Software: T.O.V.A.-Additional tests, each:

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.
