The paper reflects on the meaning and scope of the inclusive research or research on the inclusive education, in line with the analysis of the different methodologies or approaches that could be apply to any research in the field of education. The authors positioned themselves beside the critical approach that contributes to reduce the discrimination that many students experience before, during and after their schooling. It is also discus some of the meanings or perspectives from which address the inclusive education and summarizes some of the main results and knowledge available to understand and improve it. The authors argue that there is needed to promote a kind of research that contributes to building inclusive knowledge, both in the process and the results and impact, but also point it out the paradox that there is already enough knowledge to transform school cultures, policies and classroom practices to be more inclusive.
