<p>The [admission</a> FAQ](<a href=“http://www.princeton.edu/admission/applyingforadmission/faq/letters_of_recommendation/]admission”>http://www.princeton.edu/admission/applyingforadmission/faq/letters_of_recommendation/) implies that Princeton would accept an optional letter of recommendation.</p>
<p>Then it directs you to [Learn more about what to include in your admission application](<a href=“http://www.princeton.edu/admission/applyingforadmission/checklist/”>http://www.princeton.edu/admission/applyingforadmission/checklist/</a>) and makes no reference of a third recommendation as an optional supplement.</p>
<p>I’ve [searched</a> the threads](<a href=“princeton optional recommendation - Google Search”>princeton optional recommendation - Google Search) quite a bit and it seems that back when Princeton offered a separate application they included an “optional reference form”. Now that they are common app only, there’s no hint at all on whether they’ll even accept an optional recommendation, or how to send one.</p>
<p>I was wondering how any alumni/current applicants have handled this. I’ve asked a rec from a research mentor but I have no idea how to submit it.</p>
<p>If anyone is submitting an optional recommendation to any of the other Ivy Leagues, I would appreciate their input as well.</p>
<p>Thanks.</p>
