Analyzes the application of levels of deficits or supports in the classification of mental retardation in published research. Analysis of data from three professional journals indicated that the supports model of classification has had no significant impact in subject descriptions reported in mental-retardation research. Implications for teacher…

Discusses the revised definition of mental retardation in a 1992 manual by the American Association on Mental Retardation.
