An examination of physical growth was made for 46 school-aged twin children reported as having academic difficulties. Compared with matched controls, these children were found to have had a relatively slower rate of gain in weight during the first two years of life. Chronic or acute disease did not seem to account for the downward deflection in growth. The results suggest that appraisals of children with learning disabilities take into account deflections from growth parameters.
