Reliability and Validity Evidence for Scales Measuring Dimensions of Student Ratings of Instruction

In three studies, students in introductory psychology classes evaluated their instructor on a set of student-rating-of-instruction items. Based upon item content and the results of a component analysis of the item intercorrelations in each of the three samples, four scales were constructed. High internal consistency estimates of reliability and similarities in the scale intercorrelations were present over the three studies. The scale scores were judged to possess an acceptable degree of internal consistency and construct validity to be of use in further research investigating correlates of student ratings of instruction.
