The Northwest Center for Assistive Technology Training (CATT) Program is a collaboration between the American Printing House for the Blind (APH) and the Washington State School for the Blind (WSSB). Our mission is to provide assistive technology training to teachers of blind/low vision children, utilizing a "train the trainer" model, while also providing support/training for other professionals working with blind or low vision children as well as parents/caregivers of a child who is blind or has low vision, including those with additional disabilities.
