The Dyslexia Screener

This screener is normed for grades 2 through 8. With prevalence of dyslexia ranging from 10% to 20% in elementary and middle schools, it is imperative to detect it and make appropriate referrals for further testing and diagnostic evaluation of dyslexia. TDS screening has high sensitivity and specificity for detecting dyseidetic (visual) and dysphonetic (auditory) types of dyslexia. It is an important tool for professionals on the multidisciplinary team involved in helping individuals with reading problems. These may include teachers, resource educational specialists, school psychologists, speech-language specialists, pediatricians, optometrists, ophthalmologists, occupational therapists, school nurses, and other professionals. They particularly need a dyslexia screening procedure when parents present their children with the complaint that: "My child is having trouble reading."

This test is normed for college grade levels or for examinees over 18 years of age who have completed high school but without college education. The importance of education has been widely disseminated throughout the United States. Adult schools and literacy programs are found in most communities. Because of the high prevalence of dyslexia, even in the adult population, it is necessary to determine the presence and severity of specific eidetic and phonetic coding problems in dyslexic adults. The ADT is the first test, and only one of its kind, to fill this need and allow for recommendations for specialized educational therapy in literacy, occupational therapy, and counseling programs, based on ADT results. The ADT comes with complete instructions, stimulus decoding pages, and recording sheets for decoding and encoding results, allowing for determination of dyslexic types and degrees of severity.
