How to Request an ADHD Evaluation from School (and What Happens Next)

The single most common mistake parents make at the start of the special education process is asking the teacher or school counselor — verbally — whether their child might need an evaluation. A verbal request does nothing. It creates no paper trail, triggers no legal timeline, and generates no obligation for the school to respond within any particular timeframe.

The moment you put a written request for an educational evaluation in front of the right person, you start the clock on the school's legal obligations.

Who to Address the Request To

The request should go to two people simultaneously: the school principal and the district's Director of Special Education (sometimes called the Director of Special Services or Director of Student Support). Send it by email with a read receipt, or by certified mail, or deliver it in person with a date-stamped copy for your records.

Do not send it only to the classroom teacher. Teachers cannot authorize evaluations and have no legal authority to begin the process. The teacher's observations are valuable evidence — but the request itself must go to the administrators who control the process.

What the Request Should Say

You do not need a lawyer to write this letter. The legal threshold is that you suspect your child has a disability that is affecting their educational performance. Here is the essential structure:

"I am requesting that [child's name] be evaluated for special education eligibility under the Individuals with Disabilities Education Act (IDEA). I suspect [child's name] has a disability — specifically, Attention Deficit Hyperactivity Disorder — that is adversely affecting their educational performance. I am requesting a comprehensive evaluation including cognitive, academic, executive function, behavioral, and social-emotional assessments. Please provide me with the parental consent form for evaluation."

State the date. State that this is a formal written request. That is sufficient to start the clock.

What Happens After the Request

Once the school receives a written request for evaluation, the process under IDEA unfolds in two stages:

Stage 1 — Consent: The school must respond with a formal notice that either agrees to conduct the evaluation or explains in writing why it is refusing. If the school agrees, it provides a Prior Written Notice describing what it intends to evaluate, which assessments will be used, and why. The parent then signs the consent form.

Stage 2 — Evaluation: Once the parent signs consent, the school typically has 60 school days (some states use calendar days or different timeframes — check your state's specific rule) to complete the evaluation and hold an eligibility determination meeting. At that meeting, the IEP team reviews the evaluation results and decides whether the student qualifies for special education.

If the school says it needs to "observe the student first" or wants to try prereferral interventions before evaluating, ask whether that is delaying the evaluation. Under IDEA, prereferral interventions are not a legal prerequisite to a parent-requested evaluation. If the school is deliberately using a Response to Intervention (RTI) process to delay an evaluation, this can be grounds for a state complaint.

What the School Evaluation Should Include for ADHD

A school evaluation that produces only an IQ test and a brief teacher rating scale is inadequate for ADHD. A thorough evaluation for ADHD eligibility should include:

• Cognitive assessment (e.g., WISC-V) — including the processing speed index, which is frequently depressed in ADHD and is critical for justifying extended time accommodations
• Academic achievement testing — to identify any co-occurring specific learning disabilities
• Executive function assessment — the BRIEF-2 (Behavior Rating Inventory of Executive Function) specifically, which maps working memory, initiation, planning, and monitoring deficits directly to accommodation needs
• Behavioral rating scales — multi-informant (parent, teacher, and where appropriate, student) using validated tools such as the Conners-4 or Vanderbilt scales
• Observations — direct observation in at least two settings (classroom and one other)
• Social-emotional screening — to identify co-occurring anxiety or depression that frequently masks or complicates ADHD

If the school's evaluation does not include these components, ask during the eligibility meeting what assessments were used and why specific tools were omitted. The evaluation must be "comprehensive" under IDEA — it cannot focus only on one area of suspected disability.

What to Do If the School Refuses to Evaluate

If the school refuses the evaluation request, it must issue a Prior Written Notice — a written explanation of the refusal that includes the reason for refusal, the data used to support that decision, and the alternatives considered.

Common refusal reasons and responses:

• "The student's grades are fine" — Academic performance is one dimension of educational performance. Social-emotional functioning, behavioral regulation, and organizational ability are also part of educational performance under IDEA. Provide documentation of executive function challenges at home.
• "We'll try interventions first" — Parents may request an evaluation at any time regardless of what interventions are or aren't in place. IDEA does not require exhaustion of interventions before a parent can request an evaluation.
• "The student hasn't been diagnosed yet" — A diagnosis is not required to request an evaluation. The suspicion of a disability is sufficient to trigger the obligation to evaluate.

If the school refuses without adequate grounds, file a state complaint with your state Department of Education's special education division. This is separate from a due process hearing — it is faster, free to file, and results in an investigation within 60 days.

Independent Educational Evaluations (IEE) at Public Expense

If the school completes the evaluation and you disagree with the results — you believe the evaluation is inadequate, used the wrong tools, or failed to capture the true impact of the ADHD — you have the right under IDEA to request an Independent Educational Evaluation (IEE) at public expense.

This is one of the most powerful and least-known parent rights in special education. To invoke it:

1. Write to the school: "I disagree with the school's evaluation and am requesting an Independent Educational Evaluation at public expense."

Upon receiving this request, the school has two options:

• Fund the IEE — pay for a private neuropsychological or psycho-educational evaluation conducted by an evaluator you choose (from a list the school provides, or with school agreement on the evaluator)
• File for due process — go to a hearing to defend the adequacy of its own evaluation

If the school chooses neither — if it neither funds the IEE nor files for due process — it is in violation of IDEA.

A private neuropsychological evaluation typically costs between $3,000 and $5,000. When the school funds the IEE, they absorb that cost. The resulting evaluation carries significant weight at any subsequent IEP or eligibility meeting — it is evidence the school is obligated to consider.

A Note for Families Outside the US

Canada: Parents must navigate the provincial identification process. In Ontario, requesting an Identification, Placement, and Review Committee (IPRC) in writing is analogous to requesting an evaluation under IDEA. In British Columbia, parents can request a formal assessment through the school district. Timelines and rights vary by province.

UK: Request an EHC needs assessment in writing to the Local Authority rather than the school evaluation process. The LA responds within 6 weeks. During the wait, request that the school document SEN Support under the Assess, Plan, Do, Review framework.

Australia: Schools must conduct their own assessment and documentation process to qualify for NCCD funding. Parents can request to see the documentation supporting their child's classification level. If a private assessment has been conducted, submit it to the school and request a formal Individual Learning Plan (ILP) meeting.
