In May 1993, the California Community Colleges' Board of Governors adopted systemwide guidelines recommending student registration priorities to help address current discrepancies between available resources and courses and the colleges' open-door mission. This report describes the guidelines and results of a study conducted to determine their implementation at the colleges, as well as other enrollment management (EM) initiatives in use. First, background on the guidelines indicates that due to funding reductions, the colleges have cut course sections by 10% since 1990 and have experienced a 9% decrease in headcount enrollment since 1990. Next, findings from the study of college practices are presented, including the following: (1) only 4 of the 107 community colleges in the state did not have formal registration priorities, while for the 103 with priorities, the most common criteria were continuing students, disabled/equal opportunity students, units completed, and matriculated students; (2) 28 of the colleges with priorities follow the Board's guidelines by designated students with baccalaureate degrees as the lowest priority, and (3) with respect to changes from 1992-93, matriculated and returning students, units completed, and grade point average increased most in use. Finally, information is provided on other EM practices in use, including adjustments to curricula, marketing, admissions/registration processes, retention strategies, pricing, and delivery methods. Appendixes provide the Board guidelines, the survey instrument, detailed survey results from 1992-93 and 1993-94 studies, and data on EM activities at the colleges. (KP)
