Autism Evaluation in Delaware: 2026 Guide

Frequently asked questions

How long is the autism evaluation waitlist in Delaware?

Private autism evaluations in Delaware typically take 6 to 18 months from referral to evaluation date. The state's Early Intervention program (Birth to Three 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 Delaware?

Yes, for children age 3 and up. Submit a written request to your district's Director of Special Education or building principal, or contact your district's IEP team chairperson. Per 14 DE Admin. Code §925-2.0 the LEA must obtain signed parental consent before conducting an initial evaluation. The evaluation clock starts the date the LEA receives written parental consent. Per 14 DE Admin. Code §925-2.0 (Section 2.3), the initial evaluation must be conducted and the child's eligibility for special education and related services determined within 45 school days or 90 calendar days of receipt of written parental consent, whichever is less. This is a stricter state amendment to the 60 calendar day federal IDEA floor at 34 CFR §300.301(c)(1)(i). The time frame does not apply if the parent repeatedly fails or refuses to produce the child for evaluation, or if the child enrolls in another public agency after the time frame has begun and before the prior LEA's determination. 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).

Who pays for autism evaluation in Delaware?

Early Intervention (under 3) and school evaluations (3+) are free. Private evaluations: copay or coinsurance after deductible varies by plan; behavioral therapy including aba covered under 18 del. c. §3366 (individual plans) and §3570a (group and blanket plans) for insureds under 21 years of age, subject to a statutory $36,000-per-12-month-period-per-person aba cap that federal mhpaea compliance limits in most fully-insured plans; $1,800 to $5,000 for a full diagnostic battery; wilmington academic specialty practices tend to run higher than community developmental pediatrics in dover or sussex county. Delaware's autism insurance mandate is codified at 18 Del. C. §3366 (individual health benefit plans) and 18 Del. C. §3570A (group and blanket health insurance), enacted by SB 22 of the 146th General Assembly (78 Del. Laws c. 398), signed August 13, 2012, with coverage required for plans delivered, issued, executed, or renewed on or after December 11, 2012 (120 days after enactment). State-regulated plans must cover the screening, diagnosis, and treatment of autism spectrum disorders for insureds under 21 years of age. Covered treatment includes habilitative and rehabilitative services (including applied behavior analysis), pharmacy care, psychiatric and psychological care, and therapeutic care. /* Quote (78 Del. Laws c. 398, verbatim from the enacting bill): "Coverage for applied behavior analysis services under this section by an insurer shall be subject to a maximum benefit of thirty-six thousand dollars ($36,000) per twelve month period per person." */ The statute imposes a $36,000 per 12-month-period per-person dollar cap on applied behavior analysis services and prohibits any cap on the number of visits to autism services providers; federal Mental Health Parity and Addiction Equity Act compliance limits the enforceability of the dollar cap in most fully-insured plans. Insurers are prohibited from terminating coverage or refusing to issue or renew coverage solely because the insured or a family member has been diagnosed with or treated for autism spectrum disorder.

Do I need a referral from my pediatrician to start in Delaware?

No, not for Birth to Three 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 Delaware. What can I do right now?

Three things, in order. First, refer to Birth to Three 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 Delaware.

What is the Delaware autism insurance mandate?

Delaware's autism insurance mandate is codified at 18 Del. C. §3366 (individual health benefit plans) and 18 Del.

Why is Delaware's school evaluation timeline different from the federal 60-day floor?

Delaware adopted a stricter state-level timeline that is more favorable to families than the federal IDEA minimum at 34 CFR §300.301(c)(1)(i). Per 14 DE Admin. Code §925-2.0 (Section 2.3), the initial evaluation must be conducted and the child's eligibility for special education and related services determined within 45 school days or 90 calendar days of receipt of written parental consent, whichever is less. This is a stricter state amendment to the 60 calendar day federal IDEA floor at 34 CFR §300.301(c)(1)(i). The time frame does not apply if the parent repeatedly fails or refuses to produce the child for evaluation, or if the child enrolls in another public agency after the time frame has begun and before the prior LEA's determination. In practice this means Delaware school districts have less room to delay than districts in states that mirror the federal 60 calendar day floor.

Does Delaware have a Medicaid waiver waitlist for autism services?

Delaware does not maintain a multi-year waitlist for its primary developmental disability Medicaid waiver. Delaware residents of any age with a documented diagnosis of intellectual disability, autism spectrum disorder, Prader-Willi syndrome, or a related developmental disability that originated before age 22 and produces substantial functional limitations. The Lifespan Waiver consolidated and replaced the prior DDDS waiver in 2017 and serves both children and adults; eligibility is based on the applicant's own income (TEFRA-style), not the parents' income. The DHSS DMMA Children's Community Alternative Disability Program (CCADP) provides Medicaid for severely disabled children at up to 250% SSI who do not qualify for SSI itself, with the child's own income and assets counted. // VERIFY 2026-05-18: a specific waitlist headcount for the Lifespan Waiver could not be sourced to a current .gov page; Delaware has historically described the program as non-waitlisted for individuals meeting the level of care criteria, but capacity and slot status may have shifted. Even with no waitlist, the eligibility and Medicaid determination process can still take months, so apply the day you have a diagnosis or strong evidence of substantial functional impairment rather than waiting.
