In the IDEA Student Ratings of Instruction (SRI) system, students complete self-ratings of their "work habits," "motivation," and "background preparation." Average course ratings on these characteristics are important variables used in adjusting scores on student ratings of progress on relevant objectives (PRO), excellence of the instructor, and excellence of the course (Benton, Li, Brown, Guo, & Sullivan, 2015). The purpose of this study was to examine whether student self-ratings are related to the instructor's corresponding ratings of the class as a whole. The current findings provide evidence of the concurrent validity of student self-ratings on work habits, motivation, and background preparation. Significant and meaningful relationships exist between average student self-perceptions on these characteristics and the instructor's overall impressions of the students enrolled in the course.
