The use of the cohort-survival method for projecting student enrollments is widely known in educational finance literature; however, the limited information provided by the model impedes planners in making future operational decisions. The cohort-survival method employs historical rates of usage to predict future patterns of usage and produces a grade-by-grade forecast for each student cohort. This paper presents a model that develops multipliers for several student-support programs to create a broad base of information. The model accommodates the number of regular public school students by grade level as well as an estimate of certain student-support programs--compensatory education, bilingual education, and 11 categories of special education. The model incorporates student-support-program requirements and adds the numbers of retained members to the next cohort, thus presenting a more accurate view of the enrollment picture. Two figures are included. (Contains nine references.) (LMI)
