Many Deaf, Deafblind, Deafened and Hard of Hearing individuals are fluent in American Sign Language (ASL) or use some mode of signing. Sign Language Interpreters are professionally trained people who provide a vital link between Deaf, Deafblind, Deafened and Hard of Hearing individuals who use Sign Language as their primary mode of communication and those who do not know Sign Language.

A Sign Language Interpreter may be used any time communication is occurring between people who do not share a common language. Some simple types of communications (for example, between a Deaf customer and a store clerk) can be done through written notes or gestures, but when important content is being communicated (for example, at a job interview), having an interpreter present safeguards the participants by ensuring that information is accessible to both parties.

In order to assist the interpreter with an appointment:

• Any materials, speeches, lesson plans, textbooks, etc. should be supplied to interpreter prior to the assignment.
• Always speak, ask questions, and maintain eye contact with Deaf, Deafblind, Deafened or Hard of Hearing person, not the interpreter.
• Speak at a normal pace. If there is any problem with the speed or in understanding some particular segment or terminology, the interpreter or the Deaf, Deafblind, Deafened or Hard of Hearing person will let you know.
• Everything that is interpreted is kept strictly confidential by the interpreter and will not be discussed with any unrelated parties.
• Because of the mental and physical demands of Sign language interpreting, the presenter should be cognizant that the interpreter may need rest periods.
• For assignments over two hours long, two interpreters will be assigned. Each interpreter will still remain present to provide support to the other even when one is in the "off" position.

While on assignment, interpreters will not participate, make comments, add or edit anything that is being presented by either party. If you wish to have further information about the interpreting process, profession and other related matters, the interpreter may agree to meet/present at convenient time when not on assignment. Questions about the Deaf, Deafblind, Deafened and Hard of Hearing Community are best directed to the person.
