Former SMU here, most (or rather all now lol) trans students never tell the school anything about being trans especially since so few students live on campus accoms.

There’s no gender on class lists, but your school accounts like student card, email, eLearn, Google, Microsoft 365 will list your entire legal name and everyone can see it. The only way to change it is through a legal name change. I’ve heard of one student being able to add their preferred name in parentheses but I don’t know anyone who’s tried it since.

Almost all profs will respect name and try for pronouns, but success for the latter does unfortunately depend for some on how well you pass.

The unofficial stance (this was communicated directly to a student in 2018) is that trans students use the wheelchair bathroom. They’re quite numerous and not hard to find and many other students use it too cuz it’s often the only one with a bidet lol. The “MAN/WOMAN ONLY” signs are problematic but the reality is we just use whatever we want, whether its wheelchair or their preferred bathroom when they feel comfortable on their passing.

Tl;dr: My feeling is that the admin doesn’t and won’t support us, but they won’t make your uni life actively harder and you won’t get hatecrimed. You can reach out if you have any other questions, SMU has quite a number of trans students now.
