This digest discusses issues related to the implementation of high quality early childhood education by public school districts. Contents focus on: (1) the development of a written statement of philosophy; (2) the analysis of screening and assessment practices; (3) organization of the learning environment; (4) teacher preparation; (5) parent involvement; (6) collaboration with the community; and (7) ways to sustain programs. It is concluded that public schools can change to better meet the needs of young children. Such changes should be carefully planned and based on research and theory about what is appropriate for young children. Changes should be supported by commitment from the district's decision makers and by an increase in the time allotted for planning, training, and problem solving. Each change can be implemented over a period of time so that those involved have time to make preparations. (RH)
