise systems should be able to automatically adapt the level of difficulty of the problems to the level of proficiency of the learner. In our Communication and Tutoring Sys-tem CATS we have implemented a measurement algorithm that keeps track of the perform-ance level of a learner by measuring the percentage of correct answers at the current level, the reliability with which the learner answers the questions and the time he/she takes. From these measures we derive a unified performance parameter that controls the presentation of the next set of questions. These are then generated dynamically by the exercise applet.
