Quick Answer
If your child has a diagnosed disability and is receiving no support at school, the first step is to submit a written request for a special education evaluation under IDEA. The school must respond within a set timeframe and cannot deny the evaluation without a written explanation. You do not need the school to suggest it first — you can initiate the process yourself.
"I really don't know what to do anymore. My daughter has ASD and sensory processing disorder. She doesn't have any support at school. She's 5. She's only started acting out at school."

If your child has a diagnosed disability and is receiving no support at school, the first step is to submit a written request for a special education evaluation under IDEA. The school must respond within a set timeframe and cannot deny the evaluation without written explanation. You do not need to wait for the school to suggest it.
It is not a behavior problem. It is a support problem. And there are specific, concrete steps you can take — starting today — to change it.
This article walks you through exactly where to start: what the law requires your school to do, how to request an evaluation, whether your child needs an IEP or a 504 plan, and what "acting out" really means when a five-year-old with ASD and sensory processing disorder is left without help.
You Are Not Imagining It
Before we get into the legal steps, let us say something clearly: you are right to be concerned.
A five-year-old with autism and sensory processing disorder who is "acting out" at school is not suddenly developing behavioral issues out of nowhere. She is responding to an environment that is not designed for her nervous system — loud classrooms, unpredictable transitions, sensory overload, social demands she does not have the tools to navigate — without any support in place to help her cope.
You are not overreacting. You are not being "that parent." You are seeing what is obvious: your child has documented disabilities, she has no support, and she is struggling. The only question is what to do about it.
The answer starts with a single concept the school is legally required to follow — whether they have told you about it or not.
What Is Child Find — and Why It Matters Right Now
Child Find is a federal requirement under IDEA — the Individuals with Disabilities Education Act — that obligates every school district in the country to identify, locate, and evaluate all children who may have a disability and need special education services (34 CFR 300.111).
Read that again. The school does not get to wait for you to ask. The school does not get to say "she seems fine to us." If there is any reason to suspect a child might have a disability that affects their education, the school has a legal duty to act.
A child with a diagnosed disability who has no supports and is acting out at school is the textbook case for Child Find. The school should have already been reaching out to you — not the other way around.
- Child Find applies to every child. Enrolled students, homeschooled children, children in private schools, children not yet in school. Every child.
- It applies regardless of whether the parent has requested anything. The obligation is on the school, not on you.
- A medical diagnosis is a strong indicator. ASD and sensory processing disorder are exactly the kind of conditions that trigger Child Find obligations.
- "Acting out" behavior in a child with a known disability is a red flag. It signals that the child's needs are not being met — and the school should recognize that.
Step 1: Request an Evaluation in Writing
Do not wait for the school to come to you. Even though Child Find puts the obligation on the school, the fastest way to start the process is to request an evaluation yourself — in writing.
Under 34 CFR 300.301, a parent can request a special education evaluation at any time. You do not need a teacher referral. You do not need the school's permission. You do not need to go through a "student support team" first. You write the letter, and the school must respond.
Here is a sample letter you can adapt and send today:
Dear [Principal/Special Education Director],
I am writing to formally request that [child's name], a [grade] student at [school name], be evaluated for special education services under the Individuals with Disabilities Education Act (IDEA).
[Child's name] has been diagnosed with [diagnosis/diagnoses] and is currently struggling at school with [specific behaviors or challenges]. She does not currently receive any special education services or supports.
I am requesting a comprehensive evaluation to determine eligibility for an IEP, including but not limited to assessments in the areas of academics, behavior, sensory processing, social-emotional functioning, and speech/language.
Please provide me with the evaluation consent form within 10 business days of receiving this letter. I understand that under [state law reference], the evaluation must be completed within [timeline].
Thank you for your prompt attention to this request.
[Your name]
[Date]
cc: [Special Education Director, if different from recipient]
After the school receives your request, they must do one of two things:
- Agree to evaluate — and send you a consent form to sign. The evaluation cannot begin until you give written consent (34 CFR 300.300).
- Refuse to evaluate — and provide you with Prior Written Notice (PWN) explaining why they are refusing, what data they used, and what alternatives they considered. If they refuse, you have the right to challenge that decision.
The school cannot simply ignore the request. For a complete walkthrough of the evaluation process — including what to do if the school pushes back — see our step-by-step evaluation request guide.
IEP vs. 504 — Which Path Is Right for Your Child?
Once your child is evaluated, the team will determine eligibility for services. There are two main paths, and understanding the difference now will help you advocate effectively.
IEP (Individualized Education Program) — under IDEA
An IEP provides specially designed instruction — teaching that is adapted in content, methodology, or delivery to meet your child's unique needs. It also includes related services (like occupational therapy, speech therapy, or behavioral support), accommodations, goals, and progress monitoring.
