A simple e-mail explaining your situation to professors or classmates could make transitioning much easier. E-mails can be useful in explaining your situation to professors who previously knew you by a different name. They can also be useful in informing professors that you go by a different name and gender than the one they have on the class roster.
I am a student in your _____ class this quarter; however, before class begins, I wanted to inform you of a change that is taking place in my life.
I identify as transgender, which, for me, means that I was born female, but I feel much more comfortable presenting myself as a man. This summer, I began a process to change my gender. It is something that I have been thinking about doing for a very long time, and I am much happier now that I have begun this process. I have almost completed a legal name change, and I am going through some gradual physical changes. I am changing my name legally from __________ to ___________ the first week of classes, and class rosters should reflect this change soon.
I wanted you to be informed of this change before class started. I would appreciate it if you could refer to me by male pronouns in your class and use the name of ______ instead of___________.
If you have any questions for me regarding this change or anything else, please don't hesitate to contact me either in person or through e-mail. My e-mail address is __________, and my phone number is _________.
