The growth of service-learning as an educational approach in colleges and universities has led to the use of more advanced pedagogical techniques in service-learning programs. This article describes a financial literacy service-learning program that a team of undergraduate business students completed while following a participatory action research perspective in the planning, implementation and measurement of a financial literacy event for high school students. This approach fits in the literature on ethics, financial literacy and service-learning and provides an illustrative example of how to incorporate this participatory action research perspective into future financial literacy service-learning initiatives.
