District Wins: Bringing a Loaded Gun to School Was Not a Manifestation of Autism

A 13-year-old student with autism was suspended and recommended for expulsion after bringing a loaded handgun to school. The parent challenged the district's manifestation determination, arguing the conduct was caused by the student's autism and the district's failure to provide counseling services. The ALJ upheld the district's determination, finding the student's behavior was too calculated and deliberate to be a manifestation of his disability.

What Happened

Student was a 13-year-old seventh grader with autism spectrum disorder. His IEP placed him in general education 89% of the time and provided specialized academic instruction, group aide support for attention, and monthly group counseling. On March 19, 2025, other students and adults overheard Student say he had a knife in his backpack. When staff searched the backpack, they found a loaded handgun and an empty ammunition magazine. Student initially denied knowing how the weapon got there, but security camera footage contradicted this, and Student then admitted he had brought the gun to school intentionally. He was suspended for five days and later recommended for expulsion for one year.

The district held a manifestation determination review (MDR) on March 31, 2025 — within the required 10-day window. The MDR team, which included Parent, school staff, the school psychologist, the special education director, and attorneys for both sides, determined that Student's conduct was not caused by or substantially related to his autism. Parent disagreed and filed for an expedited due process hearing, arguing that the MDR was flawed and that the district's failure to deliver all of Student's counseling services contributed to the behavior.

What the ALJ Found

The ALJ ruled in favor of the district on both issues. On the question of whether the conduct was a manifestation of Student's autism, the ALJ found the evidence clearly showed that bringing a weapon to school required sustained, deliberate planning — not an impulsive or disability-driven act. Student had searched his home for the weapon, located it in a locked closet inside a locked gun box, found a hidden key, separately located ammunition magazines, concealed the weapon, and carried it to school. This sequence of steps was inconsistent with the kinds of behavioral challenges tied to Student's autism, such as impulsivity, difficulty with social cues, or trouble with self-regulation in the moment.

The parent's expert, a private psychologist who evaluated Student after the incident, testified that the conduct was caused by his autism. The ALJ gave her testimony little weight. Among other problems, the expert could not explain how autism — which typically affects impulse control and social understanding — was responsible for the methodical, multi-step planning Student used to obtain and conceal the weapon. The expert also appeared unaware that Student had initially lied to staff about the gun's origins, which undermined her credibility.

On the question of whether the district's failure to fully deliver counseling services caused the conduct, the ALJ acknowledged there were some missed sessions — Student missed check-ins in August and November due to absences and declined to attend two January sessions when called. However, even accepting that as a failure to implement the IEP, the ALJ found no causal connection between missed counseling minutes and Student's decision to search for, find, and bring a loaded firearm to school.

What Was Ordered

The March 31, 2025 manifestation determination — that Student's conduct was not caused by or substantially related to his disability — was affirmed.
The determination that any lapse in IEP implementation was not a direct cause of Student's conduct was also affirmed.
All relief requested by Student from the expedited hearing was denied.

Why This Matters for Parents

The more deliberate and planned the behavior, the harder it is to win a manifestation determination. Under the law, conduct must be caused by or have a direct and substantial relationship to the disability. Behaviors that require multi-step planning — like searching for a weapon over time and concealing it — are much harder to link to disabilities like autism than impulsive, in-the-moment reactions.
A private evaluation done after the incident may carry less weight. The parent's expert evaluated Student almost three months after the incident and was not present at the MDR. The ALJ found gaps in her knowledge of key facts. If you plan to challenge an MDR, getting an expert involved early — and making sure they review all investigation materials — strengthens your case.
Missed IEP services alone are not enough to win on IEP implementation. The parent argued that missed counseling sessions contributed to the behavior. But courts and ALJs look for a direct causal link between the missed service and the specific conduct at issue. If Student missed sessions due to his own absences or refusals, that further weakens the argument that the district failed him.
Parents have the burden of proof in expedited discipline hearings. Unlike some special education disputes, the parent who challenges a manifestation determination must prove their case — the district does not have to prove the behavior was not a manifestation. Come prepared with strong evidence, including records, expert opinions, and documentation of how the student's specific disability characteristics connect to the specific behavior in question.
