A revalidation of the SET37 questionnaire for student evaluations of teaching

In this study, the authors report on the validity and reliability of a paper-and-pencil instrument called SET37 used for Student Evaluation of Teaching (SET) in higher education. Using confirmatory factor analysis on 2525 questionnaires, a revalidation of the SET37 shows construct and discriminant validity of the 12 dimensions included in the instrument. The retest of the instrument reveals (again) the existence of a second-order factor explaining a substantial amount of the variance in seven dimensions of the instrument. In sum, the results provide strong support for both the relevance of the questionnaire and the hypothesis that the SET37 has a multidimensional structure but is compatible with a general underlying factor called "Teacher professionalism".
