The Americans with Disabilities Act (ADA) was passed July 26, 1990 as Public Law 101-336 and became effective on January 26, 1992. The ADA is landmark federal legislation that provides civil rights protections to individuals with disabilities.
An individual with a disability and/or medical/mental health condition is defined by the ADA as a person who:
A physical or mental impairment that substantially limits one or more of such person's major life activities
Has a record of such an impairment
Is regarded as having such an impairment
The terminology "substantially limits" refers to a person unable to perform a major life activity that the average person in the general population can perform
A person significantly restricted as to the condition, manner, or duration under which the average person in the general population can perform the same major life activity
