Other Health Impairment under IDEA is the special education category for children whose chronic or acute health conditions drain their strength, stamina, or ability to focus enough that regular classroom instruction no longer works. To qualify, a medical diagnosis alone isn’t enough. A school team has to find that the condition measurably harms your child’s educational performance and that your child needs specially designed instruction to make progress.
What OHI Covers
The Individuals with Disabilities Education Act organizes disabilities into thirteen categories, and a child must fit within at least one category and need special education to qualify.1Individuals with Disabilities Education Act. About IDEA OHI is the category built for medical conditions that affect the body or a child’s alertness, rather than fitting neatly under specific learning disability, emotional disturbance, or another label.
The regulatory definition at 34 CFR § 300.8(c)(9) describes OHI as having limited strength, vitality, or alertness, including a heightened sensitivity to environmental stimuli that reduces a child’s ability to focus in the classroom, when that limitation is caused by a chronic or acute health problem and hurts educational performance.2eCFR. 34 CFR 300.8 – Child With a Disability That “heightened alertness to environmental stimuli” language is why attention deficit disorder and ADHD live in this category. A child hyper-aware of every sound and movement has plenty of alertness, just aimed at everything except the lesson.
Conditions That Can Qualify
The regulation names asthma, ADD and ADHD, diabetes, epilepsy, heart conditions, hemophilia, lead poisoning, leukemia, nephritis, rheumatic fever, sickle cell anemia, and Tourette syndrome as examples.2eCFR. 34 CFR 300.8 – Child With a Disability The word “such as” in front of that list matters. The list is illustrative, not exhaustive. A child with a rare autoimmune disorder, a genetic condition not mentioned by name, or another chronic illness can still qualify if the condition meets the definition.
The U.S. Department of Education has confirmed that long COVID and multisystem inflammatory syndrome in children (MIS-C) can qualify a child under OHI. Persistent fatigue, difficulty concentrating, and reduced stamina fit within the “limited strength, vitality, or alertness” language of the regulation.3U.S. Department of Education. Long COVID Under Section 504 and the IDEA The label on the diagnosis matters less than the functional impact.
The Three-Part Eligibility Test
A diagnosis is the starting point, not the finish line. Your child qualifies for special education under OHI only when all three of these are true:
- The health condition limits your child’s strength, vitality, or alertness in the educational setting. For students with ADHD, this usually shows up as heightened responsiveness to distractions pulling attention away from instruction.
- The condition is a medically recognized chronic or acute health problem. Chronic conditions are ongoing, like diabetes, epilepsy, or sickle cell anemia. Acute conditions may appear suddenly and be shorter-lived but still severe enough to impair functioning while they last.
- The condition adversely affects your child’s educational performance.
All three prongs must be met.4Individuals with Disabilities Education Act. Sec. 300.8 Child With a Disability A child with well-managed asthma who performs fine won’t meet the third prong even though asthma is explicitly named in the regulation. A child whose unlisted condition causes crushing fatigue and plummeting grades can meet all three.
“Educational Performance” Is Broader Than Grades
This is where school teams often go wrong. Some districts read “adversely affects educational performance” to mean “the child is failing.” But IDEA itself defines an IEP as including both academic achievement and functional performance goals.5Individuals with Disabilities Education Act. Section 1414 – Evaluations, Eligibility Determinations, Individualized Education Programs, and Educational Placements Functional performance covers social interaction with peers, behavior regulation, consistent attendance, and completing daily routines. A child pulling straight A’s can still qualify if the health condition causes severe behavioral difficulties, chronic absenteeism, social isolation, or emotional distress that a parent or teacher has to constantly compensate for.
Medication side effects count too. A student whose seizure medication causes drowsiness, or whose ADHD medication wears off mid-afternoon leaving them unable to function in later classes, is experiencing a limitation on alertness caused by the condition and its treatment. Make sure the evaluation team looks at these effects, not just the report card.
Documentation to Build Your Case
Eligibility runs on evidence from two sides, medical and educational, and both need to be strong before the team meets.
Medical Documentation
You need a formal diagnosis from a licensed healthcare provider identifying the condition and describing how it affects your child’s daily functioning. Most districts have their own medical verification forms that ask the physician to address stamina, alertness, and limitations on school activities. Contact the special education department or school counselor to get those forms before your child’s appointment. The physician’s statement should cover how often symptoms occur, whether they are predictable or episodic, and what medications your child takes along with any side effects like drowsiness, appetite changes, or agitation.
Educational Evidence
The district gathers its own data to measure whether the condition is actually hurting school performance. Expect the team to review classroom assessments, standardized test scores, work samples, and attendance records. Teacher observations carry serious weight. A teacher documenting that a child stares blankly for ten-minute stretches, needs frequent nurse visits, or melts down every afternoon is providing exactly the kind of functional evidence that links the medical condition to the classroom. If your child’s grades are acceptable but the effort behind them is unsustainable, gather evidence of that. Emails with teachers, notes about homework taking three times longer than it should, and records of informal accommodations already in place all help.
