District Expelled Student With Cognitive Disabilities After Flawed Manifestation Determination

A 16-year-old student with mental retardation and severe speech/language impairment was expelled from Murrieta Valley USD after a September 2008 manifestation determination that failed to consider his cognitive disabilities or the district's failure to implement his IEP. The ALJ found the expulsion improper, ordered the student reinstated, and directed all expulsion records be purged. The student prevailed on both issues in this expedited hearing.

What Happened

A 16-year-old boy with a long history of cognitive impairment and severe receptive and expressive language delays had been receiving special education services since kindergarten. Despite prior assessments consistently showing he functioned in the mild to moderate range of mental retardation — with a cognitive age of roughly five to eight years old — his IEP at the time of enrollment listed only "speech and language impairment" as his eligibility category. In August 2008, he transferred to Vista Murrieta High School within Murrieta Valley USD. Within his first three weeks, a concerning incident occurred in which he entered a girls' restroom and positioned himself to observe female students. He was immediately suspended pending a manifestation determination meeting.

At the September 10, 2008 manifestation determination meeting, the district's school psychologist told the team — including the student's mother — that only the student's speech and language disability could be considered under the law, effectively shutting down any discussion of his cognitive impairment. The associate principal reinforced this by stating that "the disability is not the issue" and that the team needed to protect other students. Not all team members had even reviewed the student's prior evaluations, and there was no discussion of whether the district had actually implemented the student's IEP. The team unanimously found the conduct was not a manifestation of the student's disability, and the school board expelled him for the remainder of the school year. His mother signed the agreement because she believed — based on the school psychologist's misleading instruction — that the law prohibited consideration of anything beyond speech and language.

What the District Did Wrong

Failed to consider all of the student's disabilities. The school psychologist led the manifestation determination team to consider only speech and language impairment, ignoring the student's well-documented cognitive impairment and mental retardation — even when the mother specifically raised it. The district's own prior assessments going back to 1998 had consistently identified the student as mentally retarded.
Did not share relevant records with all team members. Not all members of the manifestation determination team received or reviewed the student's prior evaluations, his behavioral support plan (BSP), or his IEP from San Marcos USD. The associate principal — the highest-ranking team member — had not reviewed these documents.
Misled the parent about her legal rights. The school psychologist incorrectly told the mother that the law only permitted consideration of speech and language disability. This caused her to withdraw her objections and sign the agreement, eliminating her meaningful participation in the process.
Never implemented the student's IEP before the incident. In the three weeks the student attended Vista HS, he received no speech and language therapy (required at 45 minutes per week) and no counseling or psychological services — both of which were mandated by his active IEP and directly relevant to the social-emotional goals the IEP was designed to address. The team never discussed this failure at the manifestation determination meeting.
Did not notify parents of a prior similar incident. A first restroom incident three weeks earlier was never reported to parents, never documented, and no redirection or support was offered to the student — a missed opportunity that may have prevented the second incident.
The associate principal's statement pre-determined the outcome. By stating that "the disability is not the issue," the AP signaled to the entire team that disability analysis was secondary to school safety, further chilling the meaningful consideration the law requires.

What Was Ordered

The student was ordered reinstated at Vista Murrieta High School immediately upon issuance of the decision.
The student's educational records were ordered expunged, with all references to his expulsion from Vista HS purged from his file.

Why This Matters for Parents

Manifestation determinations must consider ALL of your child's disabilities — not just the eligibility category listed on the IEP. If your child has cognitive impairments, a history of mental retardation, or any other documented condition, the team is legally required to consider those conditions, even if the IEP label only says "speech and language." Bring copies of all prior evaluations to the meeting and insist they be reviewed.
If a school official tells you the law limits what the team can consider, ask for that in writing — and consult an advocate or attorney before signing anything. In this case, a parent signed the manifestation agreement because she was incorrectly told the law barred consideration of her son's cognitive deficits. Her signature did not waive her rights, but it complicated the case. Never sign under pressure.
IEP implementation failures are grounds for a finding of manifestation. If the district was not providing required services — like speech therapy or counseling — before the incident occurred, you have a strong argument that the district's own failure contributed to the behavior. Document all missed services carefully.
Request that all team members receive and review your child's complete education file before the meeting. Federal law requires the team to review all relevant information in the student's file, including prior assessments, IEPs, and behavioral support plans. If key members haven't read these documents, the manifestation determination is legally deficient.
Expulsion records can be expunged when a manifestation determination is overturned. If your child was improperly expelled, an ALJ can order that all references to the expulsion be removed from the student's records. This matters for future school placements, college applications, and more — so it is worth pursuing a due process hearing if the manifestation determination was flawed.
