Anyone can report sex discrimination, sexual harassment, sexual misconduct, under the Title IX Final Rule. For example, in the college and university setting, it does not need to be the student, him or herself, who's experiencing the sex discrimination or sexual harassment. It can be a parent, it can be a guardian. It could be anybody, otherwise, say associated with the student. In the K-12 setting, the same would apply.
The Title IX Final Rule has expanded the scope of who can report a Title IX complaint and it can also be done in various methods, say, in-person, via email, by mail, by phone. That's a significant aspect of the Title IX rule, the fact that anyone can report the sex discrimination. Having an experienced attorney advisor in one's corner if you're facing a Title IX concern or Title IX case, will help you navigate the process. They'll help allow or work towards a fair process and a favorable outcome. They should be involved in the process from as early as possible.
