In the paper we present a comprehensive methodology for the analysis of student ratings of university courses. First, simple descriptive measures, which take into account the ordinaI nature of the ratings, are discussed. Then net measures, which adjust for the characteristics of the students, are obtained through multilevel modelling. Finally, the measures relative to the various aspects of the course are synthesized through a weighted mean, building gross or net multidimensional indicators of course quality. The different indicators are then contrasted with respect to the rankings of courses they induce.

Abstract
In the paper we present a comprehensive methodology for the analysis of student ratings of university courses. First, simple descriptive measures, which take into account the ordinaI nature of the ratings, are discussed. Then net measures, which adjust for the characteristics of the students, are obtained through multilevel modelling. Finally, the measures relative to the various aspects of the course are synthesized through a weighted mean, building gross or net multidimensional indicators of course quality. The different indicators are then contrasted with respect to the rankings of courses they induce.
