An evaluation was conducted to determine the effects of the General Electric Foundation Summer Institutes on Career Education and Guidance over a one to two year period in participating school districts and communities. The study evaluated the team-oriented institutes held in 1976 and 1977 at the University of South Carolina and Indiana University. The report describes the procedure used for designing the evaluation study, identifying the potential data, selecting the sample of school districts to be included in the study, and collecting and analyzing the data. Results show that the institutes had high impact on career education activity in two districts, moderate impact in one, and low impact in three. Substantial gains in personal and professional development were reported by most participants. Conclusions, policy implications, and recommendations were formulated for professional and personal development and team and team plan aspects of the institutes. It was recommended that the institutes be continued with modifications in the schedule and activities of the institutes and in pre-institute and post-institute operations.
