G.S. 143-318.9 through G.S. 143-318.18

County social services boards are subject to the state’s open meetings law.
A social services board may meet in closed session (that is, a portion of the board’s meeting from which the public is excluded) when the closed session is:
required to prevent the disclosure of information that is confidential or privileged under federal or state law;
required to preserve the attorney-client privilege with respect to communications between the board and the board’s attorney;
required to consider the qualifications, competence, performance, fitness, conditions of appointment or initial employment of an individual public officer or employee or prospective public officer or employee or to hear or investigate a complaint, charge, or grievance by an individual public officer or employee; or
authorized by other provisions in the state’s open meetings law. 
The board may not consider general issues regarding agency personnel or policies or the qualifications, competence, performance, character, fitness, appointment, or removal of social services board members or members of other public bodies during a closed session. 
The board, acting through the social services director as its secretary, must keep full and accurate minutes of all official board meetings (including closed sessions of board meetings) and a general account of all closed sessions. Minutes and general accounts of closed sessions may be withheld from public inspection for so long as public inspection would frustrate the purpose of the closed session.
