<p>Princeton said that they didn't receive one of my teacher recs. However, she already sent it December, 2009 through paper mail. I suppose she should send it again, but should she include an explanation letter along with it?</p>
<p>Also, trying to find the mailing address to each college is annoying, they rarely make it clear where they want recommendations to be mailed to. </p>
<p>I suppose the princeton address is:</p>

<p>Correct me if I'm wrong.</p>
<p>I wonder how often this happens… D1 had 3 schools telling me that they hadn’t received her transcripts and rec (also sent USPS) and then, magically, they arrived that day or the next. It seemed to take about 2 weeks to arrive at the right place within the campus. D1 was phoned with an acceptance to one of those schools the next day!</p>
<p>D2 was just notified of something “missing” that was sent in December too. We faxed it over this afternoon and will call Monday to make sure they got it.</p>
<p>I think the schools get more mail than Santa Claus this time of year and processing takes forever. I would ask the teacher to resend the letter and even call (if they can) to reassure Princeton that it was sent earlier and that both letters are the same.</p>
<p>I got the email about a missing rec letter too and it clearly says in the email where to send the forms, as well as a fax number. If going through postal, send the letter to </p>

<p>I don’t think an explanation is needed. Things get lost in the shuffle. I’m sure it happens all the time.</p>
<p>I remember this happened to my daughter several years ago with a different college. Her teacher faxed the rec to the school with a hand written cover-note, “If you don’t take this (some complimentary adjective) student, you’ll be making a huge mistake.” She got in. 
Her teacher told me this story at the end of the year, pleased that my daughter chose that college. </p>
<p>I think it’s a good sign that they’re asking for it at this time. It very likely means that they are seriously considering your application.</p>
