Project ABC is a precollege talent search program that provides academically able, motivated disadvantaged youth with scholarships to private secondary schools, after an intensive summer transitional program. In an evaluation study of 82 disadvantaged boys, predominantly Negroes, who entered in the program in 1965, it was found that (1) the boys' academic records ranged from complete failure to outstanding success, (2) test-retest data on the Otis I.Q. and Cooperative English tests showed that the boys made no appreciable gains over a 2-year period, (3) overall the students made a satisfactory school adjustment, and psychological inventory scores showed statistically significant changes for the boys, who seemed to become more tense, yet more self-assured, (4) social adjustment and academic performance were highly correlated (.56), and (5) by the beginning of the fourth year 26 percent of the boys had dropped out, 60 percent for academic reasons and 40 percent for adjustment difficulties. The research design included similar testing and evaluation of a comparable group of disadvantaged students who remained in their home high schools.
