My Child Just Got Diagnosed: What to Do in the First 30 Days

You just heard words you'll remember forever. Maybe it was a psychologist reading off scores in a conference room, or a pediatrician saying "based on what we're seeing..." Either way, you walked out with a piece of paper and a head full of questions.

Here's the thing no one tells you in that appointment: the diagnosis you just received is not a school document. It's medical evidence. Before your child gets a single service at school, an entirely separate process has to happen — and you are the one who sets it in motion. This article walks you through exactly what to do, in what order, so you're not spinning your wheels in the weeks after that appointment.

The Diagnosis Is the Starting Gun

A lot of parents assume that once their child has an official diagnosis — ADHD, autism, dyslexia, SPD, anxiety — the school automatically receives some kind of notification and services appear. That's not how it works.

Your private evaluation (from a neuropsychologist, developmental pediatrician, or licensed psychologist) is independent from the school system. It's evidence that something is going on — often very detailed, expensive, and hard-won evidence. But the school is not obligated to simply adopt the conclusions of a private evaluator. They have their own legal process, and they cannot begin that process without a formal written request from you.

Think of the diagnosis as the starting gun: the race hasn't begun until you fire it. Your first job is to write that letter.

Week One: Request the Evaluation in Writing

The single most important thing you can do in the first week is send a written request for a full and individual evaluation. Email is fine — it creates a timestamp. A letter sent by certified mail is better. A combination of both is best.

Address the letter to two people: your child's principal and the district's Director of Special Education (sometimes called the Director of Pupil Services or Special Services). In the letter, state clearly:

• Your child's name, school, and grade
• That you suspect your child has a disability that affects their educational performance
• That you are requesting a full and individual evaluation under the Individuals with Disabilities Education Act (IDEA)
• Any areas you want evaluated (academic, cognitive, social-emotional, speech-language, occupational therapy, etc.)

Once the school receives your written request, they are required to respond. They must either agree to evaluate and provide you with an assessment plan for your consent, or send you written notice declining to evaluate — with a written explanation of why. Either way, you should receive a response within a timeframe set by your state (see the state-specific notes below).

After you receive the assessment plan and sign your consent, the clock starts on the evaluation timeline. Under federal law (IDEA, 34 CFR 300.301), the school must complete the evaluation within 60 days of receiving your written consent. Many states set shorter timelines — Massachusetts requires completion within 30 school working days; New York uses a 60-school-day window from consent to initial services. Check the state notes on this page for your state's specific rules.

Gather Your Documentation

While the school's evaluation process is underway, build your documentation file. This is the packet you bring to every meeting, keep in your car, and refer to during IEP discussions.

What to gather:

• Your private evaluation report — the full report from the psychologist, not just the summary page. This typically includes testing scores, observations, and recommendations.
• Medical records — diagnosis letters, medication records, any relevant treatment notes from therapists or specialists.
• School records — report cards, progress reports, teacher comments, any referrals to the principal's office or documentation of struggles. You can formally request your child's cumulative school file — the school must provide it.
• Your own notes — a running log of observations at home, incidents you've witnessed, or concerns teachers have expressed informally. Date every entry.
• Previous evaluations — if your child has had a speech evaluation, occupational therapy screening, or any prior school-based assessment, include those too.

The school's evaluators are required to review outside evaluations and consider them in their findings (34 CFR 300.304(b)(1)). Bring your private report to every meeting. It is not optional information — it is evidence they are legally obligated to consider.

Understand What the School Will Evaluate

The school evaluation has a different goal than your private evaluation. A private neuropsychologist is answering: "What does this child's profile look like, and what do they need?" The school is answering a specific two-part legal question:

1. Does your child have a disability that adversely affects educational performance?
2. Does your child need specially designed instruction (special education) as a result?

Both must be true for your child to qualify for an IEP. A child can have an ADHD diagnosis and still be found ineligible if the school determines the ADHD is not affecting educational performance. (This happens — and it's why your documentation matters.)

A comprehensive school evaluation may include:

• Cognitive assessment — IQ testing, processing speed, working memory
• Academic achievement testing — reading, math, writing
• Social-emotional assessment — behavior rating scales, interviews
• Speech-language evaluation — if communication concerns are suspected
• Occupational therapy evaluation — if fine motor, sensory, or daily living skills are a concern
• Classroom observations
• Teacher and parent interviews

You have the right to be part of the conversation about what areas the school evaluates. If you believe an area is being missed, say so in writing.

