This report presents an evaluation of a Title I preschool program which served 403 children during the 1973-74 school year, and was designed to prepare disadvantaged 4-year-olds for entry into kindergarten. In terms of instructional approach, the program closely followed Piagetian theory and included preservice and inservice teacher training. The program was evaluated in terms of 26 product and 26 process objectives, covering the affective, cognitive and psychomotor domains. The procedures for process evaluation employed the locally developed Classroom Activity Checklist as the primary instrument. Four locally constructed instruments were used in the product evaluation. In addition, parent participation records were kept by the classroom teachers. Process data indicated that the program was implemented as planned, and product data showed that the pupils mastered 25 of the 26 product objectives. Data tables and appendices make up approximately one-half the document. (SDH)
