It is 10 years since the Gallup Leadership Institute’s Summit was held to stimulate ideas around the emerging field of Authentic Leadership. The gathering took place to investigate what might be a key construct underlying all positive forms of leadership, which they labelled Authentic Leadership Development (ALD). Over 80 papers were presented and key articles then published in a special edition of The Leadership Quarterly and a volume of Monographs in Leadership and Management. This paper briefly overviews the field, focusing on the part coaching psychology can play in the development of Authentic Leaders. It specifically discusses a group-coaching approach to Authentic Leadership and examines the humanistic conditions that are believed to play a significant part in its effectiveness.