What If They Say Your Child Doesn't Qualify?

It happens. Sometimes a school evaluates and finds that — by their measure — the disability doesn't rise to the level of adversely affecting educational performance, or that your child's needs can be met in general education without an IEP.

A "no" is not the end of the road. You have options: you can request an Independent Educational Evaluation (IEE) at district expense, ask for a 504 Plan as an interim measure, file a state complaint, or request mediation.

AuDHD, 2e, and Multi-Diagnosis: Know This Rule

More and more children are coming to the IEP table with multiple intersecting diagnoses — autism plus ADHD (sometimes called AuDHD), twice-exceptional (2e) profiles with both giftedness and learning disabilities, sensory processing disorder alongside anxiety, or ADHD alongside dyslexia. If this is your child, there is a specific rule you need to know.

Federal law requires the school to evaluate in all areas of suspected disability (34 CFR 300.304(c)(4)). This means that if your child has both an autism diagnosis and ADHD, the school must evaluate the impact of both — not just whichever one appeared on the referral. If you suspect sensory processing issues, executive function challenges, communication differences, or social-emotional needs, name each one explicitly in your written evaluation request.

This matters because the school's evaluation drives the IEP. If they only assess for one diagnosis, they may only recommend supports for one set of needs — and your child's full picture gets missed. For children with autism, see our article Autism and the IEP; for ADHD-specific guidance, see ADHD and the IEP.

What to Expect at the Eligibility Meeting

After the school completes its evaluation, they will invite you to an eligibility meeting. This is the meeting where the team reviews the evaluation findings and makes two decisions: whether your child is eligible for special education, and — if eligible — what disability category they qualify under.

IDEA recognizes 13 disability categories, including Specific Learning Disability (SLD), Other Health Impairment (OHI, which covers ADHD), Autism Spectrum Disorder, Speech or Language Impairment, Emotional Disturbance, and others. Your child doesn't need to "fit" cleanly into one category — they only need to qualify under one to receive an IEP. Some children qualify under multiple categories.

At the eligibility meeting:

• The school will present evaluation results — you should receive copies before the meeting, not handed to you in the room
• The team will discuss whether the disability adversely affects educational performance
• If eligible, the team will note the disability category and move forward toward an IEP meeting (usually scheduled at the same time or shortly after)
• You are a full member of this team — you can ask questions, share your perspective, and disagree

You have the right to bring a support person with you — a friend, family member, advocate, or educational attorney. You don't need to explain why. If you've never been to one of these meetings, consider it.

Once your child has an IEP, IEP Says breaks down every section in plain language — what it means, what to ask for, and where it falls short. Upload your document for a free analysis and get a plain-language report on your child's goals, services, and rights.

Once an IEP is developed, the school must re-evaluate your child at least every three years (called a triennial reevaluation) to confirm eligibility and update the educational picture. Learn more: IEP Triennial Reevaluation: What Parents Need to Know.

Your Action List

1. Write the letter this week. Send a written request for a full and individual evaluation to both the principal and the Director of Special Education. Email with delivery confirmation, or certified mail. Keep a copy and note the date.
2. Build your documentation packet. Gather your private evaluation, medical records, school records, and any notes you have. Organize by date. Make two copies — one for meetings, one at home.
3. Review the assessment plan when it arrives. The school will send you a proposed assessment plan explaining what they intend to evaluate. Read it carefully. If areas are missing, write back and name the missing areas before you sign consent.
4. Sign consent promptly. Once you're satisfied with the assessment plan, sign and return it. Your signature starts the evaluation clock. Delays from you delay your child.
5. Request evaluation reports in advance of the meeting. You are entitled to receive a copy of the school's evaluation report before the eligibility meeting — not handed to you as you sit down. Ask for it at least a few days early.
6. Prepare your questions for the eligibility meeting. Write them down ahead of time. Ask about every area of need your child has. Take notes or ask if you can record.
7. Know what comes next. If eligible, the school must develop an IEP — a full meeting with the team to write your child's goals, services, and placement. That's a separate meeting (often the same day or shortly after), and it's where the real advocacy begins.
