A computerized curriculum monitoring system (CMS) was developed at Shelby State Community College (SSCC) in Tennessee to restrict student registration to courses for which they have completed the prerequisites and corequisites. The CMS is a subroutine of the on-line registration program, which matches students' course selections against their academic records to ensure that students are eligible for enrollment. To complete its routine, the computer program must interact with the following files: (1) the schedule of courses, a list of courses offered during a given term; (2) an academic record-keeping system, which contains information on students' personal characteristics, degree objectives, test scores, and courses completed; (3) the course title file, a table of all courses offered at SSCC, indexed by discipline and prerequisites/corequisites; (4) the inventory of degree plans tables, which lists course requirements for degrees offered at SSCC; and (5) the interactive registration system, which performs the prerequisites/corequisites check. When the system was first implemented in fall 1987, data collected during registration indicated that 21% of the students had not fulfilled the prerequisites or corequisites for the courses in which they were attempting to register, even though their registration forms indicated that they had undergone academic advising.
