They are a means to produce feedback which the teacher and school can use to assess their quality of instruction. The process of (a) gathering information about the impact of learning and of teaching practice on student learning, (b) analyzing and interpreting this information, and (c) responding to and acting on the results, is valuable for several reasons. They enable instructors to review how others interpret their teaching methods. The information can be also used by administrators, along with other input, to make summative decisions (e. g. , decisions about promotion, tenure, salary increases, etc. ) and make formative recommendations (e. g. , identify areas where a faculty member needs to improve). Typically, these evaluations are combined with peer evaluations, supervisor evaluations, and results of student’s test scores to create an overall picture of teaching performance. Course evaluations are implemented in one of two ways, either summative or formative.
