The Test of Variables of Attention, commonly known as the T.O.V.A., is a standardized, computerized neuropsychological test that provides an objective measure of a person’s attention and inhibitory control. It has been used in clinical practice and research for decades and is recognized as one of the most scientifically validated attention assessments available.
Unlike questionnaires or symptom checklists, which rely on self-reporting or caregiver perception, the T.O.V.A. directly measures how the brain performs during a sustained attention task. It is culture-free, language-free, and does not require reading, making it accessible across a broad range of ages and backgrounds.
Results are compared against a large, age- and gender-matched normative database, as well as a population of individuals independently diagnosed with ADHD. This dual comparison gives clinicians a powerful, objective data point to inform assessment and treatment planning.
💡 T.O.V.A. stands for Test of Variables of Attention, a clinically validated, computerized assessment that objectively measures key aspects of attention and inhibitory control.
How consistent are responses? Measures "micro-attention" whether the brain drifts between stimuli.
Average speed of correct responses. Reflects information processing speed, too fast or too slow both carry clinical meaning.
Responding to the wrong target. Measures impulsivity and inhibitory control, a key factor in decision-making.
Missing the correct target. Measures focus, sustained attention, and distractibility.
If prior ADHD testing felt incomplete or you want an objective measure to complement an existing diagnosis, T.O.V.A. provides a data-driven picture that goes beyond observation.
Adults and children experiencing unexplained difficulties concentrating, completing tasks, or managing distractions can use T.O.V.A. results to better understand what's happening neurologically.
If you or your child are undergoing an ADHD evaluation, T.O.V.A. results add objective neurological data to complement clinical interviews and behavioral questionnaires.
T.O.V.A. testing can be administered before and after starting or adjusting a medication to measure objective changes in attention and impulsivity. It takes the guesswork out of treatment adjustments.
The T.O.V.A. is validated for a wide age range. A shorter version is administered to children ages 4–5.5, and standard testing is available for school-age children through adults.
T.O.V.A. can help assess attention deficits related to traumatic brain injury (TBI), sleep disorders, anxiety, depression, post-traumatic stress disorder and other conditions that affect cognitive performance.
Book a T.O.V.A. testing appointment at our Central Point, Oregon office. No referral is required, you can book directly as a patient or caregiver. We'll confirm your appointment and send any required intake paperwork.
Come to your appointment feeling rested and, if applicable, without taking any stimulant medications that morning (unless instructed otherwise by your provider). Let our staff know if you are testing on or off medication — both are clinically useful.
Our clinician or trained staff will explain the test procedure clearly before you begin. You'll be seated at a computer and given a small handheld microswitch button. The task is simple: respond when you see (or hear) the target stimulus, and don't respond when you see the non-target.
The visual test presents two simple geometric images on screen; the auditory test uses two tones. You respond using the microswitch. The test captures response data with ±1 millisecond precision over the full session — this precision is what makes it clinically meaningful. A shorter version (~11 minutes) is used for children ages 4–5.5.
After completion, your responses are automatically scored and compared to age- and gender-matched normative data, as well as to a population of individuals diagnosed with ADHD. This dual comparison generates an immediately available, easy-to-read report.
Your T.O.V.A. results will be reviewed and interpreted by a qualified Care Anywhere clinician. Remember: T.O.V.A. results are not a diagnosis on their own. Only a licensed clinician can diagnose ADHD or any other condition. The results are one important piece of the clinical picture.
Unlike questionnaires, T.O.V.A. results reflect actual neurological performance — not how someone describes their symptoms. This eliminates bias and provides a clearer clinical picture.
The T.O.V.A. has correctly identified 87% of non-ADHD and 90% of ADHD subjects in clinical research. It is one of the most extensively studied attention tests in use today.
Two people can share the same ADHD diagnosis but have very different attentional profiles. T.O.V.A. captures the nuances including whether challenges involve focus, impulsivity, speed, or consistency.
