Project Success, a program of modified interdisciplinary instruction coordinated with special services, is considered to be consistent with the theory of individual differences and individualized instruction which is inherent in the philosophy of Bloomington Public School's educational goals and objectives. The project, which began as an alternative program for grades 10-12 in September 1969, completed its fifth full year of operation in June 1975. The stated rationale which guided the general direction of this alternative program has been to implement strategies of instruction designed to: provide success oriented learning alternatives consistent with the needs of students; avoid labeling students as incapable nonlearners and as social outcasts; remove biases within the school which impede positive youth development; provide an opportunity for students to make a transition from the alternative program to the regular program; provide the opportunity for vocational training or work experience during their high school careers; and provide alternatives among the elective courses that will provide a wide range of interdisciplinary experiences. This report focuses on data collected as it pertains to the present 12th grade students who have elected to remain in project classes throughout three years of senior high school. (Author/JM)
