Many schools follow a similar process for dealing with disciplinary problems – usually by starting with individual teachers and then, if needed, involving more senior school staff, like:
the subject teacher, or perhaps the head of department for that subject
the form teacher
the dean
an assistant principal or deputy principal
the principal.
The school guidance counsellor may also become involved in disciplining a student, but counsellors usually prefer to stay outside the discipline process so that they can provide support for the student.
