A comprehensive guide to the whole field of SEN, focusing on the current UK legislative, institutional and educational frameworks. The author has gathered a wide range of information essential to good SEN practice in mainstream and special schools, including legislative changes. A classified or thematic index helps the reader plot a course though topics of current interest. The alphabetical entries cover six broad themes: basic terms, ideas and values; venues relating to special education and school organisation; roles, duties and responsibilities, procedures and rules; individual differences among learners with SEN; cuurriculum, assessment and resources; and pedagogy.
