The Individuals with Disabilities Act (IDEA) was most recently revised in 2004 (and, in fact, renamed the Individuals with Disabilities Education Improvement Act, but most people still refer to it as IDEA). The law mandates that the state provide all eligible children with a free and appropriate public education that meets their unique individual needs.
The IDEA specifies that a child is legally entitled to receive early intervention services or special education services if the child meets the state eligibility requirements that define disability. Autism is specifically considered a disability. if your child has been diagnosed with ASD, it constitutes that you are entitled to the services provided under IDEA.
The IDEA establishes an explicit role for you as a parent in planning and monitoring your child’s individual education program. You are entitled to be treated as an equal partner in deciding on an educational plan that contains the elements that your child needs. As a parent you are entitled to decisions made in treatment, but also you bare the responsibility to insure your child is receiving appropriate services to make educational progress.
