Although enrollment is one of the bases by which the state funds its segments of higher education, different assumptions and calculation methodologies exist between the California State University and Colleges and the University of California in determining the enrollment statistics reported for budgetary purposes. The state legislature therefore demanded development of standards and reporting criteria. This report provides a common terminology as an assistance to those people concerned with developing more reliable means of comparing segmental enrollments. The principal differences between UC and the state university and colleges are in determining full-time equivalent (FTE) students, and in designating students as lower division or upper division undergraduates. The glossary of enrollment terms designed by the staff of the Postsecondary Education Commission is discussed and recommendations for improving the budget proposal process are offered. (LBH)
