The "Wilson Reading System"[R] is a reading and writing program developed by Barbara Wilson and distributed by Wilson Language Training. It provides a curriculum for teaching reading and spelling to individuals of any age who have difficulty with written language. The program directly teaches the structure of words in the English language, aiming to help students learn the coding system for reading and spelling. The program provides interactive lesson plans and uses a sequential system with extensive controlled text. It is structured to progress from phoneme segmentation to more challenging tasks, and seeks to improve sight word knowledge, fluency, vocabulary, oral expressive language development, and reading comprehension. However, no studies of the "Wilson Reading System"[R] that fall within the scope of the Students with Learning Disabilities review protocol meet What Works Clearinghouse (WWC) evidence standards. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of the program on students with learning disabilities.
