Prevalence of Learning Disabilities: Findings, Issues, and Recommendations. Research Report #20.
Bruininks, Robert H.; And Others
The authors discussed common approaches used to identify school children with learning difficulties, examined past studies on the prevalence of learning disabled school children, surveyed methodological and conceptual problems in identifying children with learning problems, and presented recommendations for future prevalence studies. Prevalence projections of learning disabled children in various elementary school populations were discovered to range from approximately 1 to over 30%. Surveys using achievement expectancy formulas were found to report lower percentages (between 4 and 15%) than speculative estimates by authorities and studies of children achieving below grade level. Differences in defining criteria, instrumentation, methods of analysis, characteristics of samples, and quality and extent of instructional history were thought to account for the wide variations in the characteristics of children with reported learning difficulties. Recommendations such as the following were offered: variables should be selected for possible inclusion into prediction equations which minimize potential content overlap between the predictors and the achievement measures, and the criterion of disparity between predicted and actual achievement should vary according to the length of time the students have been exposed to systematic instruction.
