ISA – International
Symbol of Access
In 1968 members of RI
and ICTA were asked to consider establishment of an international
symbol to designate accessible facilities. Six symbols were short
listed and considered by a representative jury of people with
disabilities and international organisations.
The symbol designed by a Danish student Susanne Kofoed was selected,
and after minor modifications was adopted by RI and ICTA in 1969
as the International Symbol of Access (ISA).
International Symbol of Access (ISA)
The ISA has been registered with the International Standards Organisation
(ISO) and remains the copyright of ICTA. Guidelines
for Improving Access for People with Disabilities,
setting our planning guidelines for use of the ISA were published
by RADAR UK in 1983.
The ISA provides a consistent international designation of accessible
entrances, information, facilities, transportation and amenities.
Other symbols to assist people with sensory impairments, including
the International Symbol for Deafness
may be used in conjunction with the ISA.
