The results indicate that heterogeneity of race and heterogeneity of family educational background can increase the achievement of children from weak educational backgrounds with no adverse effect on children from strong educational backgrounds.

The higher the social class of other students the higher any given student's achievement.

Grades are almost completely relative, in effect ranking students relative to others in their class. Thus extra achievement by one student not only raises his position, but in effect lowers the position of others.

The educational resources provided by a child's fellow students are more important for his achievement than are the resources provided by the school board.

In every school, more boys wanted to be remembered as a star athlete than as a brilliant student.

Cultural dominance of middle-class norms prevail in middle-class schools with a teacher teaching toward those standards and with students striving to maintain those standards.

It is clear from all these data that the interests of teenagers are not focused around studies, and that scholastic achievement is at most of minor importance in giving status or prestige to an adolescent in the eyes of other adolescents.
