Dyslexia Screener for Grades 2-9 (TDS) Kit from Good-Lite (Formerly Richmond Products, Inc.)

The Dyslexia Screener series by Drs John Griffin and Howard Walton provides an indication within a few minutes whether or not the patient exhibits one of the basic types of dyslexia. Several reading levels are covered in separate age appropriate sets plus many of the sets are available in Spanish and French. Results have been compared to the Dyslexia Determination Test (DDT) with differences neither statistically nor clinically significant. The test sensitivity is 88% for dyseidesia and 84% for dysphonesia.
