This document presents a descriptive typology created to characterize the diverse program approaches of the Follow Through Planned Variation Experiment. Program approaches are described with respect to two orthogonal dimensions: (1) Program Elements (Instructional, Service, Participatory and Employment) with the major focus on instructional elements including curricular orientation (learning emphasis and instructional role); curricular design (nature and uniformity of activities, time utilization, instructional grouping); curricular responsibility (pre- and post-instructional); and curricular variability (instructional activities, time utilization, and instructional grouping); and (2) Target Population (Children, Instructors and Parents). To demonstrate the use of this typology, five Follow Through Planned Variation program approaches are described using the previously developed program descriptors. (Author/MS)
