(a) Each student, staff member, teacher, and administrator has a right to attend and/or work at a school which is safe and secure, and which is conducive to learning, and which is free from the threat, actual or implied, of physical harm by a disruptive student. A disruptive student is a person who is subject to compulsory school attendance, who exhibits persistent conduct which substantially impedes the ability of other students to learn, or otherwise substantially interferes with the rights stated above, and who has failed to respond to corrective and rehabilitative measures presented by staff, teachers, or administrators.
(b) The school committee, or a school principal as designated by the school committee, may suspend all pupils found guilty of this conduct, or of violation of those school regulations which relate to the rights set forth in subsection (a), or where a student represents a threat to those rights of students, teachers, or administrators, as described in subsection (a). Nothing in this section shall relieve the school committee or school principals from following all procedures required by state and federal law regarding discipline of students with disabilities.
