The lack of student engagement in school has been studied from different approaches. Participatory methods are gaining acceptance and relevance in educational research because they respond to both ethical and validity concerns. Since youth engagement in participatory research should not be taken for granted and may overlap with student engagement in studies in schools, this article presents an analysis of adult researchers' and young co-researchers' field notes, journals, and reports of an ethnographic participatory research about learning in and outside school carried out in five secondary schools with 35 students. Findings show the different perceptions of youth engagement between young and adult researchers and how youth agency and autonomy may be more easily desired than recognized by adult researchers.
