A tested approach to college enrollment management is presented that offers a system to assess and develop options for researching, maintaining, or improving enrollment goals. The new approach, the Enrollment Management Matrix, consists of three dimensions: (1) key variables in enrollment management (institutional product, data and information, and the effects of institutional climate); (2) critical attributes to address in relation to each variable (goals, resources, content, and process); and (3) attitudes and beliefs about the key variables and attributes. Each aspect of an institution, and ways that they interact, are analyzed in detail. The matrix allows administrators to manipulate the key variables individually or simultaneously to structure the best steps to effective action and to formulate positive, long-term solutions to enrollment problems. The text includes an extensive bibliography, a glossary of enrollment terms, and a description of the database use. Checklists, forms, cases, models, tables, charts, and graphs illustrate the book throughout. Data from 1,239 student surveys (18.8% response rate), taken largely from the 1986 National Student Database developed by The Ingersoll Group, are described in the appendix. The survey form is included. (LB)
