A nationally representative sample of 20,614 eighth grade students was
examined for bias in placement decisions for children said to have le
arning disabilities. Factors investigated for bias were race, sex, and
socioeconomic status. Path analysis showed significant and direct pat
hs from sex and race to placement, controlling for socioeconomic statu
s, academic ability, and behavioral competency. Boys were overrepresen
ted in such classes beyond what their somewhat lower academic and beha
vioral competencies would predict. Caucasians were similarly overrepre
sented controlling for other variables in the model. It appears that b
oys and Caucasians are overrepresented in learning disabilities placem
ents on a national scale even when other contributing factors are cont
rolled.
