The investigation is the process by which the school collects evidence. An investigator may be employed by the school or a third-party (typically a lawyer) hired by the school. A school may assign multiple investigators to a case, depending upon the complexity of the matter. The investigative process should be fair and equitable, which means that any opportunity a school offers to one party, it must offer to the other. During the investigation, an investigator meets with the complainant, respondent, and witnesses to gather evidence.
