"Adolescent Prejudice" by Glock, Wuthnow, Piliavin, and Spencer was the central focus for the conference at which this paper was presented. The first objective of this paper was to discuss the implications of that research paper for the social systems characteristics of schools. It was observed that to a considerable extent adolescents form ethnic stereotypes in response to certain educational processes to which they are subjected. These processes operate so as to allocate better or worse educational outcomes to different students on the basis of their ethnicity. The second objective of this paper was to focus specifically upon the ways in which these educational processes might be changed in desegregated schools to reduce ethnic prejudice. These processes are of two types. The first type, Status Ranking processes, tend both to separate the students into distinct groups according to ethnicity and to produce better academic outcomes for one group--the Anglo-Americans--at the expense of the others-- e.g. Blacks, Mexican-Americans, etc. The second type of processes, Status Equalization processes, tend to integrate the students into a single group, regardless of ethnicity and to produce good educational outcomes for all students.
