Kim SH, et al. - Experts aspired to investigate early predictors of and changes in school-age academic achievement and class placement in children referred for autism spectrum disorder (ASD) at age 2. Many children with ASD achieved basic academic skills commensurate with or higher compared to their cognitive ability. However, for learning difficulties, more rigorous screening could be important for those with average cognitive skills because a significant minority indicated relative academic delays. In early treatment, interventions targeting cognitive skills and parent participation could have cascading effects on long-term academic development.
