In the virtual platform for Statics course of the Engineering School at EAFIT University a Computer Based Test (CBT) and a Computerized Adaptive Test (CAT) were applied to measure the student's ability in previous subjects required for the Statics course. It was proved that the CAT's tests determine the student's ability with less amount of questions and take the examinee to the threshold of his capacity trough increasing levels of difficulty in contradiction to CBT's tests in which a fixed set of items is used. But in CAT's the duration time for the execution is higher. This paper presents the analysis of the collected data in both tests and it exposes the conclusions on the CAT's tests for the education in engineering.
