Accessible: Refers to a site, facility, work environment, service, or program that is easy to approach, enter, operate, participate in, and/or use safely and with dignity by a person with a disability.

Accessible Seating: Seating offered by a performance venue of any kind reserved for persons with limited mobility and/or wheelchair users. Accessible seating may also include seating for individuals who are Deaf, in order to provide a line of sight to an American Sign Language (ASL) interpreter.  A venue must not charge a higher price for accessible seating than the cost of the seat an individual requests  (e. g., An individual requesting an accessible balcony level seat must not be charged more than the cost of a balcony level seat ticket, even if the venue’s only accessible seating is located at floor level.)

ADA: (Americans with Disabilities Act) On July 20, 1990, President George H. W.  Bush signed into law the Americans with Disabilities Act. The ADA prohibits discrimination and ensures equal opportunity for persons with disabilities in employment, State and local government services, public accommodations, commercial facilities, and transportation. It also mandates the establishment of TDD/telephone relay services.

ADAAA: (Americans with Disabilities Amendment Act) On September 25, 2008, President George W. Bush signed the Americans with Disabilities Act Amendments Act of 2008 ("ADA Amendments Act" or "Act"). The Act emphasizes that the definition of disability should be construed in favor of broad coverage of individuals to the maximum extent permitted by the terms of the ADA and generally shall not require extensive analysis.

ADA Title I: Title I is the section of the ADA which covers the employment of people with disabilities.  Title I requires employers with 15 or more employees to provide qualified individuals with disabilities an equal opportunity to benefit from the full range of employment-related opportunities available to others. For example, it prohibits discrimination in recruitment, hiring, promotions, training, pay, social activities, and other privileges of employment. It restricts questions that can be asked about an applicant's disability before a job offer is made, and it requires that employers make reasonable accommodation to the known physical or mental limitations of otherwise qualified individuals with disabilities, unless it results in undue hardship.

ADA Title II: Title II is the section of the ADA which covers the access to and participation in state and local government benefits, activities, and services by people with disabilities. It covers all activities of State and local governments regardless of the government entity's size or receipt of Federal funding. Title II requires that State and local governments give people with disabilities an equal opportunity to benefit from all of their programs, services, and activities (e.g. public education, employment, transportation, recreation, health care, social services, courts, voting, and town meetings).

Alteration: Any change to an existing building that affects usability (renovating, remodeling or rearranging walls, structures or parts).

Alternate Means: A means of providing program access to individuals with disabilities when a government building in which a particular program is housed is not accessible; or the program materials are not accessible to all users (e.g., curbside service; service at another accessible location; providing documents in electronic form, instead of requiring the individual to use hard copies).
