The identification of high-school dropouts identified as learning disabled: evaluating the utility of a discriminant analysis function.
This study examined the utility of a linear discriminant function to distinguish between students identified as learning disabled (LD) who had either been released from high school under codes suggestive of school dropout (n = 213) or graduation (n = 92). The discriminant function was comprised of six variables--student ethnicity, reading ability, family intactness, family socioeconomic status, school transfers, and school-initiated interruptions. The analysis determined that differences between the LD dropout sample and LD graduate sample were sufficient to allow for a discrimination between the groups. On the basis of group differences the discriminant function that was constructed correctly classified 83% of the school dropouts and 46% of the school graduates, for an overall 73% accuracy rate. Those factors contributing most to the function were the number of district-initiated interruptions, school transfers, and family intactness. Based on the findings, implications for school districts and future research are noted.
