24 Pa. Stat. § 17-1707
The boards of school directors, establishing any joint school or department, may supervise and direct its affairs, jointly, in the same manner as the affairs of individual school districts are managed; or they may agree that the affairs of such joint school or department may be managed by a joint school committee within the limits of the budget adopted by the joint board. Where such management is delegated to a joint school committee, every school board establishing joint schools or departments shall, at the annual meeting during the month of December, select one or more of its members who, with the members chosen in like manner in the other districts, shall constitute the joint school committee. Every such school board may also select at any annual or regular meeting one or more alternates from its members to serve in the event selected members are unable to attend a meeting of the joint school committee. The alternate, when directed by the president of the school board to attend a meeting of the joint school committee in the absence of the selected member, shall have all the powers and duties of a regular member of such committee. This committee shall have all the powers and duties and be subject to all the liabilities with reference to the supervision, maintenance and regulation of such joint schools or departments as are now conferred or imposed by law upon school boards generally. The affirmative vote of a majority of all the members of this committee, duly recorded, showing how each member voted, shall be required in order to take action upon those subjects enumerated in section five hundred eight of this act. Such votes may be recorded in a joint meeting or by mail ballot. Failure to comply with the provisions of this act shall render void and unenforceable the acts of the joint school committee with reference thereto. The joint board and the joint school committee, if authorized, shall organize annually during the month of December by electing a president, vice-president and secretary, who shall perform the duties imposed by this act on the president, vice-president and secretary of regular school boards. The secretary so elected shall serve for a term of four years. The expenses of maintaining the joint school or department shall be paid by warrant drawn on the joint board treasurer by the president and secretary of the joint board or the joint school committee.
Whenever two or more boards of school directors, who are at the time members of a joint board operating a joint school or department, join with other boards or school directors in the formation of a joint school committee operating an area career and technical school or technical institute, the joint committee may be formed as may be agreed: Provided, That each joint school or department have at least one member on the joint school committee.
