Informal inquiries were directed to nine community colleges that have had to plan a new campus in order to determine the variables affecting the impact of the new campus on the existing one. Information obtained is to be applied to the analysis of the impact of the proposed Clinton campus of Prince George's Community College (Maryland) on the existing campus at Largo. Of particular interest is the way enrollments at Clinton can be expected to affect enrollment patterns at Largo. The influential variables emerging from the inquiries were: (1) proximity to a reference population, (2) accessibility of each campus, (3) the plan for scheduling programs and (more importantly) courses, and (4) the specialization intended to apply to each campus. Enrollment patterns at a multicampus school apparently are not entirely dependent on the vagaries of the student but depend in part on the educational program at the new campus. Certain institutions surveyed also indicated that an initial dip in enrollments at the existing campus possibly may occur. (KM)
