Additional Assessments

In addition to the standard reading and math diagnostic assessments available at Success Center, the center offers two screenings: the Dyslexia Determination Test (DDT) and the Test of Variables of Attention (TOVA).

Dyslexia Determination Test (DDT)

Dyslexia pertains to language disabilities. The Dyslexia Determination Test (DDT) is used to investigate specific aspects of language problems relating to reading, writing and spelling. The DDT differentiates the child who demonstrates dyslexic tendencies from the individual who is merely behind in reading, writing and spelling due to causes other than a dyslexic pattern as defined and determined by this testing procedure. A child must be reading (at least) at a second grade level for the test to be valid.  

Test of Variables of Attention (TOVA)

The Test of Variables of Attention (TOVA) is a computerized visual continuous performance test for the diagnosis and treatment of children and adults with attention disorders; off-task behaviors; Attention Deficit Disorders (ADD); and Attention-Deficit Hyperactivity Disorder (ADHD). This highly reliable test provides relevant screening information about attention that is not otherwise available.

Results of all assessments and screenings at Success Center are confidential. However, results can be shared with the child's teacher in a school visit if the parent wishes. For more information, call Success Center at (903) 737-2900.
