Positive education blends academic learning and student well-being. Although research and application in positive education is growing, most has involved psychologists and educators applying strategies in schools, with little research that involves student voices in the development and implementation of a school's positive education strategy. Assumptions are frequently made about what is best for student well-being, with little input from the students themselves. This paper describes a case study of participatory action research (PAR) carried out by students (N = 10) at a publically funded Australian school aiming to implement positive education. PAR is a form of collective inquiry undertaken by the people that the issue directly affects. The PAR group researched the school community regarding well-being during the school year. Mixed methods examined PAR student's well-being, self-efficacy, autonomy, social and emotional assets, and other competencies before and after the process. Student involvement allowed the school to better understand their students' well-being, and student-led communication about positive education laid the groundwork for its implementation. Results suggested benefits for the PAR students, particularly in engagement and self-efficacy. This realistically scaled study suggests that involving students using a framework of PAR is a promising, accessible, evidence-based, and developmentally beneficial approach to the implementation of positive education. © 2018 the author(s).
