The purpose of the study reported here was to design a model for the development of a human relations program in selected racially mixed public schools. The following efforts were undertaken: (1) an examination of the literature to obtain the rationale for school desegregation, (2) an identification of a national sample of desegregated school districts and a survey of their human relations programs, (3) an identification and further analysis of the efforts of the most successful and the least successful school districts in the national survey and the reasons and conditions for their success or failure, (4) a survey of the existing conditions and constraints which affect human relations programs in selected racially mixed schools of the pilot school district, (5) an analysis of the data in steps 1-5 in order to develop a model for the human relations program. Two sampling procedures were required. The first drew a national sample of school districts which provided information on what desegregated schools were doing to help their staff adjust to the climate of the racially mixed school. The second identified those schools in the pilot school district, that of Philadelphia, whose programs could be improved by the development of a human relations model. (Author/JM)
