Title Ix Report Has Been Brought Against Me

Location: GA

I work as a substitute teacher for public schools, but predominately work at the local high school. Last Friday I was informed that there's been a report of me having a sexual conversation with a student which prompts an immediate Title IX investigation and I cannot work in any public schools while the investigation is on going. This is all the information I have as of now and do not know which student has filed the complaint, which class I was in, or even what was allegedly the content of the conversation. As a sub I am in different classes nearly everyday and I see hundreds of students in a week. So the longer I go without any details the longer I will have to relay on memories of conversations with students many I don't even know the name of...

I know Title IX investigations don't have hearings in k-12 like they do in higher ed, so how do I go about defending myself? I can attest that I have never had any alone time with any students, i've never exposed myself to any students, I've never attempted to contact students outside of the classroom, I've never made sexually suggestive comments or remarks to or about any students. Anyway I can think that Title IX describes as sexual harassment I have not done. Though proving negatives are really hard to do. I have other teachers that could comment on my pattern of professional behavior some have literally heard me say "I legally cannot do that" to students that have crossed a line, but I'm not sure how much weight that would carry if they are not a direct witness.

What really worries me is the burden of proof being only 51% likely of happening, which seems like a really low bar for something so serious. If this comes down to a 'he said she said' or high schoolers spreading rumors I don't know how to adequately defend myself here.

TLDR; Any advice on Title IX procedures in high school settings and or how to go about forming a defense in a case like this. Thanks
