The idea of collaborative knowledge production has entered the discourse of different disciplinary fields. Still, there is some confusion as to how to assess phenomena and projects based on a multifaceted understanding of research; such confusion indicates too a methodological conflict between academic and other approaches. This article takes advantage of a concept of art education that incorporates knowledge production as a relevant pillar of artistic production, including methodologies, methods and tools of community-based research and socially engaged artistic research. First, we clarify the links among different state-of-the-art concepts of socially engaged art-based research, community research and citizen science, and then offer insights into a case study of a socially engaged art-based project. Within this context, we focus on the potentials of socially engaged arts-based research in art education and citizen science. Second, we ask how criteria regarding community- and arts-based research might function. Third, and finally, we also aim to clarify the links between socially engaged arts-based research, community-based research, qualitative inquiry and art education. Beyond these, the article also questions appropriate forms of assessment.
