A "prerequisite" is a measure of readiness for a course or program that a student is required to meet as a condition of enrolling in a course or program. An "advisory" is a measure of readiness for a course or program that a student is recommended to meet in order to enroll. A prerequisite or advisory may be a course, activity, audition, test, or similar measure of readiness.
