District Wins: Firecracker Incident Not a Manifestation of Student's ADHD

A 15-year-old student with ADHD was suspended and recommended for expulsion after possessing and attempting to light firecrackers during lunch at his Riverside high school. His parent challenged the district's manifestation determination review, arguing that his impulsivity caused the conduct and that IEP implementation failures contributed to it. The ALJ ruled in favor of Riverside, finding the student's actions were deliberate rather than impulsive and that the district had substantially implemented his IEP.

What Happened

A 15-year-old student, eligible for special education under the category of "other health impairment" due to ADHD, had a long history of behavioral incidents at Riverside Unified — primarily in-class disruptions, defiance, profanity, and tardiness. He had an IEP with behavioral goals and a behavior support plan designed to address his poor impulse control. On February 28, 2014, during his lunch period, a peer handed him a firecracker and pressured him to light it. The student initially declined, saying he would wait until after school to avoid getting caught. He then returned to the same group of peers 10–15 minutes later, was goaded by peers into trying to light a second firecracker embedded in an apple, walked down a pathway away from the group, and attempted to light it. The firecracker did not ignite due to rain. An unlit firecracker was later found in his backpack. Riverside suspended him for five days and recommended expulsion.

The student's parent challenged the district's manifestation determination review (MDR), arguing that the student's ADHD-related impulsivity caused the conduct and that Riverside's failure to fully implement his IEP and behavior support plan contributed to the incident. The parent's expert, a clinical psychologist who had originally assessed the student in 2009 and re-assessed him in March 2014, opined that lighting the firecracker was an impulsive act driven by peer pressure and ADHD. However, the ALJ found the expert's opinion undermined by his limited knowledge of the full sequence of events and his lack of direct contact with the student since the family moved into Riverside's boundaries years earlier.

What the ALJ Found

The ALJ ruled entirely in favor of Riverside on both issues presented at the expedited hearing.

Student's conduct was not a manifestation of his ADHD. The ALJ found that the student's actions were deliberate, not impulsive. He knew firecrackers were present on campus for two weeks and never reported it. When first handed a firecracker, he consciously decided to wait until after school to light it so he would not get caught — a calculated choice that demonstrated awareness of consequences. He then voluntarily returned to the same peer group. Even assuming the second firecracker incident could be viewed separately, the student's possession of the first firecracker alone was sufficient grounds for expulsion under the Education Code, and that act was clearly not impulsive.
Riverside did not materially fail to implement the student's IEP. The ALJ found that the special education teacher distributed IEP-at-a-Glance documents to all general education teachers, communicated regularly about the IEP, and implemented the Skill Streaming curriculum in her class to address the student's impulse-control goal. Although there were minor implementation gaps — the escort to first and sixth periods had been replaced with visual monitoring, and progress reports were not consistently sent to the parent — the student failed to show any causal connection between those gaps and the firecracker incident. The IEP did not require monitoring during lunch, which is when the incident occurred.
Procedural challenges to the MDR were rejected. The ALJ found that the mother attended and fully participated in the MDR despite receiving only verbal (not written) notice beforehand. She never contacted the family's psychologist to ask him to attend by phone, and she could not identify who else she wanted to bring. The MDR team reviewed the student's assessment, IEP, discipline history, teacher observations, and the student's written statement. No evidence showed that any missing information would have changed the outcome.

What Was Ordered

The student's request to overturn Riverside's manifestation determination was denied.
The student's request to be returned to his original placement at his home high school was denied.
Riverside was permitted to proceed with expulsion proceedings as it would for any student without an IEP.

Why This Matters for Parents

The bar for "impulsivity" as a manifestation is high — context matters enormously. An ADHD diagnosis and a history of impulsive behavior are not enough on their own. The ALJ looked carefully at the full sequence of events: if your child made any deliberate decision (like waiting to act to avoid getting caught), that weighs heavily against a finding that the conduct was impulsive. Document and present the complete factual picture at the MDR before the district locks in its narrative.
Your expert's opinion is only as strong as the facts they know. The parent's psychologist had not spoken directly with the student about the incident, had not read the student's written statement, and was working from a secondhand account. When confronted with the fuller facts at hearing, he had to concede ground. Before retaining an expert for an MDR challenge, make sure they review all available records and speak directly with your child.
Get your expert to the MDR, not just to the hearing. The psychologist in this case could have participated by phone at the MDR but was never contacted by the parent. Having expert input at the MDR itself — before the district's determination is made — is far more powerful than presenting that expert only at a due process hearing months later.
Minor IEP implementation failures won't win an MDR challenge without a causal link. Even where Riverside fell short (inconsistent escorts, missing progress reports), the student could not show that those failures caused him to possess or light firecrackers at lunch. To succeed on an IEP-implementation argument in an MDR, parents must be prepared to demonstrate how the missing service or support directly contributed to the specific conduct at issue.
Raise procedural objections to the MDR process clearly and early. The student tried to raise procedural complaints (short notice, missing documents, interruptions) but had framed his due process complaint around substantive issues. The ALJ found those procedural issues were not properly before the hearing. If you believe the MDR process was flawed — notice was inadequate, key people were excluded, relevant records were missing — state those objections explicitly in your due process complaint and document them in writing at the time of the meeting.
