States are requiring new types of training for educators working with children who have autism, providing fresh sources of funding for private school vouchers for these students, and undertaking new studies to try to address the needs of children with autism, a recent review by the Education Commission of the States shows.
The review is not meant to be a comprehensive list of everything states are doing, but even then, it's a fairly long one. The ECS looked at the issue in part because of how prevalent autism has been shown to be. The Centers for Disease Control and Prevention estimate one in 110 children have autism spectrum disorder. Some studies have shown it could be far more common.
