Colorado School Removed Her Disability Support Because Her Scores Improved

Last updated: July 10, 2026

Every parent of a child with dyslexia or ADHD asks some version of the same question once accommodations start working: what happens if my child gets better? In too many school districts, the answer is that the supports go away. A Colorado family found out exactly how that works in April 2026, and the lawsuit they filed in response carries legal information every parent with a child on a 504 plan or IEP needs to have before their next re-evaluation.

A fifth grader at Appleton Elementary in Grand Junction has documented dyslexia and ADHD and, by her district’s own account, exceptional cognitive abilities. She had a Section 504 accommodation plan. She improved academically. Mesa County Valley School District 51 responded by ending the plan, citing her test scores as proof the disability no longer substantially limited her in the classroom. Her mother is now suing the district in federal court. The legal argument at the center of the case is straightforward, and it is one the federal government resolved in 2008.

TL;DR

A Colorado parent is suing Mesa County Valley School District 51 after the district ended her fifth grader’s Section 504 plan in April 2026.
The child has documented dyslexia and ADHD; the district terminated the plan because her statewide test scores no longer fell below the 12th percentile.
The lawsuit alleges the district applied an incorrect legal standard: Section 504 requires evaluating whether a disability substantially limits major life activities, not whether a child performs above a percentile cutoff.
The Americans with Disabilities Act Amendments Act of 2008 explicitly prohibits using mitigating measures, including the accommodations that helped a child’s scores improve, in disability eligibility determinations.
Parents of children on any 504 plan or IEP have the right to challenge a district’s eligibility determination and to demand evaluation of the disability without accommodations in place.

A Colorado lawsuit over a revoked 504 plan carries legal information every parent of a child with a learning difference needs before their next re-evaluation meeting.

Common questions

Can a school remove my child’s 504 plan if their grades improve?

No. Academic improvement does not disqualify a student from Section 504 protections. The Americans with Disabilities Act Amendments Act of 2008 (ADAAA) requires disability eligibility to be evaluated without regard to mitigating measures, including the accommodations that may have contributed to improved grades or scores. A district that cites improved test results to eliminate a 504 plan is applying the wrong legal standard if those results came from accommodations being in place. If your child’s school moves to terminate a 504 plan, you have the right to attend the re-evaluation meeting, submit documentation, and challenge the decision. A screener is a starting point, not a diagnosis; for formal accommodations through an IEP or 504 plan, or if a vision, hearing, or medical cause is possible, a professional evaluation is the route to those supports.

What does “substantially limits a major life activity” actually mean under Section 504?

Section 504 of the Rehabilitation Act protects students whose disabilities substantially limit one or more major life activities. Those activities include reading, concentrating, processing information, communicating, and learning, among others. Critically, the evaluation of whether a disability substantially limits these activities must be conducted without considering mitigating measures, including medications and accommodations. A student who reads at grade level because of extended time and a quiet environment still faces a substantial limitation in reading as that activity would exist without those supports. The standard is not whether a student performs above a percentile cutoff on a statewide test.

My child’s school says they no longer qualify for a 504 plan. What are my options?

You have the right to request a copy of the evaluation report and ask the district to explain specifically which legal standard it used and how it evaluated the disability without accommodations in place, as required by the ADAAA. You have the right to request an independent educational evaluation at the district’s expense in some circumstances, and to formally challenge the eligibility determination through the district’s dispute resolution process. If the district used a test score percentile cutoff rather than a full major life activities analysis without mitigating measures, that is grounds for a formal challenge. Contact a special education advocate or attorney if the district does not respond to a direct request for the legal basis of the determination.

My child has dyslexia or ADHD but their test scores are at grade level. Can they still qualify for a 504 plan?

Yes. Grade-level test performance does not disqualify a student from Section 504 eligibility. What matters is whether the underlying disability substantially limits a major life activity when evaluated without mitigating measures. A child with dyslexia who reads at grade level because they work significantly harder than peers, use adaptive strategies, or receive tutoring is still substantially limited in reading as the ADAAA defines it. A screener is a useful starting point for understanding your child’s processing profile, but it is not a diagnosis. If your child needs formal accommodations through an IEP or 504 plan, or if a vision, hearing, or medical cause is possible, a professional evaluation is the route to those supports.

A Colorado district ended a child’s 504 plan after she improved

In April 2026, Mesa County Valley School District 51 (D51) in Grand Junction, Colorado, terminated the Section 504 plan for a fifth grader at Appleton Elementary School. The student has documented dyslexia and ADHD alongside what the court complaint describes as exceptional cognitive abilities. The district’s stated justification: her disabilities “do not substantially limit her ‘in the classroom,’” and she had not scored below the 12th percentile on any generalized statewide standardized assessment.

