IEP Eligibility in Missouri: Who Qualifies?
What qualifies a child for an IEP in Missouri?
Missouri's eligibility criteria for special education are established in the Missouri State Plan for Special Education, Regulation III: Identification and Evaluation, and the DESE Compliance Standards and Indicators (Standards 600–2100). To be eligible, a child must: (1) be between ages 3 and 21; (2) have a disability as defined by IDEA and the Missouri State Plan; and (3) the disability must adversely affect educational performance such that the child requires special education and related services. Missouri uses a comprehensive multidisciplinary evaluation process; no single measure may be the sole criterion for eligibility (34 CFR 300.304(b)). For Specific Learning Disability (SLD), Missouri permits both the severe discrepancy model (at least 1.5 standard deviations between ability and achievement) and a response-to-intervention (RtI) process; Missouri does not require the discrepancy model. Any agency using RtI must have written procedures incorporating SEA-developed guidelines. For Young Child with a Developmental Delay (YCDD, ages 3–5), eligibility requires performance at or below 1.5 SD in two developmental areas or 2.0 SD in one area. Missouri's child find obligation requires districts to identify, locate, and evaluate all children with disabilities residing in the district, including homeless students, wards of the state, and students in private schools. The school district has 30 days from a parent's request for evaluation to issue a Prior Written Notice indicating whether a disability is suspected.
What Missouri Requires
Eligibility requires: age 3–21, a disability as defined by IDEA and the Missouri State Plan, and adverse effect on educational performance requiring special education (Missouri State Plan, Regulation III; 34 CFR 300.8).
Evaluation must use a variety of assessment tools and strategies; no single measure may be the sole criterion for eligibility (34 CFR 300.304(b)).
For SLD, Missouri permits both severe discrepancy (1.5 SD between ability and achievement) and response-to-intervention (RtI) approaches; the discrepancy model is not required (Missouri State Plan, Regulation III).
For YCDD (ages 3–5), eligibility requires performance at or below 1.5 SD in two developmental areas or 2.0 SD in one area of physical, cognitive, communication, social/emotional, or adaptive development (Missouri State Plan, Regulation III).
Districts must conduct child find activities to identify, locate, and evaluate all children with disabilities in the district, including homeless students, wards of the state, and private school students (34 CFR 300.111).
Within 30 days of a parent's referral for evaluation, the district must provide Prior Written Notice (Notice of Action) indicating whether a disability is suspected (Missouri DESE compliance guidance).
Key Timelines
Prior Written Notice must be provided within 30 days of a parent's initial referral for suspected disability (Missouri DESE compliance guidance).
Initial evaluation must be completed within 60 calendar days of parental consent for evaluation (Missouri State Plan, Regulation III; 34 CFR 300.301(c)).
The eligibility determination is made as part of the 60-day evaluation process; once eligibility is confirmed, the IEP must be developed within 30 calendar days of that determination (34 CFR 300.323(c)(1)).
Triennial reevaluation must occur at least every three years (34 CFR 300.303).
