<p>^From the freshman admissions section of Penn’s website:</p>
<p>Required Tests</p>
<p>The American College Test with Writing, may be used in lieu of the SAT Reasoning Test and two SAT Subject Tests. Penn requires that applicants submit all testing results from each administration of the ACT, SAT, and SAT Subject Tests. We evaluate only the highest of your ACT Composite scores, the highest score on each section of the SAT, or the highest single testing result from multiple sittings of any SAT Subject Test. </p>
<p>The SAT
•Freshman applicants must take the SAT Reasoning Test and two SAT Subject Tests.
•Candidates to the School of Engineering and Applied Science or the Wharton School are encouraged to take a Mathematics Subject Test.
•Students interested in science-related fields, and especially applicants to the School of Engineering and Applied Science and the School of Nursing, are encouraged to take a science Subject Test.
•Registration materials for the SAT Reasoning Test and SAT Subject Tests may be obtained from your guidance office.</p>
<p>The ACT
The American College Test with Writing, may be used in lieu of the SAT Reasoning Test and two SAT Subject Tests. </p>
<p>When to Take the Tests</p>
<p>•Early Decision candidates should take these examinations either during the junior year or in the summer before the senior year, but no later than November 2009. Early Decision candidates who opt for November examinations must rush their test scores to us.
•Regular Decision candidates should complete all testing by December of their senior year. First-time testing delayed until January will place the applicant at a disadvantage in our evaluation process. Tests retaken in January will be accepted.
•Please Note: Using the score suppression option may result in scores not being received by the applicable deadline.</p>
<p>Perhaps I missed it, but where does it say that Penn prefers the SAT over the ACT? Doesn’t it actually say that an applicant may substitute the ACT with writing for the SAT I and two SAT subjects tests?</p>
