A study to gather information describing model infant and preschool programs for handicapped children in California is reported. Information was received from 142 proqrams (102 in California) including validated First Chance projects, Outreach projects funded by the Bureau of Education for the Handicapped, Master Plan agencies in California, innovative and preschool incentive grant programs in California, exemplary Head Start programs, and other model programs in the public and private sectors. A compendium of program descriptions was developed to help state and local educators in selecting the most appropriate early intervention model for adoption/adaptation, consistent with federal and state law, specific to local needs, and available resources. The survey included questions on the following: general information (such as the average number of years in operation), instruction and assessment, service delivery, use of staff, program placement, parental participation, dissemination, training and technical assistance. Among many findings were that the programs are heavily concentrated in urban and suburban areas, that the most popular instructional model in use is developmental, that wide use is made of community resources, and that two thirds of the programs report providing mainstreaming to some degree. Data from the survey are reported in an accompanying summary document which charts program characteristics against answers from public and private agencies or schools. (DB)
