This article reports findings from an exploratory study of how learning support and resource teachers perceive each other's role. The study was conducted during the debate on the proposed changes to allocation and deployment of support teachers, following the publication of Circular 24/03 by the Department of Education and Science. It sought to test the hypothesis that learning-support and resource teachers perceive each other's roles differently in terms of their distinctiveness, type of children they support, working arrangements and training. The findings confirmed this and the implications of this for more whole-school collaborative models of support are discussed. (Contains 1 table and 3 figures.)
