The researcher explored the impact of a student voice initiative (SVI), the Student Ambassador Council (SAC), on the social-emotional competencies (SECs) of middle school, 5th-8th grades students. Drawing upon the principles of youth empowerment, more specifically Youth Participatory Action Research (YPAR), and social-emotional learning (SEL), the SAC provided a platform for students to actively participate in decision-making processes within their school community. The researcher employed action research using a mixed methodologies approach, combining surveys, interviews, and participant observations to gather data on students' experiences and perceptions of the SAC. Quantitative analysis of pre- and post-surveys did not reveal significant improvements in students' SECs following their participation in the SAC. However, qualitative data from open-ended questions on the post-survey, interviews and observation provided further clarity demonstrating the initiative fosters growth in students' perceptions of Student Voice, Social Awareness and Self-Efficacy in addition to student development in confidence, self-directed learning and civic engagement. Moreover, the study also suggested broader implications of the SAC on school climate and administrative practices. Findings suggested that SVIs like the SAC contributed to a more positive and inclusive school environment, promoting greater collaboration between students and school staff.
