This article is a practical application of the technique of factor analysis. Its uniqueness lies in the nature of the variables we set out to study (determinants of the quality of university teaching), the data collection instrument designed for the study (scale assessment questionnaire) and the basic goal of this study, which is simply to seek the views of a representative sample of university students on the elements that form a system of indicators for assessing teaching skills in order to establish a profile of the role of university professor.
