Preferred Name Fiasco

I am 41 with a BS and an AS. I am in school for a certificate and for the first time ever have an instructor who refused my preferred name and insists on the name on the roster.

Now, I'm cis and my preferred name is just my middle name - I have gone by it and that's never been an issue. I never legally removed my first name because I don't hate it and again it's never been an issue.

If it were as simple as him misremembering, no big deal. If he never called us by name, also no big deal. But he does call us by name to answer questions. Personally, I assume it is part of his general rudeness and distancing himself from students. I am however tempted to bring it to the college's attention - someday someone will be deadnamed and have to fight with him. Universities in this area have preferred name policies to address exactly this.

Curious how academia is viewing this issue, and thoughts on taking any action.

You've mentioned that you've asked multiple times that he use your preferred name. Have you asked in writing (via email)? If not, do so. Forward the instructor's response to the chair of the department along with a brief explanation that you've asked multiple times verbally & now in writing and the instructor continues to ignore your request. 

Often, a policy at the institution level isn't developed until an individual situation brings the issue to the attention of administration.
