Per University of California (UCOP) policy, UC San Diego is required to retain a history of your violation for five (5) years after the end of the academic year in which your case was closed (a.k.a. the decision was made). For example, if your case was resolved in Winter 2020, the record will be retained until the fall of 2025. There is one exception to this - if you were assigned a dismissal, the records (for all violations) are retained for fifty (50) years.
A warning is not reported out to graduate/ professional schools/employers unless you have been found responsible for a subsequent violation.
Your disciplinary record is confidential and protected by the Family Education Rights to Privacy Act (FERPA). Your disciplinary record is not visible to individuals, whether employed at UC San Diego or not, unless they have a legitimate educational need to know.
In most instances, no, your disciplinary record will not appear on a standard background check. However, in rare instances some employers may conduct higher level security and background checks. If this occurs, the party conducting the background check would need to inform you that they will be collecting your disciplinary records.
No, once the disciplinary action has been issued, it cannot be altered (except possibly upon appeal for Suspensions or Dismissals).
Disciplinary Probation is a status imposed until graduation during which you must demonstrate integrity. Further violations during the probationary period may result in further disciplinary action, normally in the form of Suspension or Dismissal.
