Additional Assessments/Screenings

In addition to the standard reading and math diagnostic assessments available at Success Center, the center now offers three screenings: the Dyslexia Determination Test (DDT); Scotopic Sensitivity Syndrome (SSS); and the Test of Variables of Attention (TOVA).

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.

Success Center is an approved screening site for Scotopic Sensitivity/Irlen Syndrome. Irlen Syndrome is a perceptual problem that prevents an estimated 10-12% of the population from being able to learn, read or study efficiently. Individuals with Irlen perceive the printed page and sometimes their environment differently.

Individuals with Irlen may be viewed as underachievers or as having behavior, attitude or motivational problems. This problem can coexist with other learning difficulties. Some people diagnosed with learning difficulties, dyslexia or ADD may be, in addition, also suffering from Irlen.

The patented Irlen Treatment Method uses precision tinted filters, worn as glasses or coloured overlays, to reduce or eliminate perception difficulties and light sensitivity. An intensive diagnostic assessment determines the beneficial filter colour from an almost limitless number of colour combinations. The assessment takes about one hour and can be used for children and adults.

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 Centerare 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.