The student’s parent filed suit in federal court, alleging the district relied on “an incorrect legal standard, improper reliance on mitigating measures, flawed and incomplete evaluation methods, and a process that failed to meaningfully consider relevant evidence.” The family is asking the court to restore the 504 plan and award compensatory damages. The complaint states that “Section 504 requires consideration of whether a student’s impairments substantially limit major life activities, not whether the student falls below a particular percentile cutoff or performs below grade level.”

What the coverage gets wrong

Coverage of this case focuses on the lawsuit as an isolated dispute. What goes unreported: districts across the country routinely use test score improvement as a proxy for disability elimination, which the Americans with Disabilities Act Amendments Act of 2008 explicitly prohibits. The ADAAA requires disability eligibility to be evaluated without regard to mitigating measures, including the very accommodations that generated the improved scores. When a 504 plan works and a child’s numbers go up, the legally correct response is to confirm the plan is doing its job. Using those numbers to end the plan inverts the legal standard. This gap between how many districts operate and what federal law requires affects every family whose child has responded well to support, and it is substantially underreported.

Federal law since 2008 says test scores with accommodations cannot end a 504 plan

The district’s logic has a specific legal problem: the supports that helped this child improve are the mitigating measures the law says cannot be used to eliminate eligibility. The Americans with Disabilities Act Amendments Act of 2008 (ADAAA) is explicit on this point. When determining whether a disability “substantially limits” a major life activity, schools are legally required to evaluate the child’s impairment without regard to mitigating measures. Mitigating measures include medications, adaptive strategies, and the accommodations themselves. A student with dyslexia who achieves at grade level because her 504 plan provides extended time and a quiet testing environment still has dyslexia. Using those accommodations as evidence that disability no longer limits her is exactly what the ADAAA prohibits.

The district’s 12th percentile threshold is also legally off-target. Section 504 of the Rehabilitation Act protects students whose disabilities substantially limit major life activities: reading, concentrating, processing information, communicating. A statewide test score is a measurement of output with accommodations in place. It is not an evaluation of the underlying impairment without them. The U.S. Department of Education’s Office for Civil Rights has stated this distinction repeatedly in guidance following the 2008 amendments. Academic success, the OCR confirms, does not disqualify a student from 504 protections. Dyslexia is a persistent difference in how the brain processes language, not a condition that resolves when a child learns to manage it with tools in place.

The pattern this creates is real and predictable: a 504 plan works, scores rise, and a district concludes the plan is no longer necessary. The legally correct conclusion is the opposite. The plan is working. Improvement caused by a mitigating measure cannot be cited as grounds to remove the measure. Parents need to understand this before their next re-evaluation, not during it.

Key Takeaways:

Improving with accommodations does not make accommodations unnecessary: When a 504 plan works and scores rise, those scores reflect the support working, not the disappearance of the disability. Federal law requires the disability to be evaluated without accommodations in place.

ADAAA 2008 bars using mitigating measures to deny eligibility: Schools are legally prohibited from counting accommodations, medications, or adaptive strategies when determining whether a disability substantially limits a major life activity. A district that cites 504-plan-supported test scores to end a 504 plan violates this federal prohibition.

A test score percentile cutoff is not the Section 504 eligibility standard: Section 504 asks whether a disability substantially limits a major life activity, evaluated without the accommodations in place. Parents have the right to challenge any eligibility determination that relies on a percentile threshold instead.

What this means at your child’s next 504 or IEP meeting

If your child is on a 504 plan or IEP and has been doing better, that is the goal. It does not give a district legal grounds to remove the support. Before any re-evaluation of eligibility, push for answers to three specific questions.

First: is the district evaluating your child’s disability as it exists without the accommodations in place? Under the ADAAA, that is the required approach. A child who reads at grade level with extended time and a low-distraction room available still has a processing barrier. Evaluating her with those tools already in place and citing the output as proof she does not need them inverts the legal standard.

Second: is the district looking at all major life activities, or only in-classroom test performance? Section 504 covers reading, concentrating, processing information, and other activities beyond what shows up on a state test. A child who works twice as hard to achieve the same result as classmates without accommodations is substantially limited, even when the numbers look fine on paper. Third, if your child’s school moves to terminate a 504 or reduce an IEP, you have the right to request an independent educational evaluation, to attend the re-evaluation meeting with your own documentation, and to formally challenge the eligibility determination. You do not have to accept a test-score percentile as the standard. Federal law has been clear about this since 2008. The Colorado case is now a reminder that not every district has read it.

Parents of children who learn differently are not passive observers in this system. Nobody knows your child the way you do, and when a district moves to remove a support that is working, you have both the standing and the right to push back with the actual legal standard. The problem in Colorado is not one principal in one district. It is a measurement approach that defines disability by output with tools in place, then uses that output to end the tools that produced it. Federal law has prohibited this since 2008. The question is whether parents know what it says before they need it. Understanding your child’s actual processing profile across reading, auditory, visual, and attention systems gives you the foundation for those conversations.
