Missouri's special education programs are administered by the Missouri Department of Elementary and Secondary Education (DESE) through its Division of Special Education. Missouri has developed a well-regarded Autism Spectrum Disorder (ASD) toolkit for educators and provides state-funded training on evidence-based practices through the Missouri Autism Guidelines Initiative, making Missouri a leader in autism-specific educational support.

Your Rights Under Federal Law

All autistic children in Missouri are protected by:

  • IDEA (Individuals with Disabilities Education Act): Entitles eligible children to a free appropriate public education (FAPE) in the least restrictive environment (LRE), including an IEP.
  • Section 504 of the Rehabilitation Act: Provides accommodations for students with disabilities that limit major life activities, even if they don't qualify for an IEP.

IEP vs. 504 Plan: Which Does My Child Need?

Missouri follows federal IDEA eligibility criteria, with autism spectrum disorder as a recognized qualifying disability category. Missouri's DESE has published autism-specific evaluation guidance that emphasizes a comprehensive, multidisciplinary approach to assessing the full range of a student's educational needs.

Most autistic children qualify for an IEP because autism typically affects educational performance requiring specialized instruction. A 504 Plan is appropriate for autistic students who can access general education with accommodations only (extended time, sensory breaks, preferential seating).

How to Request an IEP Evaluation in Missouri

  1. Write a letter to your child's school principal and special education director requesting a comprehensive educational evaluation under IDEA.
  2. Missouri's Missouri Department of Elementary and Secondary Education requires schools to complete the evaluation within 60 calendar days of parental consent, following the federal standard.
  3. If the school declines, they must provide written notice (Prior Written Notice) explaining why.

Sample request language:

"I am writing to request a comprehensive educational evaluation for my child, [name], under the Individuals with Disabilities Education Act (IDEA). I believe my child may have a disability that adversely affects their educational performance and requires special education services."

What to Expect at the IEP Meeting in Missouri

Missouri IEP teams must include: a regular education teacher, a special education teacher, a school district representative, a person who can interpret evaluation results, and the parents. The student may attend when appropriate.

The IEP must include:

  • Current levels of academic and functional performance
  • Annual measurable goals
  • Special education and related services (speech, OT, ABA if needed)
  • Least restrictive environment statement
  • Accommodations and modifications

Missouri-Specific Resources and Programs

  • Missouri DESE Division of Special Education: Provides parent guides, ASD toolkit, and procedural safeguards at the DESE website.
  • First Steps: Missouri's IDEA Part C early intervention program for children birth to age 3, operated through the Missouri Department of Health and Senior Services.
  • Missouri Parents Act (MPACT): Missouri's federally funded parent training and information center, offering free advocacy support, workshops, and IEP assistance statewide.
  • Missouri Disability Rights: Legal advocacy for Missourians with disabilities, including special education rights.
  • DESE Division of Special Education Complaint Section: Handles state complaints regarding IDEA compliance.

Filing a Complaint in Missouri

If Missouri schools are not following your child's IEP or 504 Plan, you have three options:

  1. State complaint: File with the Missouri DESE Division of Special Education — must be resolved within 60 days.
  2. Mediation: Voluntary, free process with a neutral mediator through DESE.
  3. Due process hearing: Formal legal proceeding before an impartial hearing officer through DESE.

Contact Missouri's DESE Division of Special Education Complaint Section for complaint procedures.

504 Plans in Missouri
