The work of the Menzies School Leadership Incubator suggests we need a new approach to leadership that supports school leaders to better manage transformational change and deepen collaborative capacity necessary to cultivate collective efficacy to improve student learning outcomes. This paper provides a description of the work of the Menzies School Leadership Incubator (“the Incubator’) and insights generated so far. The Incubator has identified five leadership domains which underpin the leadership of Collective Efficacy; Understanding Collective Efficacy Systems; Leadership Change; Leadership Team, and Leadership Collaborative Capacity.
