ADHD Testing

Test of Variables of Attention (T.O.V.A.) An FDA-cleared, computerized, and objective measure of attention and inhibitory control normed by gender for ages 4 to 80+ also known as Attention-Deficit/Hyperactivity Disorder (ADHD).

About The Test

The test provides healthcare professionals an objective measurement of attention and inhibitory control. The visual aids in the assessment of, and evaluation of treatment for, attention deficits, (ADHD). The auditory aids in the assessment of attention deficits where results are only interpreted by a qualified professional.

The T.O.V.A. is a culture and language-free, sufficiently long computerized test that requires no left/right discrimination or sequencing. T.O.V.A. calculates response time variability (consistency), response time (speed), commissions (impulsivity), and omissions (focus and vigilance). These calculations are then compared to a large age and gender-matched normative sample, as well as to a sample population of individuals independently diagnosed with ADHD. These comparison results are used to create an immediately available, easy-to-read report.

The T.O.V.A. provides information that is not available through self-report or the report of others. It is used along with a clinical interview and subjective measures (such as behavior ratings) for a more comprehensive picture of academic, social, and personal performance and impairment. T.O.V.A. results should only be interpreted by qualified healthcare professionals


T.O.V.A shares one of the most common traits seen in ADHD: inconsistency of performance measured with millisecond accuracy:

  • Pre-school test (ages 4 – 5.5)
  • School-age test (ages 5.5 – 17)
  • Adult test with embedded performance validity (ages 17 – 80+)
  • Visual and Auditory Test formats
  • Immediately available, easy to read report
  • FDA cleared and CE Medical Device Directive compliant
