While an immensely rewarding role, the work of a school principal can be a lonely one, made up of brief encounters and regular interruptions, steep in responsibilities and accountabilities and free from accolades. Research shows that principals often feel there is nothing that really prepares them for assuming full and ongoing responsibility for a school. The I'm the Principal project utilised the Australian Professional Standard for Principals as a framework to consider key aspects and contributors to principal learning, action, influence and identity through interviews with 50 practising principals drawn from the various sectors and levels of Australian school education. I'm the Principal is a record of the study of the work of the principal today, containing personal, first-hand comments, experiences, values, beliefs and concerns. It speaks to the successes and the challenges of the role. I'm the Principal is a timely and thoughtful must-read for anyone wanting to explore and understand the value and worth of a school.
