Since 1964, Oberlin College has conducted a "special opportunity program" for post-seventh graders from deprived backgrounds. Each year approximately 65 students have been brought to the campus for an intensive period of educational, artistic, and recreational experience. This report concerns the post-program educational attainments of the first three summer groups, a total of 195 students. Schools in St. Louis, Mo., and Cleveland, Lorain, Elyria, and Oberlin, Ohio were asked to nominate twice as many individuals from culturally deprived or poverty backgrounds who had some likelihood of success as the program was able to accept. From each school's list pairs were matched as closely as possible, and one from each pair was randomly selected to participate in the program. This study tried to determine whether the summer experience, plus the follow-up contacts with the Special Opportunity staff, significantly improved the likelihood of a person staying in school, attaining good grades, and for the 1964 group, of entering college. Significance was measured against the performance of the randomly selected controls. This report also describes the method that was used for taking account of the quality of the match and examines the importance of networks of "significant others." (AF)
