The intent of this study was to determine the behavioral differences in information processing between children failing in the elementary grades who are of primary school age and those of intermediate school age. The data showed that similar factorial clusters appeared for both subject age groups, but that the levels of loading were different. The difference between the principal components for the subject groups occurred for perceptual behaviors and not language behaviors. The implication is that prescriptive teaching techniques will need to be selected on the basis of both the age and compensatory behavioral strengths of the children.
