A practicum designed to facilitate the transition of Head Start children to kindergarten was implemented by the education coordinator of a Head Start program. The program served 945 poverty-level children in 35 classrooms and 20 home-based sites in 35 school districts in Allegheny County, Pennsylvania. Practicum goals were to prepare children for transition to public school, train parents to aid in transition, and promote cooperation between Head Start and public school districts. Objectives were as follows: (1) training selected Head Start staff to identify transition needs of graduates and work with parents to address children's needs; (2) fostering mutual understanding of Head Start and public school elementary programing through an information sharing and site visitation system; and (3) training up to 100 parents in strategies they could use in transition activities with their children at home during the summer. As a result of the practicum: (1) an interagency task force developed a checklist of kindergarten prerequisite skills; (2) cooperation between the two agencies increased; (3) parents acquired skills they needed to work with the children; (4) cross-site visitation increased awareness between sending and receiving teachers; and (5) parent participation increased. Related materials making up one-third of the document, are appended, including assessment forms and the kindergarten prerequisite skills checklist. (RH)
