<p>From what I understand, you’ll have to send at least one. However, you have to send all of what you send. If you want to send one SAT, you’ll have to send every SAT that you’ve taken. Similarly, if you want to send one ACT, you’ll still have to send all of your ACTs. Whatever you send, you will be required to send every score from that particular test.</p>
<p>However, I can see how you could read the statement on the website and determine that they will want all scores from both companies (ACT and SAT). Decide for yourself:</p>
<p>[Standardized</a> Testing 2009-2010 | Application to Yale College | Freshmen | Office of Undergraduate Admissions](<a href=“http://www.yale.edu/admit/freshmen/application/testing2.html]Standardized”>http://www.yale.edu/admit/freshmen/application/testing2.html) </p>
<p>After all, they are two separate testing services. Will Yale be able to check, for example, with the ACT company to see if scores are available for an applicant who has not submitted ACT scores?</p>
