N.C. Gen. Stat. § 115C-416
The Board shall have power to provide for the enrichment and strengthening of educational opportunities for the children of the State, and when sufficient State funds are available to provide first for the allotment of such a number of teachers as to prevent the teacher loan from being too great in any school, the Board is authorized, in its discretion, to make an additional allotment of teaching personnel to local school administrative units of the State to be used either jointly or separately, as the Board may prescribe. Such additional teaching personnel may be used in the local school administrative units as librarians, special teachers, or supervisors of instruction and for other special instructional services such as art, music, physical education, adult education, special education, or industrial arts as may be authorized and approved by the Board. The salary of all such personnel shall be determined in accordance with the State salary schedule adopted by the Board.
In addition, the Board is authorized and empowered in its discretion, to make allotments of funds for clerical assistants for classified principals and for school social workers.
The Board is further authorized, in its discretion, to allot teaching personnel to local school administrative units for experimental programs and purposes.
The Board may also allot teaching and other positions, within funds available, to local school administrative units to allow local units to place personnel occupying those positions in private hospitals and treatment facilities for the limited purpose of providing education to students confined to those institutions. The Board shall adopt rules to ensure that any such placements do not contribute to the profitability of private institutions and that they are otherwise in accordance with State and federal law.
