IEP for ADHD in Colorado: Eligibility, Accommodations, and the OHI Category

Getting an IEP for a child with ADHD in Colorado is more complicated than parents expect. ADHD doesn't appear on the list as its own disability category. The school may have suggested a 504 plan instead without explaining why. Or the evaluation came back saying your child "doesn't qualify" despite a confirmed diagnosis. Here is how ADHD actually works in Colorado's IEP system and what you can do about it.

How ADHD Qualifies for an IEP in Colorado

ADHD qualifies for an IEP under the Other Health Impaired (OHI) category, one of the 14 ECEA disability categories. OHI applies to students with chronic or acute health conditions that result in limited strength, vitality, or alertness — including heightened alertness to environmental stimuli — that adversely affects educational performance.

ADHD fits OHI because of the alertness component: the heightened distractibility and the impaired ability to sustain directed attention are neurological characteristics that fall within "limited vitality or alertness." A child whose ADHD causes them to miss significant instructional content because they cannot sustain attention qualifies — provided the evaluation demonstrates the adverse educational impact.

The crucial word is "adverse." The school team must find evidence that ADHD is negatively impacting the child's educational performance. This is where the evaluation data matters. Achievement scores, teacher observations, attendance and completion records, and classroom behavioral data all contribute to establishing adversity.

What Separates an IEP From a 504 for ADHD

Both an IEP and a 504 can address ADHD. The difference is the type of support required:

A 504 plan is sufficient when ADHD impacts access — the student needs accommodations to have the same access to the curriculum as their peers, but they can learn the curriculum through standard instructional methods.

An IEP is necessary when ADHD requires specially designed instruction — instruction that is adapted in content, methodology, or delivery specifically for that child. Examples:

• Executive function skill-building delivered by a special education teacher as a direct service
• Reading or writing instruction using an evidence-based structured program because ADHD co-occurs with a learning disability
• Social skills instruction as a formal related service
• Placement in a smaller class for core academics to allow for more intensive teacher interaction and monitoring

If ADHD is co-occurring with a specific learning disability (dyslexia, dysgraphia, dyscalculia), an IEP is almost certainly the appropriate vehicle because the learning disability requires specialized reading or writing instruction.

The Role of Co-Occurring Conditions

ADHD rarely travels alone. Research consistently shows that 40–60% of individuals with ADHD have at least one co-occurring learning disability. In Colorado evaluations, the school psychologist should be assessing for co-occurring conditions — not just confirming the ADHD diagnosis and determining OHI eligibility, but evaluating whether there are also SLD or other categorical needs.

If your child was evaluated for ADHD only and the school found OHI eligibility but proposed only a 504 plan, consider whether a co-occurring learning disability may have been missed. You can request that the evaluation include a comprehensive assessment of reading, writing, and math processing, not just achievement. If the district declines, you have the right to request an IEE.

Colorado's twice-exceptional framework is also relevant here. A student with ADHD and high cognitive ability may have their executive function deficits masked by their intellectual gifts. The evaluation needs to assess subtest score scatter — if there is a significant discrepancy between fluid reasoning and working memory/processing speed, that is a 2e profile that requires integrated support through an ALP and an IEP.

IEP Accommodations for ADHD in Colorado

The IEP for a student with ADHD under OHI typically includes both accommodations and direct services. Unlike a 504 plan, the IEP specifies direct instruction delivered by special education staff.

Instructional accommodations:

• Extended time on assignments (specified in the IEP, not just informally offered)
• Preferential seating with documented location criteria
• Breaks built into the schedule — specified frequency, duration, and nature (movement break, sensory regulation break)
• Instructions given in written and verbal format with comprehension checks
• Reduced homework load without reducing learning standards

Organizational supports as IEP services:

• Direct instruction in organizational and planning strategies by a special education teacher
• Use of agenda/planner with staff verification
• Assignment notebooks checked by a teacher or case manager
• Digital organizational tools specified in the IEP

Testing accommodations for CMAS: Extended time, separate testing environment, and any assistive technology accommodations must be explicitly listed in the IEP to be valid on CMAS. A student who uses extended time daily but doesn't have it documented in the IEP cannot receive it on the state assessment.

Behavioral supports: If ADHD manifests in behavioral challenges — impulsivity, defiance, emotional dysregulation — the IEP should include a Behavior Intervention Plan (BIP) based on a Functional Behavior Assessment (FBA). The IEP cannot simply list punitive consequences; it must include proactive and replacement behavior strategies.

Service Delivery: What OHI IEPs Actually Look Like

For a student with ADHD under OHI with no co-occurring learning disability, the IEP service delivery might include:

• 30 minutes per week of direct instruction in executive function strategies from a special education teacher (pull-out or push-in to the classroom)
• Check-in/check-out with a case manager daily
• Consult services from the special education team to the general education teachers

For a student with ADHD and co-occurring SLD, the service delivery is heavier:

• 60–90 minutes per day of specialized reading or writing instruction
• Special education support in core academic classes
• Related services if executive function deficits are severe enough to require OT or speech-language support for written expression

When the School Says ADHD Only Needs a 504

Pushback is common. The school says 504 is appropriate, the IEP isn't needed, the child is doing "fine enough." What "fine enough" often means: the child is performing at grade level through enormous effort, is exhausted by the end of the school day, is completing homework with three hours of parental scaffolding every night, and is not actualizing their potential.

Under Colorado's FAPE standard, "appropriate" does not mean "adequate." It means an education reasonably calculated to enable the child to make progress appropriate in light of their circumstances. A student who could be working two grade levels above where they are, but can't access that learning because their ADHD isn't being addressed, is not receiving FAPE.

Document the specific educational impact: what grades would look like without the parental support at home, what happens on days the accommodations slip, how much of the school day is actually inaccessible due to ADHD symptoms. That documentation supports the argument for specially designed instruction.

ADHD IEPs Across Colorado's Administrative Units

The quality and composition of ADHD IEPs varies significantly across Colorado's Administrative Units. A dense urban district like Denver Public Schools typically has more robust special education infrastructure than a rural BOCES member district. In rural areas, the special education teacher may serve dozens of students and be unable to provide more than minimal direct service minutes.

Regardless of staffing constraints, the AU — not the individual school — is legally responsible for delivering FAPE. If the AU claims it cannot staff the services in your child's IEP, document that claim in writing. The AU's legal obligation does not diminish because of its own staffing decisions.

The Colorado IEP & 504 Blueprint covers OHI eligibility in detail, includes sample IEP goals for ADHD, and provides the ECEA-based language you need to request evaluation, challenge an inadequate 504 referral, and hold the AU accountable for delivering specialized instruction.
