IDEA is the Individuals with Disabilities Education Act, which is a federal law passed in 1975. This law allows children with disabilities to receive a free evaluation to see if they have a disability and then entitles them to services if they are diagnosed with a disability. Early intervention services for children birth to 3 years old and special education services for ages 3-21 are provided for under IDEA.
Here is a link to organizations in MN that provide Early Intervention programs.
Your local school district will be your link to special education services. Here is a link to help you determine your school district in MN as well as another link here where you can fill in your school district and get their contact information.
