Hello and welcome to Wilson's website! They invite you to learn more about their organization and their extensive work, for almost three decades, dedicated to “Literacy for All.” Teacher knowledge and skill mastery is at the core of their mission, thus Wilson Language Training (WLT) empowers individual educators, schools, and districts to achieve literacy with all students in their care. Initially, WLT's work focused on the education of teachers who were working with individuals with dyslexia. The Wilson Reading System (WRS), and the professional learning certifications associated with it, were developed and established in the 1980s. That work continues today as they help schools and districts develop their own capacity to successfully educate their students with dyslexia. In fact, approximately 25,000 teachers in schools across America have achieved WRS Level I Certification.
