Enrollment simulation and planning (ESP) is centered on the use of statistical models to describe how and why college enrollments fluctuate. College planners may use this approach with confidence to simulate any number of plausible future scenarios. Planners can then set a variety of possible college actions against these scenarios, and examine the results of projected future enrollments for their planning implications. This book begins with an introduction that explains three lines of inquiry--environmental scanning, enrollment determination, and enrollment management--that provide conceptual background for ESP and help to highlight the differences between manageable and unmanageable factors. Examples from case studies are presented throughout the book to illustrate the ESP model. Part 1, "Studying Enrollment," begins with ways to identify a community college's key enrollment trends, students' enrollment behavior, how factors within and outside the college's control affect enrollment, and what is and should be the college's market penetration. Part 2, "Forecasting, Simulating, and Planning," discusses how ESP can be useful in predicting how changes will have their intended effects, given that some important determinants of enrollments are outside the college's control. (This book contains 25 figures, 5 tables, 3 appendices, an index, and 30 references.) (VWC)
