(c) The teacher may exclude from his or her classroom or school bus any student who is guilty of disorderly conduct; who in any manner interferes with an orderly educational process; who threatens, abuses or otherwise intimidates or attempts to intimidate a school employee or a student; who willfully disobeys a school employee; or who uses abusive or profane language directed at a school employee. Any student excluded shall be placed under the control of the principal of the school or a designee. The excluded student may be admitted to the classroom or school bus only when the principal, or a designee, provides written certification to the teacher that the student may be readmitted and specifies the specific type of disciplinary action, if any, that was taken. If the principal finds that disciplinary action is warranted, he or she shall provide written and, if possible, telephonic notice of the action to the parent(s), guardian(s) or custodian(s). When a student is excluded from a classroom or a school bus two times in one semester, and after exhausting all reasonable methods of classroom discipline provided in the school discipline plan, the student may be readmitted to the classroom or the school bus only after the principal, teacher and, if possible, the parent(s), guardian(s) or custodian(s) of the student have held a conference to discuss the student's disruptive behavior patterns, and the teacher and the principal agree on a course of discipline for the student and inform the parent(s), guardian(s) or custodian(s) of the course of action. Thereafter, if the student's disruptive behavior persists, upon the teacher's request, the principal may, to the extent feasible, transfer the student to another setting. The Legislature finds that isolating students or placing them in alternative learning centers may be the best setting for chronically disruptive students. The county board shall create more alternative learning centers or expand its capacity for alternative placements, subject to funding, to correct these students' behaviors so they can return to a regular classroom without engaging in further disruptive behavior.
