Abstract
The purpose of this retrospective study was to investigate the influence of several factors on students' course evaluation scores. Scores from the past five years were collected from all the professors in the Pharmaceutical Sciences Department, and then examined with respect to differences between graduating classes, the percentage of A and B grades given, average grade given, and difference between professors co-teaching in the same course. The results of this study indicate that students' evaluation scores are not influenced significantly by any one of these factors, but rather are influenced primarily by the students' perception about the professor.
