  • AFB has a checklist that has been formulated as a tool for reviewing a state or local district's current system of providing accessible textbooks and instructional materials to students who are blind or visually impaired. It is not a survey but a self-assessment tool to determine issues that need to be addressed in order to improve services to students. It can also be used to create a model profile of efficient systems that could be used as states and local districts begin implementing components of the Individuals with Disabilities Education Improvement Act of 2004 (IDEA), P.L. 108-446, regarding production and delivery of accessible textbooks and instructional materials.
