N.C. Gen. Stat. § 90D-2

The practice of manual or oral interpreting and transliterating services affects the public health, safety, and welfare, and therefore the licensure of these practices is necessary to ensure minimum standards of competency and to provide the public with safe and accurate manual or oral interpreting or transliterating services. It is the purpose of this Chapter to provide for the regulation of persons offering manual or oral interpreting or transliterating services to individuals who are deaf, hard-of-hearing, or dependent on the use of manual modes of communication in this State.
