Vanderbilt Scoring Calculator

The Vanderbilt Assessment Scale is a diagnostic aid used by healthcare professionals to help evaluate children for Attention-Deficit/Hyperactivity Disorder (ADHD) and other co-occurring conditions. It is typically completed by parents and teachers. This calculator provides a way to sum the scores from the various sections of the Vanderbilt Assessment Scale (Parent or Teacher version) to help interpret the results. It is important to remember that this calculator is a tool for scoring and does not provide a diagnosis. A comprehensive evaluation by a qualified healthcare professional is always necessary for diagnosis and treatment planning.

For each symptom item, please select the rating that best describes the child's behavior over the past 6 months:

  • 0 = Never or Rarely
  • 1 = Occasionally
  • 2 = Often
  • 3 = Very Often

For performance items, please select the rating that best describes the child's functioning:

  • 1 = Excellent
  • 2 = Above Average
  • 3 = Average
  • 4 = Somewhat of a Problem
  • 5 = Significant Problem

Part A: Inattention Symptoms (Items 1-9)

Rate how often the child exhibits these behaviors (0-3):

0 – Never or Rarely 1 – Occasionally 2 – Often 3 – Very Often
0 – Never or Rarely 1 – Occasionally 2 – Often 3 – Very Often