To qualify for an IEP, a child must:
- Have a disability that falls under one of IDEA's 13 eligibility categories (autism is one of them)
- Need specially designed instruction because of that disability
For a five-year-old with ASD and sensory processing disorder who is struggling at school, an IEP is very likely the right path. Autism is a qualifying category under IDEA, and the behavioral struggles your child is showing strongly suggest a need for specialized support.
504 Plan — under Section 504 of the Rehabilitation Act
A 504 plan provides accommodations — changes to the environment or how instruction is delivered — but does not include specially designed instruction. It has a broader eligibility standard: any physical or mental impairment that substantially limits a major life activity (including learning, concentrating, and communicating).
A 504 plan might include things like sensory breaks, preferential seating, a quiet space to de-escalate, or modified transitions. These can be powerful supports. But a 504 does not come with the same level of legal protection, progress monitoring, or specialized instruction that an IEP provides.
Which one does your child need?
For a child with ASD and sensory processing challenges who is acting out at school with zero supports in place, start by requesting an IEP evaluation. If the evaluation determines your child qualifies for an IEP, that gives you the strongest protections and the most comprehensive support. If the team determines your child does not qualify for an IEP, a 504 plan is the fallback — and it is often still a meaningful step forward.
For a detailed comparison, read our guide to IEP vs. 504 plan differences. And if the school says your child does not qualify for an IEP, you have options — see "Your Child Doesn't Qualify" — What to Do Next.
What "Acting Out" Really Means
When a parent says their child is "acting out," most schools hear "behavior problem." But when a five-year-old with ASD and sensory processing disorder starts "acting out" at school, what is actually happening is very different from defiance.
Behavior is communication. Your daughter is telling the adults around her — the only way she knows how — that something in the environment is overwhelming, painful, confusing, or unsafe. She is not choosing to be difficult. Her nervous system is responding to an environment that was not designed for her.
For a child with ASD and sensory processing disorder, "acting out" might really mean:
- Sensory overload. The classroom is too loud, the lights are too bright, the textures are wrong, or there is too much going on at once. Her body goes into fight-or-flight because the sensory input is physically painful.
- Transition difficulty. Moving from one activity to another without warning or preparation triggers anxiety and dysregulation.
- Communication breakdown. She cannot express what she needs, so her body expresses it for her — through hitting, crying, running, or shutting down.
- Social confusion. The unspoken rules of a kindergarten classroom are invisible to her. She does not understand the social expectations, and the resulting confusion triggers distress.
- Exhaustion from masking. If she has been holding it together all day, the mask eventually cracks — and the school sees a "sudden" behavior that has actually been building for hours.
None of this is misbehavior. All of it is a signal that the child needs support — support that is not there.

What to Ask for in the Evaluation
When you request the evaluation, be specific about the areas you want assessed. A comprehensive evaluation for a child with ASD and sensory processing disorder should include:
- Cognitive/intellectual assessment — understanding your child's overall learning profile
- Academic achievement — where she stands in reading, writing, and math (even in kindergarten, there are age-appropriate benchmarks)
- Behavioral assessment — a Functional Behavioral Assessment (FBA) to understand what is driving the behavior, what triggers it, and what need it serves
- Sensory processing evaluation — typically conducted by an occupational therapist, this assesses how your child processes sensory input and what accommodations she needs
- Social-emotional functioning — how your child manages emotions, interacts with peers, and copes with stress
- Speech and language — including pragmatic (social) language, which is often affected in ASD even when expressive language seems "fine"
- Adaptive behavior — how your child manages daily living skills compared to age expectations
- Occupational therapy screening — fine motor skills, self-regulation, and sensory integration
You have the right to request assessments in all areas of suspected disability (34 CFR 300.304(c)(4)). If the school proposes a narrow evaluation — say, just academic testing — push back. Your child's struggles are not limited to academics, and the evaluation should not be either.
What Happens After the Evaluation
Once the evaluation is complete, the school will schedule an eligibility meeting with you and the evaluation team. Here is what happens:
- The team reviews the evaluation results. Every assessment is discussed. You are a member of this team — your input matters.
- The team determines eligibility. Does your child have a disability under one of IDEA's 13 categories? Does that disability adversely affect educational performance? Does the child need specially designed instruction? If the answer to all three is yes, your child qualifies for an IEP.
- If eligible, the team develops the IEP. This includes present levels of performance, annual goals, services (like OT, speech, behavioral support), accommodations, and placement. For a guide to what should be in the IEP, see IEP services explained.
- If not eligible for an IEP, ask about a 504. Do not leave the meeting without exploring this option. A child with ASD who does not meet IEP eligibility may still qualify for accommodations under Section 504.
