Fifty lower-class Boston Negro students and 70 middle-class white suburban students ranging in age from 8 to 13 in grades 3 through 6 attended a suburban summer school in 1965. Boston students who were considered behavior problems did not qualify for the program, and all suburban students had volunteered to participate. Data were collected from teachers, students, and nonparticipating volunteer observers to evaluate the amount of the students' classroom participation and interracial social contact and the effect of the program on their knowledge about occupations and vocational goals. It was found that all the students participated actively, suburban girls less than the others, and that race was not a factor in their social interaction; however, because the two groups did not initially differ markedly in their occupational information or in their vocational goals, no conclusion could be reached about the effect of the program in this area. The students' achievement gains were not evaluated. (EF)
