OP wasn’t asking about Rice, I just used that as example because we just happened to get that email today. They want them all, this is from the email:

“As you may know, Rice University requires all applicants to submit either SAT scores and the results of two SAT Subject Tests or to submit results from the ACT. We have no preference between these two options, nor do we have a preference for the old SAT or the new, redesigned SAT. If you take either exam more than once, we will use only your highest individual section scores, in the case of the SAT, or your highest composite ACT score, in our evaluation.
In order to ensure every applicant benefits from this policy, we require the results of all such exams be submitted to Rice. If you have taken the SAT, SAT Subject Tests, or the ACT and elected to suppress the release of any of your scores, please release them now to ensure that you meet our application deadlines.”

Just fyi for this particular school.
