A student ID is a unique set of characters assigned to each student within a school district. If you are a student trying to register an account and you receive an error that your student ID is already in use, please contact your school’s District Administrator to confirm that you have the correct student ID. If your student ID is correct and is already tied to an account under your name, we recommend using that account.
Students who previously self-registered should keep their credentials every year they use the Big Ideas Math program. Each year, students should log in with their credentials at BigIdeasMath.com, click on their name at the top of the website, and then click Add Class. Students should enter the new class access code provided by their teacher. Registering for new classes in this manner will ensure the accessibility of students' data from previous years.
