N.C. Gen. Stat. § 93-12.2: Board records are confidential.

Records, papers, and other documents containing information collected or compiled by the Board, its members, or employees, as a result of a complaint, investigation, inquiry, or interview in connection with an application for examination, certification, or registration, or in connection with a certificate holder's professional ethics and conduct, shall not be considered public records within the meaning of Chapter 132 of the General Statutes. Any notice or statement of charges against a certificate holder or applicant, or any notice to a certificate holder or applicant of a hearing to be held by the Board is a public record, even though it may contain information collected and compiled as a result of a complaint, investigation, inquiry, or interview conducted by the Board. If any record, paper, or other document containing information collected and compiled by the Board is admitted into evidence in a hearing held by the Board, it shall then be a public record within the meaning of Chapter 132 of the General Statutes.
