Factors influencing the identification of black and white students with learning disabilities

This study examined the differential influence of an IQ cutoff and standard score or regression-based method for determining a severe discrepancy as eligibility criteria for the identification of black and white students with learning disabilities. Subjects were 218 white and 132 black students referred for possible learning disability services. The results of the study demonstrated that the use of a standard score method for determining a severe discrepancy and the use of an IQ cutoff above the range for mental retardation resulted in the disproportionate underrepresentation of black students meeting eligibility criteria. In contrast, when a regression-based method to determine a severe discrepancy was used, along with the absence of an IQ cutoff, no differences were discerned between the two groups. The implications of these findings for current practice are discussed.
