The academic achievement and social functioning of children with learning difficulties (LD) and children without LD (7-12 years old) was examined. Attainment scores in mathematics and English were obtained for each child, and a sample of children without LD was further classified as low achieving (LA) or high achieving (HA) on the basis of these scores. Sociometric and peer behavioural attribute scores were collected for each child. Findings indicated correlations of attainment with sociometric status and also with behaviour attributes. Boys and girls differed on the proportion of variance in sociometric status accounted for by academic achievement and also by various behavioural attributes. HA children scored higher on positive sociometric status than children with LD, and higher on positive behaviours than both LA children and children with LD. Children with LD scored higher on negative behaviours than both HA and LA children. The findings are discussed as indicating a relationship between academic achievement and social adjustment, suggesting that intervention strategies need to target social relationship difficulties in LA children as well as children with LD, while also accounting for possible gender differences. Behavioural descriptions used in peer nominations of children's social behaviour is appended. (Contains 5 tables and 1 figure.)
