Devon's Knife: Manifestation Determination and the Weapon Exception

This is a disciplinary change of placement, so the procedural clock starts now.

1. Manifestation determination review within 10 school days of the decision to change placement. The relevant IEP team - including the parents - must convene and answer only two questions: (a) was the conduct caused by, or substantially related to, the student's disability; and (b) was the conduct the direct result of the district's failure to implement the IEP.
2. Weapon as a special circumstance. A knife is a dangerous weapon under IDEA's special-circumstances provision, which permits removal to an interim alternative educational setting for up to 45 school days regardless of the manifestation determination. But the MDR still must occur within the 10-school-day window; the exception changes the placement authority, not the procedural requirement.
3. Services during removal. Devon remains entitled to a free appropriate public education - the services and modifications needed to enable progress on IEP goals and in the general curriculum - not a bare suspension with no services. Confirm in writing who delivers what and where.
4. FBA and BIP review. The current BIP targets off-task behavior and frustration, not weapon carrying; a functional assessment of the relevant behavior and an updated BIP should be on the table.
5. Procedural safeguards provided to the mother, in her language, with an explanation of her right to disagree and to request a due process hearing. The alternative-school placement for the remainder of the year cannot be imposed as a disciplinary change beyond the permitted period without the proper determination.
6. Documentation of all of the above, including the dates.

Note that the 10-day suspension itself is within the general 10-school-day limit, but adding the alternative placement converts it into a change of placement that triggers the MDR and services.

Work through each question with evidence, and be explicit that the answer is not obvious from the disability label alone.

Question 1 - caused by or substantially related to the disability. The ADHD and written expression disability do not themselves explain carrying a knife. The relevant evidence is about impulsivity, social problem-solving, threat appraisal, and planning. Devon's account - that he was jumped and wanted protection - describes a reasoned plan over at least a day, which cuts against impulsivity as the cause; that is a legitimate consideration. Against that, the record should be examined for whether his disability affects his judgment under threat, whether he has a history of misreading social situations, and whether the BIP addressed any of this. The mother's fishing explanation and Devon's account conflict and must be reconciled through interview, not assumed. The team also must not let the nature of the weapon alone drive the finding; the legal question is about the disability's relationship to the conduct, not about how serious the conduct was.

Question 2 - direct result of failure to implement the IEP. This is where the file usually decides the case. Pull the BIP implementation data: was the plan actually run, with fidelity, in the weeks before Tuesday? If the BIP was not implemented, the second question must be answered yes, and the conduct is a manifestation regardless of the first answer. If it was implemented, document that with logs.

Record the team's reasoning, the evidence relied on, and any disagreement. If the team finds manifestation, the standard disciplinary change of placement is limited and a functional behavioral assessment and behavior plan follow. If not, the 45-day interim alternative educational setting remains available for the weapon, with services.

Both requests test role clarity, and the psychologist can honor both without compromising the process.

On the principal's request: decline to give a pre-meeting recommendation on the manifestation question. The MDR is a team decision that includes the parent, and offering a conclusion in advance risks predetermination - a finding that can invalidate the meeting and is difficult to defend. What the psychologist can legitimately do is prepare the evidence: the BIP implementation logs, discipline history, the prior FBA, and a summary of Devon's disability-related needs. Say something like: “I'll bring the implementation data and we'll work through both questions with his mother on Monday. I'm not going to prejudge it.” If pressed, note that the district's own case is stronger when the record shows a genuine team process. Separate the case-management role from any informal advisory role; do not act as both the person assembling the district's position and the person evaluating it.

On the mother's request: provide the BIP implementation data and any records she requests, promptly, subject to the district's records procedures and any state timeline. Do not filter to favorable documents, and do not require her to justify the request. Offer to walk her through the data before the meeting, provide the procedural safeguards notice, and confirm the meeting time and interpreter needs in writing. If the mother's account (the fishing trip) conflicts with Devon's, the team should interview both rather than choose one - and record that they did.

Document both conversations, the records provided, and the date.
