The purpose of this descriptive summary was to report on a Swedish preschool curriculum evaluation project. The study had as its purpose to evaluate the existing preschool program by comparing 130 preschool children with 130 home-based children on a number of variables relating to preschool objectives. This evaluation was carried out when the children were in first grade, with a follow-up study done two years later. The home group (the control group) was chosen from among the children on the waiting list for preschool. Matching was performed on the basis of sex, age, father's occupation, living area, and number of siblings. Although results did not clearly indicate whether preschool was a favorable experience for all children, certain specific positive gains were evident. An experimental preschool program was designed based on the findings and implications of this evaluation study. (CS)
