When a Florida school district evaluates a 3- or 4-year-old, the result may be eligibility for exceptional student education (ESE) under a category called "developmentally delayed," sometimes shortened to DD. Some autistic preschoolers are made eligible this way, even when a doctor has diagnosed autism. DD is a useful category for young children, but it has a built-in end date. This guide explains the rule, what it means for your child, and how to plan for the re-evaluation that comes before the category runs out.
What is the developmentally delayed category?
Rule 6A-6.03027, Florida Administrative Code, is titled "Special Programs for Children Three Through Nine Years Old who are Developmentally Delayed." Its definition reads: "A child who is developmentally delayed is three (3) through nine (9) years of age, or through the student's completion of grade 2, whichever occurs first, and is delayed in one (1) or more of the following areas:
(a) Adaptive or self-help development;
(b) Cognitive development;
(c) Communication development;
(d) Social or emotional development; and,
(e) Physical development including fine, or gross, or perceptual motor."
The category exists because it is hard to pin down the exact nature of a disability in a very young child. It lets the district provide services based on documented delays without first deciding on a more specific category.
Who qualifies as developmentally delayed?
Under Rule 6A-6.03027(2), the child must be 3 through 9 years old (unless they have completed grade 2), and the district must document one of the following:
- "A score of two (2) standard deviations (SD) below the mean or a twenty-five (25) percent delay on measures yielding scores in months in at least one (1) area of development"; or
- "A score of 1.5 standard deviations (SD) below the mean or a twenty (20) percent delay on measures yielding scores in months in at least two (2) areas of development"; or
- "For children six (6) or younger and based on information and data, the eligibility staffing committee makes a recommendation that a developmental delay exists and exceptional student education services are needed."
The eligibility committee must also decide about "the effects of the environment, cultural differences, or economic disadvantage." In plain terms, the team has to consider whether something other than a disability, such as limited opportunities to learn a skill or a language difference, explains the scores.
The evaluation uses multiple measures chosen in consultation with you, and parent report is part of it: the rule says parent report can "confirm or modify information obtained and describe behavior in environments that the district may not be able to access" (Rule 6A-6.03027(4)(a)3.). When standardized tests cannot verify a delay, the team may establish it "through observation of atypical functioning," with a written report explaining why (Rule 6A-6.03027(4)(b)).
How is DD different from autism spectrum disorder eligibility?
Florida has a separate ESE category for autism spectrum disorder under Rule 6A-6.03023. That rule requires a specific evaluation, including behavioral observations across settings, a social and developmental history, a psychological evaluation with "at least one (1) standardized instrument specific to autism spectrum disorder," a language evaluation, an adaptive behavior assessment and, when behavioral concerns are present, a functional behavioral assessment. The student must show impairment in social interaction, impairment in language used for social communication, and restricted or repetitive patterns of behavior, interests or activities, across settings, and must need special education.
| Developmentally delayed (6A-6.03027) | Autism spectrum disorder (6A-6.03023) | |
|---|---|---|
| Ages | 3 through 9, ending at completion of grade 2 if earlier | No age limit within ESE |
| What must be shown | A measured delay (2 SD or 25% in one area, or 1.5 SD or 20% in two), or committee recommendation for age 6 or younger | Social interaction, social communication and restricted or repetitive behavior criteria, across settings |
| Autism-specific testing required | No | Yes, at least one standardized autism-specific instrument |
| Continued eligibility | Must be determined before age 10 | Reviewed through regular reevaluations |
The category label does not set your child's services. Services come from the IEP, which must be built around your child's needs. A child eligible under DD can receive speech, behavior supports and other services. Our article on Florida ESE autism eligibility explains the autism category in depth.
What happens before age 10 or after 2nd grade?
Rule 6A-6.03027(6) says: "Continued eligibility for special programs shall be determined before the child is ten (10) years old." Because the definition also ends "through the student's completion of grade 2, whichever occurs first," many children reach the end of DD eligibility at the end of second grade, often around age 8.
Before then, the district needs to decide whether your child is eligible under another category, such as autism spectrum disorder, language impairment or another category that fits, and whether your child still needs special education. That usually means a reevaluation. If no other category applies, ESE services can end. Each district handles the timing in its own procedures, so ask early.
How do reevaluations work?
Rule 6A-6.0331(7) sets the general rules:
- A reevaluation must happen if the district decides your child's needs warrant one, "or if the student's parent or teacher requests a reevaluation."
- Reevaluations may occur "not more than once a year, unless the parent and the school district agree otherwise," and "at least once every three (3) years, unless the parent and the school district agree that a reevaluation is unnecessary."
- The district must get your informed consent before a reevaluation.
If the team decides it needs no new data, it must tell you why and that you have the right to request an assessment (Rule 6A-6.0331(8)).
A planning timeline for families
This is an example, not a legal deadline. Your district's procedures and your child's IEP team set the actual dates.
- At the first IEP: ask which category your child is eligible under and why. If your child has a medical autism diagnosis, share the report and ask whether the district considered the autism category.
- Kindergarten and first grade: at each annual IEP meeting, ask when the district plans to reevaluate and which categories it will consider.
- Early in second grade: if a reevaluation has not been scheduled, request one in writing. That leaves time for testing, an eligibility meeting and an IEP revision before second grade ends.
- Before the eligibility meeting: gather outside reports, such as a private autism evaluation and data from therapists, and ask that they be considered.
If you disagree with the district's evaluation, you can ask for an independent educational evaluation at public expense under Rule 6A-6.03311. If your child has not yet been evaluated, our guide to FDLRS and Child Find and our preschool evaluation letter explain how to start.
How can private ABA help with eligibility decisions?
ABA providers do not decide school eligibility, and BCBAs do not diagnose autism. What a private BCBA can offer is data: skill assessments, behavior records and progress over time that you can share with the IEP team. Hope Center's staff can join IEP meetings where the school allows it, and our clinical director offers diagnostic evaluations with a supervising licensed psychologist. We have no waitlist and offer a free benefits check. Contact us or call 561-337-8865.
