Dr. David P. Hurford is a research scientist who has studied dyslexia for the past three decades. From this work, he established the Center for the Assessment and Remediation of Reading Difficulties (CARRD), a nonprofit dedicated to assisting individuals with dyslexia to become competent readers. Dr. Hurford's mission involves the prevention and remediation of reading disabilities, searching for strategies that will lead to the improvement of remedial processes, and providing educators and parents with intervention techniques regarding reading and learning disabilities. CARRD has developed procedures to identify young children who may be at risk for reading difficulties, dyslexia, and Attention Deficit Hyperactivity Disorder (ADHD). Just as important, CARRD developed training procedures to help children become competent readers. To prevent future reading difficulties, Dr. Hurford used his knowledge of learning and reading disorders to write Secret Codes, a reading curriculum for kindergartners. The curriculum was based on the Science of Reading and was created to teach reading to all children, but was designed especially to prevent reading failure in students at-risk for reading failure.
