<p>I'm also graduating in 2006 and interested in Stanford. On the admissions website, it says "In the first year that the new SAT I is phased in, beginning with the March 2005 test date, we want to provide our applicants with flexibility. For students applying to Stanford for Fall 2006, we will accept a student's highest individual verbal score and math score from either the old SAT I, the new SAT I, or a combination of the two exams." </p>
<p>So no, you don't have to take the new SAT. However, 3 SAT II's are required, one of which has to be Math 2C. If you're going to use an old SAT score, I'd recommend that you take the SAT II Writing before March (which is what I'm planning on doing). That way, you'll have a standardized writing score to send.</p>
