Since 2003 it has been a requirement that all schools possess an accessibility plan. These must describe how the school intends to improve access for pupils with disabilities to the curriculum, environment, and information (which includes all written information including signage, handouts, and textbooks). Plans must be in writing and adequately resourced. They must be implemented, reviewed, and revised as necessary. Before drafting their plan, schools are required to consult widely. Plans are renewable every three years and must be published annually.
