This article examined Latina/o students' experiences of racism at El Centro High. Many felt that negative relationships with school personnel were deleterious to their education. These relationships had grown from teachers' and administrators' ideological assumptions of Latina/o students' racial inferiority. These assumptions had stemmed from two prevalent and deeply racist ideologies: One was that Latinas/os were an illegitimate presence in the United States, and therefore had no right to exist in the country or have any fair claim to service by U.S. institutions. The other was that Latinas/os lacked the intellectual capacity for school success.
