This paper aims to contribute a framework for EPs to draw upon when working with schools and organisations where support is needed to facilitate change at group and organisational levels. A critique is offered of in-service training (INSET) and its use of an approach for facilitating organisational change, which considers supporting factors and barriers. The introduction of an Implementation Framework gives guidance to educational psychologists in their planning discussions with schools and other stakeholders. This can support discussion about a range of ways EPs can work (beyond training) to help facilitate change at different levels. Research and literature informing the development of the Implementation Framework is shared as well as examples of the application of the framework in practice within an educational psychology service.
