Mara,
I’ve just set this up for you. (For those of you who would like to do the same, there is a Gender Code Set where you can define additional values.)
Please note that if you change Gender from M/F, you will need to have a M/F populated in the Legal Gender field. AK State reporting does not currently recognize any gender values besides M/F. Additionally, I configured the Gender Pronouns to return they/them/their
in form letters/places you use the pronoun data access tag. (District Management -> People - > Gender Pronouns)
Additionally, on future Civil Rights Data Collections (a federal report), you will need to indicate that you collect information about non-gender students.
