If a person knows Sign Language can, they sign the information to a Deaf individual?
Interpreting is a very complex task that requires more than just knowing some Sign Language. The process of translating a message from one language to another requires a high level of proficiency in both languages. A co-worker, or someone who is responsible for other duties in your workplace, should not be put in the position of interpreting for a Deaf colleague or customer. Signing for their peer takes away from his/her ability to perform his/her assigned duties. Additionally, there is no guarantee of quality, accuracy, or confidentiality of information when not using a certified interpreter. In many cases, more damage has been done by a “signer” who is trying to help out, requiring more extensive interpreting time to repair the misunderstandings caused by not using an interpreter the first time.
