The use of high-impact practices is well documented in higher education literature. This brief describes the integrative practice of undergraduate peer-led leadership learning communities as a model of delivery within a large introductory leadership education course for first-year students. Utilizing open-ended questions embedded within end-of-semester teaching evaluation surveys, we analyzed students' perceptions of the learning community experience and the peer leader's role. Our findings illustrate how peer leaders play a critical role in fostering a vibrant leadership learning community, which contributes to students' positive perceptions of their own leadership learning and development.
