This research, led by the National Children’s Bureau Research Centre and in partnership with The Children’s Society Research Unit, the Alliance for Inclusive Education and The Council for Disabled Children aims to provide the evidence to support the development of disabled children and young people’s participation in England. It is a three and half year project funded by The Big Lottery Research grants programme (July 2010 until Spring 2014). The project has a number of related components and benefits from the full involvement of 16 disabled young people who are advisors and coresearchers and have worked alongside the research team at all stages of the project. The young people created the name VIPER for the project to reflect what the research was about and what they wanted to achieve for other disabled young people. VIPER stands for Voice, Inclusion, Participation, Empowerment and Research. Vipers used the literature review findings to inform the development of project and in particular to inform questions for the qualitative research phase. They have also used evidence from the literature review in the development of their policy and practice recommendations.
