The organisation Achievement for All engaged in international projects in England, Latvia, Lithuania, Norway, South Korea, the United States of America and Wales with the aim of raising the aspirations, access and achievements of vulnerable and disadvantaged children and young people. These projects were united in bringing Special Educational Needs and Disability (SEND) back into the classroom by focusing on the relationship between parents, leaders, teachers and wider professionals. Achievement for All in International Classrooms examines these projects, looking at the context of each and the research findings, before considering how this could enhance knowledge and understanding in other international settings. Sonia Blandford examines the policy implications needed to bring SEND into the classroom, understanding of the scale of the issue, moral purpose, belief, commitment, collaboration and determination, through evaluation, research and practice. She also considers what it takes to change practice, bringing Achievement for All and SEND into the classroom, looking in particular at the implications for: - Leadership - Teaching and learning - Parent and carer engagement - Wider outcomes and opportunities - Professional development for all staff Drawing on her wealth of experience and expertise, Blandford then makes recommendations on what it would take to introduce Achievement for All in policy to bring SEND into the classroom, with particular reference to changes at national, regional and school level, as well as parental and carer engagement and a desire to improve outcomes for all children and young people.
