ESCI makes the process of gathering and summarizing student course feedback easy for instructors and departments, while providing flexibility to create customized surveys. Instructors can use ESCI survey reports to reflect on and inform their teaching. Additionally, Red Binder section 1-31 requires that summary information for the two campus-wide ESCI questions, “Item A” (overall evaluation of teaching) and “Item B” (overall evaluation of the course) be included in personnel cases, along with one other source of teaching evidence.
Note that while the term "evaluation" was originally included in the name of the service at its creation in the 1970s, the ESCI system itself does not make evaluative judgments - it simply reports the students’ responses. An extensive body of research has documented systematic bias in student evaluations of teaching against females and people of color (link). To minimize this potential harm, ESCI data should be used in conjunction with other sources of feedback.
