<p>That link is for Stanford's School of Education. I think that's different from their undergrad program. I'm assuming you want undergrad info?</p>
<p>Stanford actually doesn't do ED anymore. It's Single Choice Early Action (SCEA). Here's their link for undergrad application deadlines:
<a href="http://www.stanford.edu/dept/uga/applying/1_2f_datesdeadlines.html%5B/url%5D">http://www.stanford.edu/dept/uga/applying/1_2f_datesdeadlines.html</a></p>
<p>SCEA deadline is Nov1, preffered is Dec1, and reg is Dec15</p>
<p>I'm assuming they'll want completed applications so the last date for test-taking would probably be the month before the various deadlines.</p>
