Schools have been identified as well placed to support students' wellbeing and encouraging the active participation of children and young people in school life is in line with current English legislation. Student-led research has the potential to create a positive, long-lasting impact. This evaluative systematic literature review (SLR) sought to identify the?features of?effective student?participation?in the co-production?of?whole-school?wellbeing?strategies, with a focus on Participatory Action Research (PAR) projects. Ten papers published between 2011 and 2021 were identified using the PRISMA framework and evaluated for methodological quality and appropriateness of focus. Several factors were identified as impacting on the success of PAR, including group composition, power balance, and sustainability. The paper concludes that carefully planned PAR projects can result in successful collaboration with students to develop whole-school strategies for a range of issues/topic areas. Further research evaluating the long-term impact of such projects on whole-school practice is warranted.
