The major objective of the project was to: assess the long-term impact of continuous educational stimulation on achievement of children entering the early education program at age 3 and continuing until age 9. A secondary objective was to: assess the long-term impact of continuous educational stimulation on behavior of children entering the program at age 3 and continuing until age 9. Comparisons of standardized test scores of children with 0,1,2, or 3 years of pre-primary experiences scored significantly higher on MRT, CTBS, and SAT than children without pre-primary experience. Initial differences between Control and Experimental groups were not overcome by end of grade 3. The Experimental children were characterized by: lack of fear of new situations, personnel, experiences, and materials; being "doers"- no non-participators; absence of learning disabilities or emotional problems traceable to the programs, and enjoyment of school attendance. Complaints were registered when school was closed for holidays. (Author)
