District Wins Manifestation Determination Appeal: Student's Fighting Not Linked to ADHD

A parent challenged Tehachapi Unified School District's determination that their 17-year-old son's fighting incidents were not caused by his ADHD-based disability. The ALJ found that while the district used outdated legal standards during its review, the error was harmless because the evidence still showed no direct connection between the student's disability and the violent conduct. The district was allowed to proceed with expulsion.

What Happened

Student was a 17-year-old 12th grader at Tehachapi High School who received special education services under the category of Other Health Impairment (OHI), primarily based on a diagnosis of ADHD. He also had a history of learning difficulties, high anxiety, and — during middle school — multiple altercations that had led to placement in home instruction. By high school, however, Student had made significant progress: he was a varsity basketball player, had participated in a work-experience program without incident, and his teachers described him as focused, cooperative, and capable of planning ahead.

On October 17, 2005, Student physically struck two classmates at school after learning the day before that a peer may have sexually assaulted his girlfriend. He confronted the first student, who denied the allegation, and a physical altercation followed. A second student was also punched when he got involved. One student sustained a concussion; the other had a broken nose. Student was suspended for five days and faced possible expulsion. Under federal law, before a district can expel a student with a disability, it must hold a "manifestation determination review" — a meeting to decide whether the behavior was caused by, or directly related to, the student's disability. The district held that meeting on October 31, 2005, and concluded the conduct was not a manifestation of Student's disability. Parent appealed that decision by filing for a due process hearing.

What the ALJ Found

The ALJ found that the district made a procedural error during its manifestation determination review: it used the standards from the old version of federal special education law (IDEA) rather than the updated standards that took effect in July 2005. Under the old law, the team asked whether Student's disability impaired his ability to understand the consequences of his behavior or control his actions. Under the new law, the correct questions are: (1) Was the conduct a direct result of the district's failure to implement Student's IEP? and (2) Was the conduct caused by, or did it have a direct and substantial relationship to, Student's disability?

Despite this procedural mistake, the ALJ ruled that the error was harmless — meaning it didn't change the outcome. The evidence overwhelmingly showed that Student's ADHD and OHI disability did not directly cause his behavior on October 17. Student had a clear, emotionally understandable reason for his actions (anger over the alleged assault of his girlfriend), not a disability-driven loss of control. His teachers reported no ongoing behavioral problems. He had demonstrated consistent self-regulation in school, at work, and on the basketball court. While the student's anxiety and ADHD may have played a distant role, the ALJ found this was at most an attenuated connection — not the direct and substantial relationship the law requires to shield a student from discipline.

The ALJ also noted that the district's IEPs had been implemented as written, so there was no IEP failure that could have triggered a manifestation finding on that basis. The ALJ encouraged the district to still consider conducting a functional behavioral assessment (FBA) and updating Student's IEP as appropriate, to help prevent future incidents — even though the expulsion could legally proceed.

What Was Ordered

Student's request for relief from the district's manifestation determination was denied.
The district was permitted to proceed with expulsion proceedings.
The district was reminded that it may consider unique circumstances on a case-by-case basis when deciding whether to actually carry out a change in placement.

Why This Matters for Parents

The law changed in 2005, and districts must use the right standards. The manifestation determination rules under IDEA 2004 are different from the old law. If your district uses outdated criteria in its review — asking only whether your child "understood consequences" or "could control behavior" — that is a legal error. However, as this case shows, a procedural mistake alone may not be enough to win if the underlying evidence doesn't support a disability connection.
A disability must directly cause the behavior, not just be present. Having a diagnosis of ADHD (or any other disability) does not automatically mean every behavioral incident is a manifestation of that disability. The law requires a direct and substantial relationship between the disability and the specific conduct. A student who generally functions well and has a situational, emotionally understandable reason for misbehaving faces an uphill battle in a manifestation determination.
Your child's track record in school matters enormously. The fact that Student's teachers, coaches, and work supervisors all described him as focused, responsible, and in control worked strongly against Parent's case. Document any ongoing behavioral struggles — not just the single incident — because a pattern of disability-related behavioral difficulty is far more likely to support a manifestation finding than an isolated event.
Even if the district wins, it still has obligations. The ALJ made clear that even when a behavior is not a manifestation of disability, the district should consider conducting a functional behavioral assessment and updating the IEP to address the behavior and prevent recurrence. Parents can and should push for these supports during any expulsion process.
