This document contains 10 units organised as in-service training (INSET) sessions, each of which can be used singly or as part of a continuing programme of work. Although the document is arranged in a logical sequence, it is not necessary to use the units in order. Each is designed to be free-standing and could be used alone to meet a particular need identified by teachers. Units summarise current thinking on the most effective ways to teach and to achieve progression in writing, using available research and resources to provide a comprehensive one-stop shop for teachers in Wales. Clearly, a document of this kind cannot provide much more than the main.
