<p>Usually supplemental recs do not use the Teacher Evaluation form. Since USC says that supplemental LORs can be sent but doesn’t give any instructions (that I can find), I think Y has good comments (at the bottom):</p>
<p>The main thing is to mark it as supplemental so it doesn’t get mixed up with your required recs, and have enough identifying info about you so that they can match it to the rest of your application. I would also have them put it on business letterhead if possible.</p>
<p>Yes, that’s right, just be sure they also include identifying information for you so that the school knows which application it goes with. Also, you might ask them to sign across the flap of the envelope, that way the school knows it wasn’t opened.</p>
