The TOVA Company

The TOVA Company manufactures and distributes the T.O.V.A. 9 (Test of Variables of Attention), a FDA-cleared medical device for objective assessment and evaluation of attention deficits, including ADHD, across clinical, educational, and research settings. The T.O.V.A. 9 measures key variables of attention and inhibitory control through standardized computerized testing with millisecond-level timing accuracy. The device is normed for ages 4–80+ and offers both visual and auditory test formats to measure separate functions independently. It includes an embedded performance validity measure for persons 17 and older and a short test option for preschool-aged children. The platform provides clinicians with objective data on response time, response time variability, and attentional performance that is not available from clinical interviews or behavioral rating scales alone. The T.O.V.A. 9 is supported by over 300 peer-reviewed publications demonstrating correlation between T.O.V.A. variables and ADHD diagnosis. Regulatory clearances include US FDA 510(k), European MDD, Health Canada MDEL, and Australian TGA. The company holds ISO 13485:2016 certification under MDSAP. The TOVA Company provides comprehensive support including free technical support, interpretation support, and customer service. The company operates a referral network and conducts monthly educational webinars for providers.
