ADHD answers
PublishedCan the Vanderbilt diagnose ADHD?
No. The Vanderbilt is a rating scale, so it records what a parent and a teacher observe. Diagnosis is a clinical judgement that also weighs history, development, school information and other possible explanations. A high score signals a conversation worth having, not a conclusion.
Key points
- Rating scales contribute evidence; clinicians make diagnoses.
- Other explanations, sleep, hearing, vision, anxiety, learning differences, life events, must be considered.
- Scores from one setting alone are weak evidence.
- Repeat measurement matters more than a single result.
The fuller answer
An ADHD evaluation asks whether a pattern is persistent, present in more than one setting, and interfering with functioning. A single questionnaire cannot answer all three on its own.
That is why providers ask for both a parent and a teacher form, and why they revisit the picture rather than deciding from one snapshot.
What to do next
Bring structured observations from both home and school to your next appointment.
