This framework for an Autism-Friendly School is grounded in the findings of a comprehensive research study conducted over a 2-year period between 2023 & 2025. The study captured the missing voices of primary and post-primary school-aged autistic children about their experiences of inclusion in education in the Republic of Ireland. Parents and school staff also informed the study. A summary report, including policy recommendations, and a number of peer reviewed publications (in progress) have emerged from this research, in addition to the framework. The purpose of the framework is to serve as a practical resource for schools to help them to embed an autism-friendly culture in their school. Ten principles as set out below have been developed from the themes emerging from the study. These principles could be adopted by any primary or post-primary school with minimal cost. Each of the principles are underpinned by a series of specific actions. These actions are examples of how the ten principles could be embedded within schools but they are not exhaustive, as each school will have their own specific contexts and can add further actions to the list provided.
