Funding for proposed community college facilities in California is based on a method which applies recognized space and utilization standards to expected future instructional activity as expressed by weekly student contact hours (WSCH), the product of student enrollment estimates, and expected future instructional loads. Until 1974, official projections of enrollment and WSCH were based on applying participation rates and grade progression ratios to counts of recent high school graduates. However, changing enrollment patterns and increasing participation by students of all ages have made accurate projection by this method increasingly difficult. To solve this problem, the old projection techniques have been replaced with a new age participation model which uses the entire population rather than just high school graduates as a projection base. Projected WSCH on which the 1974 bond program was based contains 17 district projections under the new technique and the remainder under the old technique. The 1975 projection will be based on the new technique. This document describes in detail both the bond program projection technique and the new age participation technique, briefly describes six alternative methods of enrollment projection, and gives graphs and tables of the results of such enrollment projections.
