Developing leadership, sustainable leadership is a huge issue in education and will become even more significant. All over the world, as the “baby boomers” near the ends of their careers, we have large numbers of senior, respected administrators retiring. A lot of us came in on that same wave several decades ago. They were exciting times. What benefitted us was mentoring, support and direction. It is now up to us to ensure that our younger successors develop the confidence and the competence to be able to sustain change in their schools.
