What is a Suspension? A suspension is a form of school discipline, removing a student from a particular class, or entire school, temporarily. The school may prohibit a student’s attendance from school grounds, a classroom, or place the student in a supervised classroom, separate from other students (“in-school” suspension). When can a Student be Suspended? A school can only suspend a student for behavior specifically outlined in the California Education Code. Unless the behavior is serious, violent, or dangerous to others, the school may only suspend after other interventions have failed. The school may only suspend for conduct related to a school activity or school attendance and cannot suspend a student for school absences or tardies.
