(a) To establish and maintain a parent-teacher advisory committee to develop with the school board or governing body of a charter school policy guidelines on pupil discipline, including school searches and bullying prevention as set forth in Section 27-23.7 of this Code [105 ILCS 5/27-23.7]. School authorities shall furnish a copy of the policy to the parents or guardian of each pupil within 15 days after the beginning of the school year, or within 15 days after starting classes for a pupil who transfers into the district during the school year, and the school board or governing body of a charter school shall require that a school inform its pupils of the contents of the policy. School boards and the governing bodies of charter schools, along with the parent-teacher advisory committee, must annually review their pupil discipline policies, the implementation of those policies, and any other factors related to the safety of their schools, pupils, and staff.
