Quantitative and qualitative research methods combining case study methodology with numerical analyses were used to investigate the desegregation of Hispanics in selected school districts. Survey responses were analyzed in the areas of English language instruction, special education programs, discipline, grade retention, and staffing patterns. It was concluded that: (1) Hispanic isolation from blacks will probably continue to increase; (2) Hispanics are becoming more isolated from whites and, in many tri-ethnic communities, Hispanic segregation from whites and blacks is increasing in unpredictable patterns; (3) the juxtaposition of bilingual education vs. school desegregation as an either/or option is detrimental to the implementation of school desegregation in Hispanic communities; and (4) at present rates, Hispanics will become the most segregated racial group in the 1980's.
