Scientific research involving children and adolescents as members of research teams are relevant, both because of the possibility of giving voice and leading role to this social group and because it constitutes an expressway of exercising the participation rights enshrined in the Convention on the Rights of the Child (CRC). Increased research involving children and adolescents as co-researchers appears, seeking designs and implementations that safeguard technical, cultural, and ethical aspects. This article reports a methodology implementation of children as co-researchers in a scientific research project associated with school engagement and its contextual factors in Chile. Therefore, the article goes in-depth into the methodology implementation, the conditions of the implementation, and its results. Finally, conclusions and projections for future research in this line are shared.
