The social-behavioral competencies of learning-disabled (LD) students were compared with those of low-achieving and typical students. Three groups of 40 elementary age students from each of these categories were rated by their regular classroom teachers using the Walker-McConnell Scale of Social Competence and School Adjustment. The groups of learning-disabled and low-achieving students were both rated as having significantly lower levels of social competence and behavioral adjustment than the group of typical students from the general school population, but there were no significant differences in ratings between these first two groups. The present findings support the notion that social skills deficits constitute an important characteristic for much of the LD population. However, it is unclear whether social-behavior deficits constitute a characteristic that differentiates LD students from nonhandicapped students who are also low in academic achievement. The relationship between social-behavioral problems and academic achievement level is explored, and problems in selecting students for social skills training programs are discussed.
