If your child has a diagnosis like asthma, epilepsy, ADHD, diabetes, or a heart condition, you're probably asking a very direct question: does this qualify them for support at school? The honest answer is that it can, but the diagnosis by itself isn't the deciding factor. What matters is whether the condition affects how your child learns and functions in the classroom.
Here's the most useful thing to know first. You don't have to wait for the school to notice a problem. You can ask for a free evaluation, in writing, at any time. That single step starts the whole process.
Let's walk through how eligibility actually works, so you know what you're asking for and what to expect.
What is an IEP, and what does "Other Health Impairment" mean?
An Individualized Education Program (IEP) is a written plan that spells out the special education services and supports a public school will provide for a child who qualifies. It's built by a team that includes you, the parent, and it's a legal document under federal law.
Children qualify for an IEP under one of several disability categories in the Individuals with Disabilities Education Act (IDEA), the federal special education law. For kids with medical conditions, the category that usually applies is called Other Health Impairment, often shortened to OHI.
OHI covers a lot of ground. Under the federal rule, Other Health Impairment means having limited strength, vitality, or alertness because of a chronic or acute health problem. "Chronic" means long-lasting, like diabetes or epilepsy. "Acute" means serious but shorter-term, like a child recovering from a major illness. The rule specifically includes conditions that create a "heightened alertness to environmental stimuli," which is one reason ADHD is often evaluated under OHI.
In plain terms: if a health condition drains your child's energy, focus, or stamina in a way that shows up at school, it may fit under OHI.
Does a diagnosis automatically qualify my child?
No. A diagnosis alone doesn't guarantee an IEP, and it's important to be clear-eyed about that from the start.
IDEA requires two things, not one. First, your child has a qualifying condition. Second, that condition must adversely affect their educational performance. Both parts have to be true.
Think about what that means in real life. Two children can have the same diagnosis of epilepsy. One has well-controlled seizures, keeps up with the class, and needs no special instruction. The other misses school for appointments, struggles to focus after a seizure, and falls behind in reading. The first child may not qualify for an IEP. The second one likely does, because the condition is affecting how they learn.
"Educational performance" is broader than just grades. It can include attention, stamina across a school day, attendance tied to the condition, and the ability to keep pace with classmates. The evaluation is what connects the health condition to the classroom effect.
How do I request an evaluation, and can the school make me wait?
You request an evaluation by putting it in writing. A short letter or email to the school, dated and specific, is enough to start the clock. The Center for Parent Information and Resources offers a model letter for requesting an evaluation that you can adapt to your own child.
In your request, name your child, state that you're asking for a full special education evaluation, and mention the health condition and how it's affecting school. If your doctor has notes or records, you can include them.
Once the school has your written consent for the evaluation, federal law generally gives it 60 days to complete that evaluation, unless your state has set its own timeline. Either way, the request has to be answered. The school can say yes and evaluate, or say no and give you that decision in writing with its reasons, which preserves your right to challenge it.
There's one point that trips up a lot of families, so it's worth stating plainly. A school cannot require your child to go through a "Response to Intervention" or "Multi-Tiered System of Supports" program before it will evaluate. These are known as RTI and MTSS, and they're classroom support programs that many schools use. They can be genuinely helpful. But the U.S. Department of Education's Office of Special Education Programs made clear in a 2011 policy memo (OSEP Memo 11-07) that RTI cannot be used to delay or deny an evaluation once a parent requests one. You're allowed to ask for the evaluation directly.
This isn't about catching the school doing something wrong. It's about knowing what the law already requires so you can hold the process to it.
When can my child start getting services?
Age 3. Under IDEA, special education and related services are available starting at age three, well before kindergarten.
This surprises many parents who assume support only begins once a child is struggling with schoolwork in the early grades. Federal law includes a duty called Child Find, which requires states to identify, locate, and evaluate children with disabilities. That responsibility reaches children as young as three.
So if you have a preschooler with a chronic health condition, you don't have to wait years to ask questions. The door to an evaluation is already open. For a toddler under three, a separate early intervention system applies, and the school district can point you to it.
What educational support looks like for a health condition
Support built around a health condition is practical, not abstract. An IEP for a child with OHI might include scheduled rest breaks, extra time on assignments after a hospital stay, a plan for making up missed work, a health plan the staff follows during the day, or a quiet space to recover after a seizure or a blood sugar check.
The CDC notes that managing chronic health conditions in schools often takes coordination between families, school nurses, and teachers so a child can stay healthy and ready to learn. An IEP is one way that coordination gets written down and made official, so it doesn't depend on any one teacher remembering the details.
The point of the plan is simple. Your child stays in school, keeps learning, and gets the specific accommodations their condition calls for.
FAQs
My child has ADHD. Is that covered under OHI?
Often, yes. ADHD is frequently evaluated under Other Health Impairment because it can affect a child's alertness and focus in the classroom. As with any condition, eligibility depends on whether the ADHD adversely affects your child's educational performance, not on the diagnosis alone. The next step is to request an evaluation in writing so the team can look at how it's showing up at school.
What's the difference between an IEP and a 504 plan?
An IEP provides special education, meaning specially designed instruction, and is governed by IDEA. A 504 plan, which comes from a different federal law, provides accommodations to give a child equal access but doesn't include specialized instruction. A child with a health condition might qualify for one or the other. The evaluation helps determine which fits, so requesting it is still your starting point.
The school suggested we try classroom interventions first. Do I have to agree before an evaluation?
No. Classroom support programs like RTI or MTSS can help, but they can't be used to delay or deny an evaluation you've requested. Per OSEP's 2011 guidance, you have the right to request a full evaluation directly, in writing, and the school must respond. You can accept classroom supports and still ask for the evaluation at the same time.
How long does the evaluation take?
Federal law generally allows 60 days from the date you give written consent, unless your state sets a different timeline. Your written request starts the conversation, and your consent starts that clock. If the school declines to evaluate, it must tell you in writing and explain why, which gives you a clear record to work from.
Next step
Start with the written request. Name your child, name the condition, and ask for a full evaluation. That one letter moves you from wondering to acting.
If you'd rather not walk into the IEP meeting alone, that's exactly where an education advocate helps. Turnout works alongside you: preparing before the meeting, sitting in it with you, and pushing for the support the law already requires for your child. You know your child better than anyone. We know how this system works. Reach out to Turnout when you're ready to take the next step together.
