Which statement correctly describes the ADA standard scope?

• A. ADA standards only cover signage.
• B. ADA Standards for Accessible Design cover accessibility requirements for built environments and services.
• C. ADA standards only apply to exterior design.
• D. ADA standards are unrelated to barrier-free design.

Answer: (B)

The main idea is that the ADA Standards for Accessible Design set accessibility requirements for both the built environment and the services offered in those environments. This means they cover interior and exterior features—things like accessible routes, entrances, doors, restrooms, parking, and signage—as well as how programs and services are delivered (for example, accessible counters, effective communication, and staff assistance). The goal is to ensure barrier-free access for people with disabilities across all aspects of using a facility, not just one element like signage or exterior design. So the statement that describes accessibility requirements for built environments and services best captures the scope.
