Two-thirds of U.S. public school districts have schools with physical barriers that
may limit access for people with disabilities, according to GAO’s survey of district
officials. Barriers, such as a lack of accessible door hardware and steep ramps,
can make it challenging for students, teachers, and others with disabilities to use
public school facilities (see fig.). In 55 schools across six states, the most
common areas with barriers GAO observed were restrooms, interior doorways,
and classrooms. GAO also observed barriers related to safety and security. For
example, for security, some schools had installed double-door vestibules with
limited maneuvering space that could trap people who use wheelchairs.
