This fourth year report summarizes the services rendered during 1969-1970 by the New York State Experimental Prekindergarten Program and includes a partial evaluation of the accomplishments of the program as compared to its stated goals. The report is based on questionnaire responses by 49 of the 50 programs, including New York City. Because of its complexity, the New York City data is presented in a separate section. Seven demonstration centers for inservice education are included in the 50 programs. Answers to the survey questionnaire provide anecdotal records, statistical data, and subjective descriptions of techniques used to achieve goals. Topics covered are: recruitment and selection of children; planning and programing in the classroom; parent involvement; evidence of growth and development; and planning for continuing goals in kindergarten and primary programs.
