In the state of Washington, October is a statutorily designated civic holiday called Disability History Month. The bill establishing the holiday passed the state legislature in 2008 and is codified in Title 28A of the Revised Code of Washington in 2008. In addition to the ceremonial designation, the law also requires that "each public school shall conduct or promote educational activities that provide instruction, awareness, and understanding of disability history and people with disabilities".
The 82nd Texas Legislature statutorily designated October as a recurring, month-long civic holiday called "Persons with Disabilities History and Awareness Month" to "encourage public schools and state agencies to celebrate the accomplishments of people with disabilities, highlighting the achievements of Texans with disabilities who made significant contributions to the state and the extraordinary Americans who led the way in the disability rights movement".
