This is a report of a forty-four month investigation in which three curricular approaches to rehabilitating school dropouts were evaluated under experimental conditions. Program participants were school dropouts between the ages of 17 and 22, and the program was conducted in a large urban high school. The findings of the study were: (1) significant differences in academic achievement were found in only three of ten comparisons between students who received academic and/or vocational training and those who did not; (2) returning to a school situation had no significant effect on students' social-psychological characteristics; (3) there were no significant performance differences between groups receiving only vocational and those receiving academic and vocational training; and, (4) during a two-year followup, the treated groups exceeded the control group in securing employment and annual earnings. No cluster of predictor variables was identified. It was concluded that vocational training prepared participants to find and more continuously hold employment. (Author/DM)
