Manifestation Determination After a Chair-Throwing Incident
Marcus is a 15-year-old 10th grader with an IEP for emotional disability. His IEP includes a BIP built around a token economy and check-in/check-out, but the district has never conducted an FBA. This year he has received nine suspensions totaling 23 school days, mostly for verbal aggression and leaving class. Last Tuesday, during algebra, he argued with a peer, then threw a chair toward the wall; no one was injured, but the class was evacuated. The principal recommends expulsion and a 45-day interim alternative educational setting. Marcus reads at a fourth-grade level and receives most instruction in general education. His mother insists the chair throwing was caused by his disability and that the school has failed to implement the BIP. The IEP team meets in three days. The district wants to move quickly because of staff safety concerns and parent pressure.
1. Apply the IDEA manifestation determination test to Marcus's chair-throwing incident. What conclusion is defensible, and which facts matter most?
Read the worked answer
The IEP team must answer two separate questions: (1) Was the conduct caused by, or did it have a direct and substantial relationship to, Marcus's emotional disability? (2) Was the conduct the direct result of the district's failure to implement the IEP? A yes to either makes the conduct a manifestation. The strongest facts here are the disability's core features (emotional regulation, reactivity to conflict), the escalating pattern of suspensions, the absence of any FBA, and the questionable fidelity of the token economy and check-in/check-out. A chair thrown after a peer argument is not automatically a manifestation, but the team cannot rely on the label of the act alone. It needs ABC data, staff interviews, and BIP implementation records. If the BIP was not followed, the second prong is satisfied even if the first is debatable. A defensible conclusion is that the conduct is a manifestation, or at minimum that the record is too incomplete to find otherwise; the team should not proceed to expulsion.
2. Evaluate the proposed 45-day IAES. Is it legally available here, and what should the team do instead?

A 45-day IAES is available without parent agreement only for weapons, illegal drugs, or serious bodily injury, or when a hearing officer finds a substantial likelihood of injury. A chair thrown toward a wall with no injury may be dangerous, but it does not fit the serious-bodily-injury category on these facts. If the conduct is a manifestation, the district cannot impose a disciplinary change of placement for that conduct. The team should instead conduct an FBA, revise the BIP, add a crisis/safety plan, increase supervision during algebra, and teach an escape/help-seeking replacement. It should document the threat assessment and any temporary emergency measures. If staff safety cannot be managed, the district can seek a hearing officer's order for an IAES or use short-term removal consistent with IDEA, but it should not label the 45-day placement as routine discipline. The mother must receive prior written notice and procedural safeguards.
3. What data should the IEP team gather before revising the BIP, and how should it respond to the mother's disagreement?
Read the worked answer
The team needs a functional behavior assessment, not another consequence plan. Data should include ABC records across algebra, transitions, and less structured settings; direct observations; suspension and nurse records; academic and reading data; teacher and student interviews; BIP fidelity checks; and information from the mother about sleep, medication, and stressors at home. The team should compare incidents where Marcus escalated with those where he used a coping strategy. Because the mother disagrees, the district must provide procedural safeguards, explain the MDR in plain language, and offer mediation or a facilitated IEP meeting. If she requests an independent educational evaluation, the district must respond under IDEA. Stay-put may apply during a dispute. The conversation should focus on safety and skill-building, not on blaming her or predicting expulsion.
