Your Child Isn't Misbehaving — They're in Fight or Flight

"My son is autistic and when he gets overwhelmed at school, he hits. The school keeps giving him in-school suspension. He's not being bad — he's scared. How do I get them to actually help him instead of punishing him?"

— Parent of a child with autism, via online support group

When a child covers their ears in the hallway, refuses to touch materials, runs from the classroom, or melts down during transitions — that is a neurological stress response, not misbehavior. The child's nervous system is reacting to perceived threat. The IEP team must address the root cause through sensory supports, an FBA, and a behavior intervention plan — not punishment.

Here is what nobody at the school is saying: your child is not misbehaving. Their nervous system is in survival mode. And punishing a survival response does not make it stop — it makes it worse.

This article explains what is actually happening in your child's brain during these moments, what the law requires the school to do instead, and exactly what you can ask for in the IEP to replace punishment with real support.

What Fight or Flight Actually Is

Fight or flight is not a behavior. It is a neurological event.

When your child perceives a threat — and "threat" can mean a loud cafeteria, an unexpected schedule change, a peer getting too close, or being called on in class — their brain's alarm system (the amygdala) fires. Stress hormones flood the body. The thinking, reasoning part of the brain (the prefrontal cortex) goes offline.

In that moment, your child has three options — none of which they are consciously choosing:

• Fight: hitting, kicking, throwing things, screaming, biting
• Flight: running out of the classroom, hiding, bolting from the building
• Freeze: shutting down completely, going nonverbal, refusing to move

This is not defiance. This is not manipulation. This is a child whose body has taken over because their brain has decided they are in danger.

Why some children are more vulnerable

Children with autism, ADHD, anxiety disorders, sensory processing differences, PTSD, and other neurological or emotional conditions often have a lower threshold for triggering fight or flight. Their nervous systems are wired to be more sensitive to stimuli that other children can brush off.

This means:

• The fluorescent lights that other kids ignore might be physically painful
• The noise level that other kids tolerate might be overwhelming
• The social demand that other kids navigate easily might feel impossible
• The transition that other kids handle smoothly might feel like the ground shifting

Your child is not weaker. Their nervous system is different. And a school environment that does not account for that difference is going to produce crisis after crisis.

What Schools Get Wrong

When a child hits, runs, or shuts down, many schools reach for the same playbook they use for every student: consequences. In-school suspension. Loss of recess. Isolation rooms. Phone calls home. Behavior contracts that amount to "stop doing that or else."

This does not work for children in fight or flight. It makes things worse.

Here is why:

• Punishment requires a thinking brain. A child in fight or flight cannot process consequences, learn from them, or connect their behavior to the punishment. The thinking brain is offline. You are punishing a reflex.
• Isolation increases distress. For a child who is already in a state of perceived danger, being removed from familiar people and placed in an unfamiliar room alone raises the alarm even higher.
• Suspension removes learning time. The child misses instruction, falls further behind, and returns to school with even more anxiety about being there — increasing the likelihood of another crisis.
• It teaches the wrong lesson. The child learns: "When I am at my worst, the adults who are supposed to help me will remove me." That is not safety. That is abandonment.

The cycle

It goes like this:

1. Child is overwhelmed (sensory, social, academic, emotional trigger)
2. Child enters fight or flight (hits, runs, shuts down)
3. School punishes the behavior (suspension, isolation, loss of privileges)
4. Child returns to school more anxious, more dysregulated, less trusting
5. Repeat

Nothing changes because the school is responding to the behavior (the symptom) instead of the trigger (the cause). And until someone asks why the behavior is happening, the cycle will not break.

What the Law Says

You are not just relying on common sense here. Federal law is on your side.

IDEA requires positive behavior supports

Under the Individuals with Disabilities Education Act (IDEA), when a child's behavior impedes their learning or the learning of others, the IEP team must "consider the use of positive behavioral interventions and supports, and other strategies, to address that behavior" (34 CFR 300.324(a)(2)(i)).

The word is positive. Not punitive. Not exclusionary. Positive.

If the school's primary response to your child's behavior is suspension, isolation, or removal — they are likely not meeting this requirement.

The FBA and BIP are required when behavior is a concern

When behavior is an issue, IDEA expects the IEP team to conduct a Functional Behavioral Assessment (FBA) and develop a Behavior Intervention Plan (BIP). The BIP must include proactive strategies — not just consequences — and be reviewed when behavioral concerns persist.

