N.C. Gen. Stat. § 115C-523
It shall be the duty of every teacher and principal in charge of school buildings to instruct the children in the proper care of public property, and it is their duty to exercise due care in the protection of school property against damage, either by defacement of the walls and doors or any breakage on the part of the pupils, and if they shall fail to exercise a reasonable care in the protection of property during the day, they may be held financially responsible for all such damage, and if the damage is due to carelessness or negligence on the part of the teachers or principal, the superintendent may hold those in charge of the building responsible for the damage, and if it is not repaired before the close of a term, a sufficient amount may be deducted from their final vouchers to repair the damage for which they are responsible.
Notwithstanding any other provision of law, the parents or legal guardians of any minor are liable for any gross negligence or willful damage or destruction of school property by that minor to the extent of five thousand dollars ($5,000). The Board of Education shall make written demand upon the parent or legal guardian as a prerequisite to bringing suit.
It shall be the duty of all principals to report immediately to their respective superintendents any unsanitary condition, damage to school property or needed repair.
