There are only a few things you really need to bring on test day and a lot of things you'll be better off leaving at home. Be sure to bring:
Your up-to-date admission ticket. (You need to print this out.)
Acceptable photo ID
Two No. 2 pencils with erasers
An approved calculator
Epinephrine auto-injectors (like EpiPens) are permitted without the need for accommodations. They must be placed in a clear bag and stored under the student’s desk during testing. For policies on other medications and medical devices, contact Services for Students with Disabilities.
Important: Print Your Admission Ticket
Even if you already printed your admission ticket when you registered, check again to make sure your test center hasn’t changed. Sign in to your College Board account to print your updated admission ticket. You can't get into the test center without it.
Nice to Have
A watch (without an audible alarm)
Extra batteries and backup equipment—you’ll have to ask for permission to access them. They can’t be on your desk during the test.
If you've registered for an upcoming SAT administration, sign into My SAT and click the Print Admission Ticket drop-down menu item. This will open a new window where you can print your admission ticket or save it as a PDF.
