• A grade-reference curve (GRC) can be constructed for any course based on the grades of a course in the last several years. Among other things, the reference curve of a course can be used to test for any abnormality in the current semester's grades of a course. It can be a very important document about the course that serves students, teachers and decision makers in the institution. A GRC of a course should be updated on a regular basis. In this article, the construction of such curve is outlined and illustrated by an example. The use of the constructed curve to detect abnormality via statistical analysis is also discussed and illustrated by an example.
