Stanford's ACT/SAT Rules

So my parents thought it would be best for me to take both the ACT and the SAT this year (I’m currently a junior). I did significantly better on the ACT than on the SAT, and I just saw that Stanford requires that you send both tests if you take both. Should I take the SAT again? Or should I leave the score as it is? Will anything hurt/help me? Thanks!

Don’t worry about this. Just send them both and Stanford will use the higher. They are more likely looking for those students who obsess over scores and take a test many times to get another 10 points.

Thank you so much. That was very helpful. Also, is that from word of mouth or does it say something like that on their admissions site?

@shakashow. @Erin’s Dad is correct. Here is the evidence:
