For over 30 years of teaching I had the students fill out an info card … one of the questions was how did they want to be addressed or called … for example Micheal wanted to be called Mike, or Rebeca wanted to be called Becky … it really wasn’t a big deal … so OK the last few years I had a student or two who identified as a male … for example, Michelle who wanted to be called Micheal .. still not a real big deal to me … I am not sure why this is an issue.
PS … Our school had a policy that students still were to go into their biological bathroom, if they didn’t feel comfortable with that they could go into the restroom in the main office … once again, not making it a major issue out of it.
