Evaluation of a Title I Prekindergarten Program serving thirteen elementary schools is presented. Through a screening test, children most needing prekindergarten experience were chosen for participation. The program followed the Piagetian theory of child development concentrating on the cognitive, psychomotor, and affective domains. Both process and product evaluations were conducted. The former concentrated on determining whether classroom activities matched those stated in the proposal, the roles of parents/aides in the classroom, and what efforts were made to remedy screening problems observed in the previous year. The product evaluation employed the Prekindergarten S.O.R.T. instrument to measure thirteen of the program's sixteen objectives. The Prekindergarten Program proved to be successful; in addition, the following recommendations are offered: (1) attention should be paid to the building level achievement data; (2) the Department of Evaluation, Testing and Research should monitor the screening process; (3) recruitment publicity should be increased; (4) a plan for a bilingual prekindergarten experience should be formulated; (5) the Title I Prekindergarten Supervisor Monitoring Instrument should continue to be used; and (6) the inservice program should be expanded.
