This paper offers some insights into the ways in which networks of schools can work together in order to bring about school improvement. These activities are based on the Unesco teacher education strategies and the use of The Index for Inclusion (2002) as a vehicle for school inquiry purposes. These inquiries lead to a focus on classroom practice development and school policies and cultures that aim to reduce barriers to participation for all students. It focuses on key themes that have been seen as important in successful developments and more inclusive practices. It also offers 'school stories' illustrating how individual schools undertook their inquiries
