You can register for the SAT online on the College Board site or via mail. For the online option, check out the College Board’s guidelines regarding account creation, photo ID submission, test dates, test center locations, and more. 

To register by mail, you will need to ask your school counselor for a copy of the Student Registration Booklet for the SAT. If you need special accommodations for testing, including requests to test closer to home, you will need to register by mail. If you are ever unsure about your options for registration, ask your school counselor how to sign up for the SAT.
