The advice on the subject of informing parents reads:
Telling parents
Note that the ACLU is very protective of a student’s right to privacy in his/her sexuality. If a school employee believes that “a situation exists which presents a serious threat to the well-being of a student,” the employee must notify parents without delay. (Utah Code 53A- 13-302(6)(b)(i)). Other than a threatening situation, volunteering known information about a student’s sexuality with parents is not advised.
Consider the following factors in making a determination about talking to parents:
Age of students
Whether student is being bullied based on sexuality or gender identity
Student requests
Knowledge of parents’ relationship with students
What if a student asks to be called a preferred name/pronoun and parents object? Unless the student is 18, parents’ requests should govern.

Seems pretty reasonable to me.
