The purpose of this longitudinal study was to understand the relationship between children on the autism spectrum, subtypes of autism, experiences of intervention, and school support with developmental and behavioural trajectories.

This collection now comprises six years of data and is one of the world's largest and longest studies following children on the spectrum over time. The study explored academic achievement and participation over time, with data collected from home, school and from some of the children/teenagers themselves.

We thank all our families, teachers and schools for their time and insights throughout this study. A short thank you video summarising the research is now available.

Longitudinal data from this study will be made available for approved future research purposes through the Australian Autism Biobank in late 2022.