- You must give consent before services begin. The school cannot start implementing the IEP until you sign. Take the time you need to review it — you do not have to sign at the meeting.
Know your rights throughout this process. You are an equal member of the IEP team, you can bring an advocate or support person, and you can disagree with any decision the team makes. For a full overview, see our guide to your IEP rights.
State-Specific Timelines: NH and MA
The federal default is 60 days from receiving parental consent to complete the evaluation (34 CFR 300.301(c)(1)). But your state may have different timelines. Here is what applies in New Hampshire and Massachusetts:
New Hampshire
- Evaluation timeline: 60 calendar days from the date of written parental consent (Ed 1107.01). This is the same as the federal default.
- Qualified examiners: Evaluations must be conducted by qualified examiners as defined under Ed 1107.04.
- Special education framework: RSA 186-C governs all special education in New Hampshire.
- Documentation note: New Hampshire is a one-party consent state for recording conversations — relevant if you want to document phone calls or meetings with the school.
Massachusetts
- Evaluation timeline: 45 school working days total from parental consent for the entire process — evaluations must be completed within 30 of those days, then the team meeting and eligibility determination within the remaining time (603 CMR 28.04(1)). Massachusetts moves faster than the federal 60-day timeline.
- Consent form: Parents sign an Evaluation Consent Form (N1 form) to authorize the evaluation.
- Special education law: MGL c.71B governs special education in Massachusetts.
- Stronger Child Find: Massachusetts has documented stronger Child Find obligations than the federal minimum.
- Dispute resolution: If the school refuses to evaluate or you disagree with results, you can contact the Bureau of Special Education Appeals (BSEA) at 781-397-4750.
What If the School Says "Let's Wait and See"?
This is the most common roadblock parents face — and it is not legal when there is reason to suspect a disability.
"Let's wait and see." "Let's try some classroom strategies first." "She's still adjusting to kindergarten." "She might just grow out of it."
These responses may sound reasonable. They are not — not when your child has diagnosed disabilities and is already struggling.
Child Find does not have a waiting period. The school's obligation to identify and evaluate children with suspected disabilities is not contingent on trying interventions first. While schools can and should use general education interventions (like Response to Intervention, or RTI), they cannot use RTI to delay or deny a parent-requested evaluation.
The federal Office of Special Education Programs (OSEP) has made this explicitly clear: a parent's request for evaluation triggers an obligation to respond — not to wait.
If the school tells you to wait:
- Point to the diagnosis. "My child has been diagnosed with ASD and sensory processing disorder. There is no question about whether a disability might be present. It has been documented."
- Point to the behavior. "My child is acting out at school. She is not receiving any support. The behavioral changes are evidence that her disability is affecting her education."
- Request Prior Written Notice. "If you are refusing to evaluate, I need that in writing. Please provide me with Prior Written Notice explaining why you are declining my request for evaluation."
- Cite Child Find. "Under 34 CFR 300.111, the school district has an obligation to identify and evaluate children suspected of having a disability. My daughter has a diagnosed disability and is struggling at school. I am formally requesting an evaluation under IDEA."
Most schools will agree to evaluate once you put the request in writing and cite the law. The ones that do not are taking a legal risk they usually cannot defend.
Your Next Steps
If your child has a disability, has no support at school, and is struggling — here is what to do, starting today:
- Write the evaluation request letter. Use the sample above. Send it by email to the principal and special education director. Print a copy and send it certified mail or hand-deliver it with a receipt. Keep a copy for yourself.
- Gather your documentation. Pull together your child's medical diagnoses, any private evaluations or therapy reports, and notes about what you are seeing at home and what the school has reported. This is your evidence file.
- Learn the timeline. In New Hampshire, the school has 60 calendar days from your written consent. In Massachusetts, 45 school working days total from consent for the entire process (evaluations within 30). Mark the deadline on your calendar and follow up if it passes.
- Understand your rights. You are an equal member of the IEP team. You can bring an advocate. You can disagree. You do not have to sign anything at the meeting. Read our guide to your IEP rights before the first meeting.
- Prepare for the IEP vs. 504 conversation. Know the difference before you walk in. Our IEP vs. 504 comparison guide explains what each one provides and when each one applies.
- If you already have an IEP, check it. Get started to get a plain-language breakdown of your child's supports — and specific language to bring to your next meeting.

Kentucky
Kentucky districts have a Child Find obligation under 707 KAR 1:300 to actively seek out and evaluate children who may be eligible for special education — including enrolled students not yet identified. You can submit a written evaluation request at any time. If the school declines, it must provide Prior Written Notice explaining why — you can then file a state complaint with OSEEL or request mediation.
Pre-referral RTI interventions are required before referral (707 KAR 1:300, Section 3), but the school cannot use this as an indefinite delay when disability is suspected.
