The Colorado Instructional Materials Center (CIMC) provides braille and large print textbooks as well as instructional aids to students who are blind or visually impaired and are enrolled in Colorado's pre-K - 12 schools. The CIMC maintains an annual registration of Colorado students with visual impairments and registers those students who are legally blind with the American Printing House for the Blind (APH). The CIMC is able to purchase books through funds provided by the Colorado Department of Education, Colorado school districts, and the APH Federal Quota Registry.
