This literature review has been commissioned by the Te Ariki Trust so that future applicants for the David Stewart Memorial Postgraduate Scholarship may benefit from access to a select literature review in order to understand the essence of the Trust’s four values. These four values underpin all work associated with the Trust. The intention of the scholarship is that it will provide a postgraduate study opportunity for a school leader to advance and honour the work of David Stewart. The aim of the review is to provide a repository which can be consulted when applicants consider how they might build on David Stewart’s legacy as they devise their scholarship proposals.
