The program development guide describes the Fairfax County (Virginia) Noncategorical Early Childhood Program (NECP) which serves approximately 75 mildly and moderately handicapped children from 2 to 8 years of age with either a preschool home resource program, a class based preschool program, or a class based primary program. The guide is designed to provide information about the NECP model and its use of the noncategorical concept, mainstreaming, educational teaming, and a parent program. Separate sections describe the child services and curriculum, the mainstreaming progression, the feeder curriculum (which serves as a transition from special to general education), teaming, the parent program, and evaluation methods and results. Among evaluation results were that preschool and primary students showed greater than expected progress in all skill areas, that parents' perceptions of their children's progress was highly positive, and that parents felt that the NECP program provided much needed emotional support as well as increased knowledge and skills. Detailed evaluation tables are included. Sources of additional program information are listed. (DB)
