Quotient ADHD Test

Objective, Evidence-Based Data to Inform Your ADHD Diagnosis

The Quotient ADHD System is an innovative device that objectively measures three core symptom domains of ADHD: hyperactivity, inattention and impulsivity. Based on research from the McLean Hospital, a Harvard Medical School Affiliate, this easy-to-administer tool uses advanced motion tracking technology to track a child or adult’s micromovements while they complete a computerized test that takes less than half an hour.


After the test is completed, patterns of motion, accuracy of the responses, and fluctuations in attention state are quickly analyzed and scored using proprietary algorithms. Scores and test data provide you with valuable insights into both the existence of ADHD-related deficits and the magnitude of those deficits compared to expectable results from typically developing children of the sameage and gender.

Quotient is cleared by the FDA with the intended use “to provide clinicians with objective measures of hyperactivity, impulsivity and inattention to aid in the clinical assessment of ADHD”.
