Learning disabilities definitions and criteria used by state education departments

This article reports the results of a survey of the 51 state departments of education (including Washington, DC) regarding their definitions of learning disabilities, identification criteria, and operationalization procedures. A conceptual framework consisting of eight components was used in analysing the definitions and identification criteria, Results show the continued effect of the 1977 federal definition and criteria while revealing variations in state definitions and criteria, For example, several state definitions now include the neurological component, and use of discrepancy criteria is increasing, To determine current trends, the data are compared with those from a similar survey published in 1990. Findings are discussed in terms of trends, prereferral interventions, and noncategorical identification.
