If you go to a public school or college or a private school or college that receives federal funds, a federal law called “Title IX” gives you the right to access equal educational opportunities regardless of sex. The Supreme Court has ruled that discrimination on the basis of sex includes discrimination based on transgender status. Accordingly, your school can't discriminate against you on the basis of your gender identity.
In addition, some states have specific laws protecting trans students. California, Colorado, Connecticut, Hawaii, Illinois, Iowa, Maine, Massachusetts, Michigan, Minnesota, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and Washington D.C. have state laws or policies that prohibit discriminating against students on the basis of gender identity and/or transgender status. Arkansas, California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oregon, Rhode Island, Vermont, Washington, and Washington D.C. have state laws or policies that prohibit bullying based on gender identity. These laws or policies usually apply to all public schools in each state, but some states may also include other types of schools as well.
If you are looking for a resource to give adults at your school guidance about how to make your school safer for trans youth, NCLR has this guide called “Schools in Transition”.
