It has come to the Department of Education's (ED's) attention that many transgender students (i.e., students whose gender identity is different from the sex they were assigned at birth) report feeling unsafe and experiencing verbal and physical harassment or assault in school, and that these students may perform worse academically when they are harassed. School administrators, educators, students, and parents are asking questions about how to support transgender students and have requested clarity from ED. In response, ED developed two documents: (1) A Dear Colleague Letter about transgender students' rights and schools' legal obligations under Title IX of the Education Amendments of 1972; and (2) ED's Office of Elementary and Secondary Education compiled the attached examples of policies and emerging practices that some schools are already using to support transgender students. This guide shares some common questions on topics such as school records, privacy, and terminology, and then explains how some state and school district policies have answered these questions. This guide presents this information to illustrate how states and school districts are supporting transgender students. Also provided are information about and links to those policies at the end of the document, along with other resources that may be helpful as educators develop policies and practices for their own schools.
