TOVA-Test of Variables of Attention for both PC & Macs



The Test of Variables of Attention (T.O.V.A.®) is a computerized test of attention that assists in the screening, diagnosis, and treatment monitoring of attention disorders, like Attention Deficit Hyperactivity Disorder (ADHD).
The T.O.V.A. is an objective, neurophysiological measure of attention, not a subjective rating of behavior. It is a 21.6 minute long, very simple "computer game" that measures your responses to either visual or auditory stimuli. These measurements are then compared to the measurements of a group of people without attention disorders who took the T.O.V.A.

The clinical version of the T.O.V.A. is used by licensed clinicians, such as psychologists, physicians (including psychiatrists, neurologists, pediatricians, and family practitioners), nurse clinicians, and licensed clinical social workers to assist them in accurately diagnosing and treating attention disorders.

The screening version of the T.O.V.A. is used in non-clinical settings, such as schools, human resource departments, and rehabilitation programs.

What makes the T.O.V.A. unique?
  • T.O.V.A. has a standardized computer game-like format and is easily administered.
  • Any personnel can be trained to administer the test.
  • Its reports are immediately available and easy-to-read.
  • It measures both visual and auditory information processing, yet in separate tests to clearly identify processing deficits.
  • It is extensively normed for both children and adults (ages 4 to 80+)
  • It precisely measures reaction times (±1 ms)
  • It is language and culture free.
  • It promotes efficient and effective communication with parents and schools by means of the Home and School Success Strategies.
  • The T.O.V.A. 8 can run on the following operating systems:


    -Windows XP (32-bit, SP2 or better)

    -Windows Vista (all versions)

    -Windows 7 (all versions)

    -The T.O.V.A. 8 is not compatible with most Windows 8 systems--click here for details.
