"Autism Spectrum Disorder (ASD) affects learning, social participation and daily function across the lifespan. Approximately 35,000 school-aged Australian children live with ASD; 95% of these experience educational restrictions. ASD has no known cure, and its causes are poorly understood due to the variability in how the disorder emerges and presents. Further, available treatments are only moderately successful and are not effective for all children with ASD. Knowledge about what (intervention) is likely to work for whom is missing from the field.
