Depends on what you mean by "a school?" The university may release/dismiss a student for violation of student code of conduct. Cheating on an exam or project assignment, plagiarism are academic examples. Pretty sure Ferrari was dismissed from the university mid/late Spring semester, there was a lot going on. Don't know that a university would get involved in violation of team code of conduct for athletes that would be within the team or a DIA level decision. For dismissal there need to be a clear set of rules and a documented violation, prob can't just kick someone out cause they did something bad.
