Autism Evaluation in Mississippi: 2026 Guide
An autism evaluation in Mississippi happens through one of three channels. Private clinics produce a clinical diagnosis and typically book 9 to 24 months out. Early Intervention serves children under 3 and is built on federal IDEA Part C deadlines. The public school child-find process serves ages 3 and up and runs on a 60 calendar day federal evaluation clock. None of these pathways are mutually exclusive.
The three pathways for an autism evaluation in Mississippi
1. Early Intervention (under age 3): First Steps Early Intervention
Free, no diagnosis or doctor referral required, federally guaranteed under IDEA Part C. First Steps is administered by the Mississippi State Department of Health, the lead agency for Part C of IDEA, and operates through nine Local Early Intervention Programs across three regions. Per the federal Part C rule, evaluation, assessment, and the initial IFSP meeting must occur within 45 calendar days of referral. Parents and providers can submit a referral by calling the Jackson-area Central Referral Unit at 601-576-7427 or toll-free at 1-800-451-3903. Services typically begin within 30 days of the signed IFSP.
Self-refer to First Steps Early Intervention →2. Private developmental pediatrician or autism clinic
Typical waitlist in Mississippi: 9 to 24 months. Cost with insurance: Copay or coinsurance after deductible varies by plan; behavioral therapy including applied behavior analysis covered under Miss. Code §83-9-26, with statutory limits of 25 hours per week of ABA through age 8 (extensions beyond age 8 require a medical necessity determination). Without insurance: $1,500 to $4,500 for a full diagnostic battery; the Center for the Advancement of Youth at UMMC and the MIOD Autism and Developmental Disabilities Clinic are typically lower-cost than out-of-network neuropsychology.
Children's of Mississippi at the University of Mississippi Medical Center (UMMC) in Jackson runs the Division of Child Development and the Center for the Advancement of Youth (CAY), which use a multidisciplinary developmental pediatrics model with telehealth statewide reach. The Mississippi Institute on Disabilities (MIOD) Autism and Developmental Disabilities Clinic at Mississippi State University serves the eastern and northern parts of the state. The Munro Regional Center and DD/MR Community Mental Health Centers (regional) provide initial developmental screening. Jackson waitlists typically run longer than the Mississippi Gulf Coast satellites.
3. School district evaluation (age 3 and up)
Free, federally guaranteed under IDEA Part B (Child Find). Submit a written request for an initial evaluation to your district's Director of Special Education or your child's principal. Mississippi school districts must convene a Teacher Support Team or referral committee within 14 school days of receiving the request to consider the referral and obtain written parental consent before beginning the evaluation. The 60 calendar day clock begins when the school district receives signed parental consent for assessments.
Timeline: Per Mississippi State Board Policy 7219 (implemented at Miss. Admin. Code Title 7, Part 3, Chapter 74), the initial evaluation must be completed within 60 calendar days of receiving written parental consent for the evaluation. This matches the federal IDEA Part B baseline at 34 CFR §300.301(c)(1)(i). Exceptions apply if the child moves between districts during the process, if the parent fails or refuses to make the child available, or if the parent and public agency agree in writing to extend the timeline for a specific learning disability evaluation using a Response to Intervention process.

Insurance mandate
Yes. Mississippi's autism insurance mandate is codified at Miss. Code §83-9-26, enacted by HB 885 of the 2015 Regular Session and effective for policies issued or renewed on or after January 1, 2016. State-regulated plans must cover screening, diagnosis, and treatment of autism spectrum disorder, including applied behavior analysis, up to 25 hours per week through age 8. Coverage beyond age 8 may be extended under an ongoing treatment plan when medical necessity is established. The mandate does not apply to grandfathered individual and small group plans subject to ACA essential health benefits.
Medicaid waiver: Mississippi Intellectual Disabilities/Developmental Disabilities (ID/DD) Waiver, administered by the Mississippi Department of Mental Health, Bureau of Intellectual and Developmental Disabilities, with Medicaid eligibility through the Mississippi Division of Medicaid
Mississippi residents of any age with a diagnosis of intellectual disability, autism, or a related developmental disability who meet ICF/IID level of care criteria. The applicant must be Medicaid-eligible (typically through SSI or the 300% SSI Special Income Standard). Services include in-home respite, day services for adults, supervised living, support coordination, supported employment, behavior support services, crisis intervention, and therapy services. To start, families schedule an evaluation through their regional ID/DD program at the Department of Mental Health. // VERIFY 2026-05-18: Mississippi Autism Advisory Committee reports (2023 and 2024) indicate roughly 680 individuals with autism among approximately 2,500 to 2,600 people on the ID/DD Waiver Planning List with an approximate nine-year wait, but a current snapshot tied to a single .gov page could not be retrieved through automated fetch. Note: the waitlist for full waiver enrollment in Mississippi is currently around 9 years; apply early.

Frequently asked questions
- How long is the autism evaluation waitlist in Mississippi?
- Private autism evaluations in Mississippi typically take 9 to 24 months from referral to evaluation date. The state's Early Intervention program (First Steps Early Intervention) is faster for children under 3, with evaluation completed within 45 days of referral by federal law.
- Can the school evaluate my child for autism in Mississippi?
- Yes, for children age 3 and up. Submit a written request for an initial evaluation to your district's Director of Special Education or your child's principal. Mississippi school districts must convene a Teacher Support Team or referral committee within 14 school days of receiving the request to consider the referral and obtain written parental consent before beginning the evaluation.

Exceptions apply if the child moves between districts during the process, if the parent fails or refuses to make the child available, or if the parent and public agency agree in writing to extend the timeline for a specific learning disability evaluation using a Response to Intervention process. A school eligibility determination of "Autism" qualifies the child for an IEP and special education services, but it is not the same as a medical diagnosis from a developmental pediatrician (which insurance and Medicaid waivers may require separately).

- Do I need a referral from my pediatrician to start in Mississippi?
- No, not for First Steps Early Intervention (Early Intervention). You can self-refer directly using the program's referral page. For private clinics, some require a pediatrician's referral form for insurance billing; many do not. Always call the clinic to confirm before joining the waitlist, since being on the wrong list wastes months.
- My child is on a long waitlist in Mississippi. What can I do right now?
- Three things, in order. First, refer to First Steps Early Intervention (under 3) or your school district (3+); these run on legal deadlines, not waitlists. Second, document what you see at home (videos, behavior patterns, sleep, sensory triggers) so the eventual evaluation has data to work with. Third, start no-diagnosis-required supports: visual schedules, sensory accommodations, predictable routines. Our free 30-day plan tool combines all three based on your specific situation in Mississippi.
