Difficulties exist in identifying and providing services for children with social, emotional and behavioural difficulties (SEBD). As teacher referral is an essential link in service delivery this study investigated teachers' current perceptions of SEBD by examining characteristics of children nominated by their teachers as having SEBD. While the majority of children were nominated for externalizing behaviours, teachers rated girls as having more severe externalizing difficulties than boys. In contrast, there was no significant difference between teachers' internalizing ratings of boys and girls, despite the fact that girls reported more severe depressive symptomatology. Moreover, teachers rated gender-contrary behaviours more severely than gender-consistent behaviours. Consistent with achievement results, teachers rated the majority of children as having moderate to severe academic difficulties. Little agreement was found between characteristics reported by teachers and children. Implications are discussed within the context of the school psychologist's role in working with teachers to increase awareness of the profile of these children. (Contains 2 tables and 3 figures.)
