I will note that there is a section on names/pronouns. Personally, I would hope there would be some allowance of understanding for staff members who may sometimes err on this point. Even the best efforts by human beings can fall short when adults fall back onto habits learned decades ago.
There was a Jan. 2016 article in the NY Times about using new pronouns for non-gendered students.

From district Communications:
Nearly half of Seattle Public Schools’ high schools already have gender neutral bathrooms, and another will open its doors next week at Nathan Hale.
At all 98 district schools, non-conforming students are accommodated and provided access to a restroom facility. SPS is proud to have anti-discrimination policies in place. Superintendent Procedure 3210SP.C was adopted in December 2012 to ensure all students feel safe and included.