T.O.V.A. testing before and after medication changes provides objective evidence of whether treatment is working, helping providers make informed and confident decisions.
Because the test uses geometric shapes and tones not words or numbers, it is equally accessible to patients of any language background, reading level, or cultural context.
Completing in approximately 21 minutes with no preparation required, T.O.V.A. is a fast, comfortable, and efficient way to gather meaningful clinical data about attentional functioning.
You don’t need to be an existing patient or book a full psychiatric evaluation to access T.O.V.A. testing at Care Anywhere Psychiatry. We offer this test as a standalone, à la carte service at our Central Point, Oregon location.
Whether you’re preparing for an ADHD evaluation, tracking the effect of a medication change, or simply want objective data about your attention, you can schedule a T.O.V.A. test appointment on its own.

Plan for approximately 45–60 minutes total, including arrival, instructions, the test itself (~21 minutes), and a brief review of results. Children ages 4–5.5 will take a shorter 10.8-minute version of the test.
Try to get a normal night of sleep before your test. Significant fatigue or sleep deprivation can affect attention performance and may influence test results. Avoid caffeine in large amounts if possible.
T.O.V.A. results will be reviewed by a Care Anywhere clinician. It's important to understand that the T.O.V.A. alone cannot diagnose ADHD or any other condition — it provides objective data that must be interpreted by a qualified professional within a broader clinical context.
Bring a valid photo ID and any relevant medical records (prior evaluations, diagnoses, or medication lists). If a minor is being tested, a parent or legal guardian must be present to provide consent.
If you have a separate treating clinician or are using T.O.V.A. data to support an evaluation elsewhere, we can provide your results in a format suitable for sharing. Please let us know at booking so we can prepare accordingly.
Whether you take the test on or off your current medication is a clinical decision. Testing both ways (once on medication, once off) can provide valuable comparison data. Your clinician or referring provider can advise which approach is best for your situation.
No. The T.O.V.A. cannot diagnose ADHD — and no single test can. Only a licensed clinician can make a diagnosis, which requires integrating multiple sources of information including clinical history, behavioral observations, and assessment results. What T.O.V.A. provides is high-quality, objective attention data that contributes meaningfully to that diagnostic process.
No. T.O.V.A. testing is offered as a standalone, à la carte service. You do not need to be an established patient of our practice to schedule a T.O.V.A. test appointment. However, if you are interested in a full psychiatric evaluation, we’d be happy to discuss that option with you as well.
No. The T.O.V.A. requires specialized hardware (a precise microswitch and the T.O.V.A. device) and must be administered in person by trained clinical staff to ensure accuracy and validity. T.O.V.A. testing is only available at our Central Point, Oregon office.
T.O.V.A. testing at Care Anywhere Psychiatry is currently offered as a self-pay service at $175 per test. Some insurance plans may provide partial out-of-network reimbursement for neuropsychological testing. We recommend contacting your insurer to check your out-of-network benefits. We can provide a superbill or documentation of services upon request.
The T.O.V.A. is validated for ages 4 and up. Children ages 4 to 5.5 take a shorter 10.8-minute version of the visual test. Standard visual and auditory testing is available for children ages 5.5 through 17, and the adult version is available for those 18 and older through age 80+.
T.O.V.A. results are generated immediately after the test is completed. Our clinician will review and interpret the results with you during or shortly after your appointment. Unlike other assessments that can take weeks to process, the T.O.V.A. turnaround is same-day.
This depends on your clinical goal. If you want a baseline measure of your attention without medication, you would test unmedicated. If you want to see how your current medication is affecting your attention, you would test while medicated. Many patients benefit from testing both ways over time. Discuss the best approach with your prescribing provider before your appointment — our staff can also help guide you.
Take the guesswork out of attention assessment. Book a T.O.V.A. testing appointment at our Central Point, Oregon office for $175 — no referral needed, no full evaluation required.
