The research reported in this paper focuses on the process of involving students as co-researchers in schools. The study involved a process of collaboration with two secondary schools in an economically deprived city in the north East of England. Use was made of a framework for developing inclusion that emerged through earlier work. The framework has students' voices at its centre. Through an analysis of the research process, factors that are important when involving students as co-researchers in schools are discussed. The understandings gained through the study have implications for future research. It is argued that such approaches, which place students at the heart of the research process, can be viewed as a matter of inclusion.
