Prior to the survey due date, students can go back and edit their own responses. We do not interpret the students' responses on the survey, and we cannot examine student responses while the survey is still running. Any instructor who feels that a student has incorrectly submitted comments for another instructor or reversed the answer scale should communicate this to his or her department chair. The department chair should request in writing that the survey responses be reviewed and reprocessed. In many cases, students report that they they have made a mistake, but they merely misremember the details of filling out the survey. Requests for corrections should only be made after reviewing the survey results and ascertaining that a mistake does in fact exist and impacts the outcome. All requests for the department must be submitted together because each correction may affect the entire department mean.
