The main purpose of this study is to identify the professional writing needs of undergraduate students studying social work in the University of Botswana. In order to do this, it seeks to analyse the types of texts produced by social workers in their professional setting, to find out what relationship exists between the writing done by professional social workers and the writing taught in the dedicated English Language Support unit at the University of Botswana, and to explore the similarities and differences between the documents written by the students and those produced by professional social workers. It also examines current approaches to teaching writing in the University, with the aim of identifying the writing needs of social work students and exploring how these can be effectively addressed.
