This work presents quantitative and qualitative results about three physics questions of a Diagnostic Tool at Arrival that is applied to junior students at School of Engineering of Universidad de la Republica. The analysis is based on the Item Response Theory. The same questions were given with small changes to three consecutive generations, aiming to characterize the students that have shown no cognitive and attitudinal competences required by the institution and, in turn, proposing educational actions in order to improve their learnings.
