A notebook for participants in seminars on enrollment planning is presented. The seminars were sponsored by the National Center for Higher Education Management Systems. Seminar objectives for session 1 included: to understand the strategic enrollment issues, to review the national and regional demographic trends, and to understand that individual colleges are facing different enrollment situations (decline, stability, and increase). For the participant's college, objectives were to review actual enrollment trends and to determine possible implications of enrollment changes and alternative courses of action. Statistical charts and graphs are included. Session 2 identified key enrollment factors to be watched, including birth rates and high school graduates, regional shifts, student individual characteristics, and enrollment characteristics and shifts, such as trends by class/year, level, field of study, and part- and full-time status. Institutional-specific enrollment factors were also identified, including economic conditions, government policies, population migration, and tuition levels. Session 3 provided a case study for Aguinas College (Michigan) that includes a statement of problems and actions taken. Included are a list of seminar participants and a list of seminar topics and schedules for 1982. (SW)