State-specific protections

Your state may go further than federal law. Here is what we know:

New Hampshire

• Aversive behavioral interventions are explicitly prohibited. Schools cannot use procedures that subject a child to physical or psychological harm, unsupervised confinement, or deprivation of basic needs like food, communication, or parental contact (Ed 1102.01(m)).
• Behavior intervention plans must use positive behavior supports and be incorporated into the student's IEP (Ed 1102.01(n); RSA 186-C:2, I-c).
• If an FBA exists, the IEP team must review it and ensure the BIP is appropriate (RSA 186-C:7, IV; Ed 1106.01(k)).
• Parents have the right to refuse proposed behavior interventions. If you do, the district must notify the NH Department of Education within 5 instruction days (RSA 186-C:7, VI).

Massachusetts

• An FBA must be conducted for students with disruptive or inappropriate behaviors (MGL c. 71B).
• For students on the autism spectrum, or whose disability affects social skills, the IEP team must automatically determine if the student is vulnerable to bullying, harassment, or teasing — and address it with specific goals and supports.
• The IEP must include specific provisions for high-risk times — lunch, recess, transitions, bus — through supplementary aides, staff training, and consultation.
• If the student is not making progress toward behavior goals, the team must reconvene to discuss changes.

What Should Be in the IEP Instead

If your child's IEP addresses behavior, it should not just say "will reduce aggressive behavior." That is meaningless. Here is what a real behavior support system looks like in an IEP:

1. A clear understanding of triggers (from the FBA)

The IEP should name the specific situations that trigger your child's fight-or-flight response. Not "unstructured time" — but "transitions between activities in the classroom, particularly when the schedule changes without warning."

2. Antecedent strategies (preventing the crisis before it starts)

• Visual schedule with advance notice of changes
• Sensory diet built into the day (movement breaks, fidgets, noise-canceling headphones)
• Pre-teaching for difficult situations ("In 5 minutes we are going to the assembly. It will be loud. You can wear your headphones.")
• Reduced demands during high-stress times
• A designated safe person the child can go to when they feel dysregulated

3. A de-escalation plan (when the crisis is building)

• A "break card" or nonverbal signal the child can use to leave a situation before it escalates
• A calm-down space that is accessible, not punitive (not an isolation room — a sensory-friendly space with preferred items)
• Specific staff-trained de-escalation techniques (co-regulation, reduced language, giving space)
• Clear protocol: what happens when the child uses the break card? Who goes with them? How long? How do they re-enter?

4. Replacement behaviors (teaching what TO do)

A good behavior plan does not just say "stop hitting." It teaches the child what to do instead when they feel overwhelmed:

• Asking for a break (verbally, with a card, or with a gesture)
• Going to the calm-down space independently
• Using a specific coping strategy (deep breathing, counting, squeezing a stress ball)
• Requesting help from a trusted adult

5. A crisis protocol (when fight or flight is already happening)

• Who responds? (Named staff members who are trained)
• What do they do? (Give space, reduce demands, ensure physical safety, no restraint unless imminent danger)
• How is the child supported after the crisis? (Recovery time, check-in, no immediate academic demands)
• How is the incident documented? (Behavior tracking log, not just a discipline report)
• How and when are parents notified?

6. Staff training

None of this works if the adults in the room do not know how to implement it. The IEP can — and should — specify that staff working with your child receive training in de-escalation, trauma-informed practices, and your child's specific behavior plan.

The FBA: Your Most Powerful Tool

The Functional Behavioral Assessment is the single most important step in breaking the punishment cycle. It answers the question that everything else depends on: why is this happening?

What a good FBA includes

• Direct observation data — someone watching the child in the actual settings where behavior occurs (not a checklist filled out from memory)
• Antecedent analysis — what happens immediately before the behavior? What triggers it?
• Consequence analysis — what happens immediately after the behavior? What does the child get or escape?
• Function of the behavior — what need is the behavior serving? (Usually: escape from demand, access to a preferred item/activity, sensory regulation, or attention/connection)
• Setting events — broader context that makes the behavior more likely (poor sleep, medication changes, family stress, illness, time of day)
• Input from you — what you observe at home, what works, what does not

Red flags in a weak FBA

• Based entirely on teacher reports — no direct observation
• Describes behavior as "noncompliant" or "defiant" without exploring the function
• Does not include parent input
• Completed by someone who has never met your child
• Results in a BIP that is just a list of consequences

How to request one

You can request an FBA at any time, in writing. Here is sample language:

Dear [Case Manager/Special Education Director],

I am writing to formally request a Functional Behavioral Assessment (FBA) for my child, [name]. [He/She/They] has been experiencing [describe the behaviors — e.g., "physical aggression during transitions" or "leaving the classroom when overwhelmed"] and the current approach is not reducing these behaviors.

