ABSTRACT
This article identifies certain cultural assumptions that underlie special education policy and practice in the United States, and argues that unawareness of cultural relativity contributes to considerable cross-cultural dissonance in working with families from diverse backgrounds. With regard to policy, the article argues that, despite an ideal of parental participation, the medical note on which the law is based frequently results in misunderstanding between professionals and parents who do not share the same value system. Three aspects of such misunderstandings are explored: The way disability is defined, the power accorded to professional expertise, and the commitment to the decontextualized language of objective science. With regard to practice, the article further identifies four areas of parent-professional dissonance: Beliefs about parenting styles, education goals, family and community concerns, and the pragmatics of communication. Explicit awareness of cultural relativity is recommended as an essential step towards reciprocal relationships with families from diverse backgrounds.
