The Test of Variables of Attention, or TOVA test, is a computerized exam designed to help determine if a person has some type of attention disorder, like ADD or ADHD. The test is a measure of a person's attention ability, rather than their behavior. It measures attention ability by evaluating responses to certain audio and visual stimuli and then comparing those responses to those of people without an attention disorder who also took the test.
The TOVA test is a very unique, yet simple tool. The exam is designed as a user-friendly computer game that takes around 21 minutes to complete; there is a shorter version available for children between the ages of 4 and 5 which takes just under 11 minutes to complete. The TOVA test involves no language, culture, or left-right discrimination. The test is designed for both children and adults and offers instant results that are easily understandable and accurate - measuring response times down to the millisecond.
Along with the TOVA test, there are a number of other formal tests that can help determine if a person has an attention disorder, including:
Your doctor will decide which ADHD test is best for you or your child. Generally, a test will be administered only after a thorough evaluation has been completed. This is usually the last step in determining if someone is affected by an attention disorder.
