It will depend on the given school in question. Different schools are going to have different policies as to how sanctions are assigned. If a student is found responsible for sexual misconduct under the school's sexual misconduct policy, different schools will have, again, different policies as to how sanctions would be imposed. Schools in terms of best practices should take into account the nature of the allegation, how severe the act was. They should take into account how it impacted the complainant, also how it impacted the respondent. It can obviously affect both parties, the respondent's disciplinary history, the respondent's, say, involvement with the school, even grades, for example, can be a consideration in sanctioning.
In large part though, the sanction itself would be most commensurate with the act itself, the severity of the act in terms of the actual sanction. It could be, say, administrators at the school, sometimes even students are involved in sanctioning depending on the given school. It does vary, an experienced attorney advisor can help you best understand if you're at the point in the case where sanctions may be imposed, or even well before that, hopefully, so that you could try to avoid such a unfortunate result obviously. An experienced attorney advisor can help do everything within his power to try to ensure a fair process and a favorable outcome ultimately.
