Telecommunications Relay Service provides full telephone accessibility to people who are deaf, hard of hearing, deaf-blind, or speech-disabled. Specially trained Communication Assistants (CAs) serve as intermediaries, relaying conversations between hearing persons and persons using a text telephone device (TTY). Relay Service is available 24 hours a day, 365 days a year, with no restrictions on the length or number of calls placed. This valuable communications tool gives all individuals the opportunity to make personal and business calls just like any other telephone user. The relay service makes it possible for teachers in postsecondary settings to notify deaf, hard of hearing, deaf-blind, or speech-disabled students of any class changes or cancellations. These students can also use the service to contact instructors when necessary. This paper provides tips for using the Telecommunications Relay Service.
