The report contains an overall account of three annual evaluation studies (1971-73) of a project designed to demonstrate how four components supplemented the existing counseling system in the Pittsburgh Public Schools. The components providing occupational information were: (1) a career orientation program for sixth, seventh, and eighth grades; (2) a cooperative work experience program for secondary students enrolled in marketable skill-centered programs; (3) a placement program for high school graduates; and (4) Project SET (Select Employment Trainee), a counseling/training program for alienated potential high school drop-outs not enrolled in vocational programs. A summary describes each of the components and presents major conclusions of the three year evaluation reflecting the general success of the program. Other sections of the report provide descriptions of the interactive process used in evaluation, detailed descriptions of the program components, and the procedures used for each of the three evaluations. An in-depth discussion of the evaluation results (including tabulated achievement test scores and attitude data) is presented cumulatively by year for each project component, with emphasis on the third year. Appended are student, parent, and employer questionnaires for the project components, and a student achievement test for the career orientation program. (Author/MS)
