A concise description of an objective method for allocating San Jose students into groups so that each group includes the same representation of two quantitative measures of scholastic achievement. The conditions provided that each group be internally heterogeneous, and that intergroup differences be small, so that each represented a separate replication of the same experiment. The purpose of the allocation was to mirror uniformly the central tendency and variability of the overall student population. The method could apply to a more flexible set of initial conditions: it could accommodate another variable; it would be equally useful for ensuring representation across socioeconomic or cultural variables; and it obtains proportionality with the racial-ethnic mix of the student population considered. 11 pp.
