Here are some online documents on the topic of literacy for persons with intellectual / developmental disabilities:

This project examined existing literacy outcomes, conducted a literature search, and held focus groups with front-line literacy practitioners, adult learners and developmental workers and counsellors. The central purpose was to identify ways in which the “Demonstrations of the Learning Outcomes” could best enhance success for adults with developmental disabilities in literacy programs. Meanwhile, a major theme of the project was to maintain the integrity of literacy programs and to ensure successful literacy opportunities for adult learners’ individual growth and progress. This document presents sample Demonstrations. It reports the results of the “Demonstrations of the Learning Outcomes” to organisations and individuals representing the fields of literacy and developmental disabilities.