I am requesting that the FBA include direct observation in the settings where these behaviors occur, analysis of triggers and functions, and input from me as a parent. I also request that a Behavior Intervention Plan (BIP) be developed based on the FBA findings and incorporated into the IEP.

Please let me know the timeline for completing this assessment. Thank you.

What to Say at the Meeting

You do not need to be a behavior specialist to advocate for your child. You need to ask the right questions and hold the team to what the law requires. Here are phrases you can use:

When the school frames behavior as defiance

"My child's behavior is communication, not defiance. I need the team to identify what my child is communicating and what support they need — not what consequence to give."

When the school has been suspending

"Suspension has not reduced this behavior. That tells me we are addressing the symptom, not the cause. I want an FBA to understand why this is happening, and a behavior plan built on that understanding."

When the BIP is just consequences

"I see what happens when my child misbehaves. What I don't see is what the adults do before the crisis to prevent it and during the crisis to de-escalate it. Can we add those pieces?"

When you want to know what de-escalation was tried

"Before the incident, what de-escalation strategies were attempted? Who intervened and what training have they had in de-escalation and trauma-informed responses?"

When the school says "we have to keep other students safe"

"I agree that all students deserve to be safe. My child also deserves to be safe — and right now, the plan is not keeping anyone safe. Let us figure out what supports will prevent these situations from happening in the first place."

When you want data

"Can you show me the behavior tracking data? I want to see when these incidents are happening, what the triggers are, and whether the current plan is actually reducing them over time."

If the School Suspends Anyway

Know your rights.

The 10-day rule

Under IDEA (34 CFR 300.530), a school can remove a child with a disability from their placement for disciplinary reasons for up to 10 school days in a school year without triggering additional protections. After that:

• The school must conduct a manifestation determination within 10 school days of the decision to remove the child
• The IEP team reviews the relationship between the child's disability and the behavior
• If the behavior was caused by or substantially related to the disability — the child must be returned to their placement (unless you and the school agree otherwise)
• If the behavior was not a manifestation — the school can discipline the child as it would any student, BUT must continue to provide FAPE (educational services) during the removal

Your rights during the process

• You must be notified of the decision to remove your child and provided a copy of your procedural safeguards
• You are a member of the manifestation determination team
• If the behavior is a manifestation and the school has not conducted an FBA, they must do one now
• If a BIP exists, it must be reviewed and revised
• You can challenge the school's decision through due process if you disagree with the manifestation determination

State-specific protections

New Hampshire: The school must follow IDEA discipline procedures under 34 CFR 300.530-532, as incorporated into state law via Ed 1124.01. If you reject a proposed change in placement, the district must notify the NH Department of Education within 5 instruction days (RSA 186-C:7, VI).

Massachusetts: If you disagree with the school's disciplinary decision, you can request a facilitated IEP meeting through the Bureau of Special Education Appeals (BSEA) at 781-397-4750, or file a complaint with the Department of Elementary and Secondary Education's Program Quality Assurance office within one year.

Your Next Steps

If your child is being punished for fight-or-flight responses at school, here is what to do — starting today:

1. Request an FBA in writing. Use the sample language above. Email it to the case manager and special education director. Keep a copy.
2. Review the current BIP (if one exists). Does it include antecedent strategies, de-escalation steps, replacement behaviors, and a crisis protocol? Or is it just consequences? If it is just consequences, ask for it to be rewritten.
3. Ask for a crisis de-escalation plan. This should name specific trained staff, specific steps, and a clear process for what happens before, during, and after a crisis.
4. Document every incident. Date, time, what happened, what the school did, who was involved. Keep a simple log. This is your evidence if you need to escalate.
5. Count the days. If your child has been removed from their placement for 10 or more school days total in a year, the school must conduct a manifestation determination. Make sure they do.
6. Upload your IEP. Join the waitlist to get a plain-language breakdown of your child's behavior supports — and specific language to bring to your next meeting.
