National Disability Independence Day is celebrated every year on July 26. It commemorates the signing of the Americans with Disability Act (A.D.A.) in 1990. This civil rights law criminalizes any kind of discrimination against individuals with disabilities and assures them full participation in the community, independent living, and economic self-sufficiency. The Americans with Disability Act covers the following areas: public accommodation, employment, transportation, and state and local government services. A.D.A. is a life-changing act for many people. Today, one in four Americans with a disability can access and participate better in their workplaces and general communities.
