This guide pulls together resources on how to support trans students in a high school environment. There are sections for local and national laws protecting trans students, sample policies, and concrete suggestions for ways teachers, advisors, and administrators can support trans youth at our school. The last tab offers suggestions for further research and a list of the books in our library related to trans topics. Supportive adults make a crucial difference in the mental and physical health of trans youth. At Northfield Mount Hermon, we have an especially vital roll to play in supporting boarding students where, in many ways, we are the primary adults in students lives.
