<p>Per the college board web site, Stanford requires either the SAT or ACT and recommends, but does not require SAT subject tests. Stanford also says that if you send SAT scores it wants to see all of them (ie no score choice). Technically, it is possible to send the SAT subject scores alone via the college board web site, although I do not know if Stanford would then want to ask you to release all of your SAT scores. My suggestion is to send just the ACT and not any SAT tests, but instead send any AP 5’s you received junior year. Good luck!</p>
