Student Reinstated After District Ignored Bipolar Diagnosis at Manifestation Determination

A 17-year-old student with hearing loss, ADHD, and bipolar disorder was suspended pending expulsion after punching an assistant principal. The district held a manifestation determination (MD) review but only considered his hearing impairment and failed to address his bipolar diagnosis, hospitalization, and history of emotional dysregulation. The ALJ found the MD procedurally invalid and ordered the student immediately reinstated, while also ruling that the punch itself was not an impulsive act tied to his ADHD.

What Happened

A 17-year-old student at Roseville High School had a long history of academic and behavioral struggles. He qualified for special education primarily under the category of hard of hearing, and had previously held a secondary eligibility of "other health impaired" due to ADHD — a category the district dropped at his November 2012 triennial IEP meeting. His treating therapist had diagnosed him with ADHD combined type since 2006 and impulse control disorder since 2010. On May 2, 2013, following a heated confrontation with his girlfriend over text messages, the student defied multiple staff directives over roughly 20 minutes and ultimately punched the assistant principal who was blocking a doorway. He was suspended pending expulsion and, later that same day, placed on a psychiatric hold after telling a friend he intended to overdose on medication. He was hospitalized for five days and discharged with a new diagnosis of bipolar disorder with psychotic features.

The district convened a manifestation determination (MD) review on May 9, 2013 — just two days after the student's discharge from the psychiatric hospital. The school psychologist who led the meeting told the parent the team's job was only to decide whether the student's qualifying disability (hearing loss) caused the conduct. When the parent raised ADHD, the team discussed it briefly but made no formal finding. When she presented a letter from the student's treating psychiatrist at Heritage Oaks describing his bipolar disorder, the team did not meaningfully address it. The district concluded the conduct was not a manifestation of any disability and placed the student on home instruction pending expulsion. The parent appealed.

What the District Did Wrong

The ALJ found the MD procedurally invalid on Issue Two, while ruling in the district's favor on Issue One (whether the conduct was a manifestation of ADHD/impulse control disorder).

1. The team was told — incorrectly — to only consider the qualifying disability listed in the IEP. The special services coordinator testified that the MD review team is only required to consider the disability listed on the student's current IEP (hearing loss). This is legally wrong. The law requires the team to consider all known or suspected disabilities. The student's records were full of references to ADHD, and the team was required to formally answer whether his conduct was a manifestation of that condition as well.

2. The district ignored the bipolar diagnosis and psychiatric hospitalization. The student's school psychologist personally visited him at the hospital on May 7, 2013, and learned from the parent about the new bipolar diagnosis and the prescribed medication. The parent also submitted a letter from the hospital psychiatrist at the MD meeting. Despite this, the MD team did not discuss bipolar disorder, the student's suicidal ideation, his 5150 psychiatric hold, or his hospitalization. The ALJ rejected the district's argument that only information known at the moment of the disciplinary conduct was "relevant" — an MD review looks backward in time, and all information available by the day of the meeting must be considered.

3. The team reviewed only a brief, detail-free summary of the incident. Rather than reviewing witness statements or inviting the student to describe what happened, the team lead simply read a short summary of the event. No witness statements were reviewed. This left the team without an adequate understanding of the student's emotional state at the time — information directly relevant to a manifestation inquiry.

4. The team did not address the student's history of emotional dysregulation. In the months before the incident, school staff had documented a pattern of escalating emotional and behavioral crisis: suicidal ideation shared with a coach's family member in August 2012, a three-week period of deteriorating behavior, truancy, and rage in April 2013, and the student running away from home. None of this was discussed at the MD meeting, even though it was directly relevant to whether the student had an unaddressed mental health condition that may have contributed to his conduct.

On Issue One (ADHD/impulse control), the district prevailed. The ALJ found the student's conduct was not impulsive. The event lasted over 20 minutes, involved multiple warnings from several trusted adults including his coach and a friend, and showed purposeful evasion and intent. The ALJ found that the student made a series of deliberate decisions to pursue his girlfriend and ultimately struck the assistant principal to gain entry — conduct reflecting poor judgment and intense emotion, but not the kind of spontaneous, unplanned act characteristic of impulsivity.

What Was Ordered

The student's suspension was set aside.
The student was immediately reinstated at Roseville High School, with full participation in football and other extracurricular activities as he had before his suspension.
If the district wished to proceed with expulsion, it was required to convene a new MD review team meeting within 10 school days of the decision — this time properly considering whether the student's conduct was a manifestation of his bipolar disorder and related emotional dysregulation.

Why This Matters for Parents

A manifestation determination must cover ALL known disabilities — not just the one listed in the current IEP. If your child has a diagnosis of ADHD, anxiety, bipolar disorder, or any other condition that the school is aware of — even if it is not listed as a special education eligibility category — the MD team is legally required to consider whether the disciplinary conduct was related to that condition. If a school official tells you the team only needs to look at the "qualifying" disability on the IEP, that is incorrect.
Bring documentation to the MD meeting and make sure it enters the record. The parent in this case brought a letter from the hospital psychiatrist to the meeting. That letter was critical in establishing what the district knew and when. Bring any letters, discharge summaries, diagnoses, or treatment records from outside providers. Ask that they be included in your child's file and referenced in the meeting notes.
Information that emerges after the incident but before the MD meeting must be considered. The district argued it could only look at what was known the moment the punch was thrown. The ALJ rejected this. If your child is hospitalized, placed on a psychiatric hold, or receives a new diagnosis in the days between the incident and the MD meeting, that information is relevant and the team must address it.
A history of emotional or behavioral crisis at school is relevant to a manifestation determination. Prior incidents of suicidal ideation, emotional meltdowns, or escalating behavior can be important evidence that a student has an underlying disability affecting their behavior. If the school has documented these events, ask that they be reviewed at the MD meeting.
Even if the district wins on the "was it impulsive?" question, you can still win on procedure. This case shows that a district can prevail on the substantive question of whether conduct was a manifestation, yet still lose because the process was flawed. A procedurally invalid MD can be set aside and the student reinstated — giving the family more time and a second chance at a proper review. If you believe the team failed to consider relevant information or excluded key disabilities from its analysis, that procedural argument is worth raising.
