In order to research on effects of Peer Leadership activities at higher education, this study interviewed the 5 graduates which experienced peer-leaders at a university. The results of these investigations showed that they regarded the Peer Leadership experiences as the significance for their career. Some of them used the specific knowledge and skills of the experiences in their work environments, another who was a teacher at elementary school,applied the views of leadership learned by peer-leader’s lessons to his classroom. And they had kept their friendships among ex-peer-leaders, but they didn’t tell a lot about their juniors who were supported by them at a university. In addition, they might develop their career resilience by support activities at a university, because all of them told that they were supported by those around one in their work environments, and they empirically understood those supports might help them to develop their career.
