This report of the third year of a Head Start study indicates the diverse range of information gathered on two types of programs (Philadelphia's inner city and Appalachian follow-up) in which the Child Development Research and Evaluation Center at Temple University participated. Subjects in the Philadelphia sample were 158 Negro children equally balanced between the sexes who had attended any one of twelve Head Start centers. In the Appalachian sample, the majority of the 41 subjects were Caucasian. They (1) had previously experienced at least a year of Head Start (2) had been tested in the 1967-1968 evaluation program, and (3) were currently in the first grade. Investigations of cognitive, social-emotional, and physical development which utilized both standardized and specially developed instruments were undertaken. Tabular presentations of test data are included. Faculty studies and research projects which relate to assessment of the continuing influence of Head Start are also included in this document. (WY)
