* Inappropriate behavior. This can include anything from public displays of affection to sexual harassment.
* Under the influence of drugs or alcohol. Showing up to a school dance intoxicated is a surefire way to get kicked out.
* Dress code violations. Some school dances have dress codes, and students who violate these codes may be asked to leave.
* Refusing to follow instructions from school staff. If a student is asked to leave the dance by a school staff member, they should do so immediately. Failure to comply can result in further disciplinary action.
