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. The following states/territories have laws prohibiting discrimination in schools on the basis of gender identity: Washington, Oregon, California, Nevada, Colorado, New Mexico, Minnesota, Iowa, Illinois, Michigan, Virginia, District of Columbia, Maryland, Hawaii, New Jersey, New York, Connecticut, Vermont, New Hampshire, Maine, Massachusetts, and Puerto Rico. North Dakota and Pennsylvania have interpreted such a provision into their existing laws, and Utah has school code / regulatory protections. The following states have laws prohibiting bullying on the basis of gender identity: Washington, California, Oregon, Nevada, Colorado, New Mexico, Minnesota, Iowa, Illinois, Arkansas, North Carolina, District of Columbia, Maryland, Delaware, New Jersey, Connecticut, Rhode Island, Massachusetts, New York, New Hampshire, and Maine. Utah and West Virginia prohibit the same through school regulations.
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”.
