This article presents a study of the use of Immunity to Change (ITC) coaching in an integrated leadership development programme as an example of awareness based leadership development technology. Constructivist developmental theories of leadership, self-awareness and the use of ITC coaching are reviewed. Findings from interviews with eight ITC coaches revealed a process of movement from embeddedness and a socialized mindset to detachment and evidence of an emerging self-authoring mindset. Discussion leads to conclusions that the ITC coaching process can make a significant contribution to leadership development.
