This article builds on previous literature considering the role of educational psychology services in promoting whole-establishment nurturing approaches but with a specific focus on implementation within the early years context. It outlines work undertaken by Glasgow Educational Psychology Service (GEPS) to support the rollout of whole-establishment nurturing approaches within local authority early years establishments across the city. The article provides an overview of why nurturing approaches are crucial within early years establishments and how a successful whole-city implementation plan to support the professional needs of a complex workforce was developed. It also presents a professional development framework created by GEPS and shares helpful learning reflections for other local authorities and Educational Psychology Services looking to roll out similar whole-establishment nurturing approaches within early years settings.
