Little is known about the professional learning of experienced school principals in New Zealand. How do they maintain sufficient learning to meet a diverse and fluid variety of leadership expectations after at least five years as principal? This research examines the professional learning habits and preferences of fifty two experienced school principals from a variety of schools covering subgroups of Years 1 – 13 within the Waikato and Bay of Plenty regions. A self-selected self-administered survey elicited responses on their use of over twenty three potential sources of learning. This approach was used to provide a fresh look at an under-researched topic. Research findings demonstrate that respondents used all learning sources to varying degrees according to factors such as personal preference, availability, cost, perceived quality, time and distance. A single best practice model remains elusive; those surveyed adopted eclectic approaches to their professional learning. The impact of information technologies and the role of professional principals’ associations in monitoring, promoting and supporting principals’ access to high quality professional learning are also discussed. Consideration of links between survey data and existing theory has resulted in the development of a framework of learning platforms for experienced principals. In addition, a number of dualities are highlighted. Together the proposed learning platforms and dualities provide a conceptual mechanism for the planning of deliberate professional learning and directions for further research.