How the Evaluation Works
Once you give written consent, federal regulations give the district 60 days to complete the evaluation, unless your state has set a different timeline.6eCFR. 34 CFR 300.301 – Initial Evaluations The evaluation isn’t a single test. It’s a process of collecting and reviewing the medical documentation, academic records, teacher observations, and any additional assessments the team decides are needed.
A team then meets to review everything. This typically includes you, a general education teacher, a special education teacher or provider, someone who can interpret evaluation results, and a district representative. The team walks through whether the evidence satisfies all three prongs. If your child qualifies, the district has 30 days to hold a meeting and develop an Individualized Education Program with specific goals, services, and accommodations.7eCFR. 34 CFR 300.323 – When IEPs Must Be in Effect Services must begin as soon as possible after the IEP is finalized.
Whatever the outcome, the district must give you a Prior Written Notice explaining the decision, what evidence the team relied on, what options were considered, and what was rejected.8eCFR. 34 CFR 300.503 – Prior Notice by the Public Agency; Content of Notice Read it carefully. If your child is found ineligible, that notice is the starting point for deciding whether to challenge the decision.
You have a legal right to participate in every meeting about identification, evaluation, and placement.9Individuals with Disabilities Education Act. Sec. 300.501 – Opportunity to Examine Records; Parent Participation in Meetings If you can’t attend in person, the school must offer alternatives like phone or video conferencing.
If the School Says No
An ineligibility decision isn’t the end of the road. IDEA gives you several ways to push back.
Independent Educational Evaluation
If you disagree with the district’s evaluation, you can request an Independent Educational Evaluation at public expense.10eCFR. 34 CFR 300.502 – Independent Educational Evaluation The district then has two choices: pay for an outside evaluator or file a due process complaint to prove its own evaluation was appropriate. It cannot simply refuse, and it cannot require you to explain why you disagree. You get one IEE at public expense each time the district conducts an evaluation you disagree with, and the independent evaluator must meet the same qualifications the district requires of its own. Even if you end up paying for a private evaluation yourself, the school team must consider the results.
Mediation
Mediation is voluntary. You and the school sit down with a trained, impartial mediator, and the state pays. The mediator cannot be a district employee involved in your child’s case.11eCFR. 34 CFR 300.506 – Mediation Mediation cannot be used to delay or deny your right to a due process hearing. If it produces an agreement, both sides sign a legally binding document enforceable in court.
Due Process Complaint
If mediation doesn’t work, or you prefer a formal proceeding, you can file a due process complaint. Within 15 days, the school schedules a resolution meeting to try to settle. Both sides can agree in writing to skip that meeting or use mediation instead. If the dispute isn’t resolved within 30 days, the case moves to a hearing where an impartial officer reviews the evidence and issues a binding decision.12Individuals with Disabilities Education Act. Sec. 300.510 – Resolution Process Parents who reach this stage often benefit from consulting a special education advocate or attorney, especially if the district has legal counsel at the table.
When Section 504 Fits Better
Not every child with a health condition needs an IEP. Some children do fine in general education but need specific accommodations: extra time on tests, permission to visit the nurse for medication, a modified physical education class, or preferential seating. For those students, a Section 504 plan may be the better fit.
Section 504 of the Rehabilitation Act uses a broader definition of disability than IDEA. Where IDEA requires “specially designed instruction,” Section 504 covers any student with a physical or mental impairment that substantially limits a major life activity such as learning, breathing, or concentrating. The Department of Education has specifically noted that students with long COVID or conditions like asthma and diabetes may qualify for Section 504 protections even if they don’t meet IDEA’s stricter criteria.3U.S. Department of Education. Long COVID Under Section 504 and the IDEA
If your child is evaluated for OHI and found ineligible because the team decides the condition doesn’t require specially designed instruction, ask the school about a Section 504 evaluation. Many students with health impairments get meaningful support through 504 plans, including flexible attendance policies, modified assignments, access to a health aide, or permission to carry and self-administer medication.
Eligibility Isn’t Permanent
The school must re-evaluate your child at least once every three years to confirm continued eligibility and appropriate services.13eCFR. 34 CFR 300.303 – Reevaluations A re-evaluation can happen sooner if you, a teacher, or the school requests one, which matters when a child’s condition worsens or improves significantly. Re-evaluations can’t happen more than once a year unless you and the school agree, and you can also agree to waive the three-year re-evaluation if the current data still reflects your child’s needs. Keep an eye on this timeline. A child whose condition changes shouldn’t be locked into a plan built around who they were three years ago.
