This book provides an internationally comparable set of indicators on educational provision for students with disabilities, learning difficulties and disadvantages (DDD). It highlights the number of students involved, where they are educated – special schools, special classes or regular classes – and in what phases of education – pre-primary, primary, lower secondary and upper secondary education.  It also includes information on the physical provision and on student/teacher ratios and discusses policy implications concerning special education. This new edition also presents for the first time trends in the data for students with DDD from 1999 to 2003.
