According to Frankenberg, Lee, and Orfield, segregation for black students declined substantially after the landmark 1954 U.S. Supreme Court decision, "Brown v. Board of Education," reaching its lowest point 30 years later. By comparison, Latino students have experienced "steadily rising segregation since the 1960s." Unlike black students who have been the focus of desegregation orders and Office of Civil Rights enforcements, Latinos have remained segregated both because of limited policy efforts on their behalf and because of their increasing numbers. In this chapter, the authors focus on the educational challenges of linguistic isolation for Latino students by examining the case of California. They provide a historical overview of Spanish in California, tracing the climate of evolving hostility toward Spanish and Spanish-speaking immigrants, and describing the challenges of achieving equity for Latino students segregated by language. The authors address four objectives that are of paramount importance in the challenge of reintegration. (Contains 5 tables, 7 figures, and 9 notes.)
