How to Get a Child Evaluated for ADHD

Starting with the pediatrician

For most families, the ADHD evaluation begins at the well-child visit or a dedicated behavioral health appointment with the pediatrician or nurse practitioner. The clinician will ask about attention, impulsivity, hyperactivity, and how long these patterns have been present. They will also want to rule out other causes — sleep problems, vision or hearing issues, anxiety, or stressors at home — before focusing on ADHD specifically.

The American Academy of Pediatrics 2019 clinical practice guideline recommends that primary care clinicians initiate an ADHD evaluation for any child aged 4 through 18 who presents with academic or behavioral problems and symptoms of inattention, hyperactivity, or impulsivity 1Ref 1Wolraich ML, Hagan JF, Allan C, et al. (AAP Subcommittee on Children and Adolescents with ADHD) (2019).Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents.AAP recommends ADHD evaluation for children aged 4–18 with academic or behavioral problems; multi-setting teacher rating scales are essential; treatment includes behavior therapy, parent training, and medication based on age and severity. Parents can come prepared with notes: specific examples of the behaviors, how often they occur, and when they first noticed them.

Rating scales: what they are and who fills them out

A core part of any ADHD evaluation is standardized rating scales — questionnaires that ask parents and teachers to rate how often certain behaviors appear. Commonly used tools include the Vanderbilt Assessment Scales and the Conners scales, though the specific form varies by practice. Because ADHD by definition causes problems in more than one setting, teacher input is considered essential 1Ref 1Wolraich ML, Hagan JF, Allan C, et al. (AAP Subcommittee on Children and Adolescents with ADHD) (2019).Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents.AAP recommends ADHD evaluation for children aged 4–18 with academic or behavioral problems; multi-setting teacher rating scales are essential; treatment includes behavior therapy, parent training, and medication based on age and severity. The CDC notes that about 9 in 10 children with an ADHD diagnosis had behavior rating scales used and about 8 in 10 evaluations incorporated information from an adult other than a family member 2Ref 2Centers for Disease Control and Prevention (2024).Data and Statistics on ADHD.About 9 in 10 children diagnosed with ADHD had behavior rating scales used; 8 in 10 evaluations incorporated adult informants other than family; approximately 7 million (11.4%) US children aged 3–17 ever diagnosed with ADHD (NSCH 2022). Parents will typically receive forms to bring to school, and the teacher returns them directly to the clinician.

When a referral is recommended

Many pediatric practices are comfortable completing a straightforward ADHD evaluation in-house. A referral to a developmental pediatrician, child psychologist, or pediatric neuropsychologist is more likely when the picture is complex — for example, if there are concerns about learning disabilities, autism spectrum traits, significant anxiety, or when the diagnosis is genuinely uncertain after standard evaluation. Neuropsychological testing, which is more extensive, can tease apart ADHD from look-alike conditions and identify co-occurring learning differences. These evaluations can have longer wait times in many areas, so families are encouraged to initiate the process early.

What school-based evaluation can and cannot do

Public schools are required to evaluate children for disabilities — including learning and attention issues — at no cost to families under federal law 3Ref 3U.S. Department of Education (2025).Frequently Asked Questions: Section 504 Free Appropriate Public Education (FAPE).Federal law requires public schools to evaluate children for disabilities at no cost; parents can request evaluation and have due-process protections if the school denies. A parent can submit a written request to the school for an educational evaluation, and the school must respond within a specific timeframe. However, a school evaluation determines eligibility for educational supports (like an IEP or 504 plan); it does not provide a medical ADHD diagnosis. Both tracks can run in parallel and complement each other. Medical evaluation is needed if treatment such as medication is being considered.

After the evaluation: what the results mean

At the end of the evaluation, the clinician will discuss findings with the family. If ADHD is identified, the conversation will cover which presentation fits — inattentive, hyperactive-impulsive, or combined — and what support options look like. The 2019 AAP guideline recommends a combination approach: behavior therapy (especially for younger children), parent training, school accommodations, and in some cases medication depending on the child's age and severity of impact 1Ref 1Wolraich ML, Hagan JF, Allan C, et al. (AAP Subcommittee on Children and Adolescents with ADHD) (2019).Clinical Practice Guideline for the Diagnosis, Evaluation, and Treatment of Attention-Deficit/Hyperactivity Disorder in Children and Adolescents.AAP recommends ADHD evaluation for children aged 4–18 with academic or behavioral problems; multi-setting teacher rating scales are essential; treatment includes behavior therapy, parent training, and medication based on age and severity. A diagnosis is a starting point for support, not a final label. Ongoing monitoring is part of appropriate care.
