This study was designed to assess the extent to which children served by the Model Schools Division Preschool Program developed socially, intellectually, physically and emotionally during the 1973-74 school year. This evaluation was also designed to measure the appropriateness of the learning environment and the amount of services provided by the program. Program objectives are given in terms of four basic components: Education, Social Services, Parent Involvement and Health Services. The evaluation design contained five types of instruments: preschool behavior, attitude and achievement inventories, staff and parent questionnaires, and an observation checklist for use in the classroom. Data for the evaluation were collected for approximately 300 students. Findings are presented in discussion and table form. Recommendations for program improvement are included. The appendices contain an evaluation instruction sheet, the instruments used in the evaluation measurement, additional supportive tables and data information, and administrator reports. (SDH)
