The Title IX Final Rule emphasized the Title IX coordinator being made known to anyone and everyone at a school because the Title IX Final Rule has limited the mandated scope of mandatory reporters, has made it the case where say all college and university employees do not have to be mandatory reporters.
It's up to a school's discretion in that regard. A school can allow for confidential resources, in other words, so complaints that would have otherwise made it to the Title IX coordinator to be pursued, it may no longer be the case unless somebody files a formal complaint. The Title IX Final Rule basically has emphasized the fact that the Title IX coordinators' contact information has to be made widely available to students, applicants for applicants to the school, applicants for employment at the school.
That is a significant aspect of how a Title IX coordinator's role or the obligation in a school would have with respect to a Title IX coordinator have changed under the Title IX Final Rule.
