My students see an error message when they sign in to take the SAT School Day or a PSAT-related assessment. What should I do?

If your students enter the correct credentials from their sign-in ticket but see the error message “Your user ID or registration number is wrong. Please check your sign-in ticket and try again,” a network issue could be the cause.

Security appliances and software can prevent some or all students from signing in. Make sure your network is configured to support Bluebook testing.
