Introducing the Test of Variables of Attention (T.O.V.A.®)

A computerized, objective measure of attention and inhibitory control normed by gender for ages 4 to 80+.

What is the T.O.V.A.?

The T.O.V.A. objectively measures the key components of attention and self-control, variability (consistency), response time (speed), commissions (impulsivity), and omissions (focus and vigilance). The T.O.V.A. provides information that is not available through self-report or the report of others. It can be used along with subjective measures for a more comprehensive picture of academic, social, and personal performance. The T.O.V.A. does not make a diagnosis.
