La Salle University México (La Salle) uses an internal system of professors' evaluation, which main purpose is to evaluate professors' performance and secure high quality of teaching at all of its faculties. Since its inception in 2010, La Salle has obtained 517,635 individual evaluations of 45,346 courses. However, no additional analysis of the obtained results has ever been done. This article provides introductory analysis of the accumulated results at faculty level. The main objective is to analyze whether there are differences between faculties regarding the evaluation. Although the results are highly skewed towards the maximal evaluation at all faculties, there are statistically significant differences. The next important task is to investigate what factors influence the evaluation. Moreover, as this is the introductory analysis, the article concludes with possible future steps that should be consider regarding eventual structural changes in the evaluation system.
