    About Child ADHD Testing

    What these scales measure, who they are for, and how to read your score.

    SNAP-IV vs Vanderbilt

    SNAP-IV (Swanson, Nolan, Pelham) and the Vanderbilt ADHD Diagnostic Rating Scale are the two most widely used free, public-domain rating scales for childhood ADHD. SNAP-IV is shorter and focuses on the 18 DSM-5 ADHD symptoms plus oppositional behaviors. Vanderbilt — recommended by the American Academy of Pediatrics — additionally screens for functional impairment and, in its full form, for co-occurring conduct, anxiety, and depressive symptoms that are common in children with ADHD.

    Who this test is for

    These scales are designed for parents, teachers, or caregivers of children aged roughly 6 to 12. The behaviors described should be present for at least 6 months and noticeably interfere with everyday life at home or at school. ADHD cannot be diagnosed from a single questionnaire: a clinician will combine parent and teacher ratings, a developmental history, and a physical exam to rule out vision, hearing, sleep, learning, or emotional issues that can mimic ADHD symptoms.

    What your score means

    Each item is rated 0–3. For Vanderbilt, six or more "Often / Very Often" answers in the inattention or hyperactivity cluster — together with at least one impaired life area — meets the symptom criteria for that presentation. SNAP-IV uses average sub-scale scores, with cutoffs around 1.78 for inattention and 1.44 for hyperactivity-impulsivity. A "positive" screen is not a diagnosis: it indicates that a clinical evaluation is warranted.

    Frequently Asked Questions

    Is this child ADHD test free?

    Yes. Both the SNAP-IV and the Vanderbilt scales are in the public domain and free to use. We do not require an account, email, or payment.

    Which assessment should I choose?

    If you only have a few minutes and want a quick screen of core symptoms, choose SNAP-IV. For a balanced general-purpose check, choose the Vanderbilt Short. If you want the most thorough screen — including possible co-occurring conditions — choose the Vanderbilt Full.

    Can a single questionnaire diagnose ADHD in my child?

    No. ADHD diagnosis requires evidence in two or more settings (typically home and school), a clinical interview, and ruling out other causes. Use this result as a structured starting point for a conversation with your pediatrician.

    What ages does this cover?

    These scales are validated for school-aged children, roughly 6 to 12 years old. Pre-schoolers and adolescents need different instruments — talk to a pediatric specialist.

    Should the teacher fill in a copy too?

    Yes — clinicians look for symptoms that show up in more than one setting. After completing this test you can download the official NICHQ teacher version PDF and ask your child's teacher to fill it in.
