<p>Do schools mail all the letters at one time? Some posts say they are mailed in waves?</p>
<p>Waves? Several thousand letters would be one or two trays – easily processed by any office. If there were waves, the difference would be a day or two. Unless the office is completely dysfunctional.</p>
<p>thank you, yes, I called the office as some have received a letter, and they stated they were being sent out in “waves”. Hoping I am not being too negative but thinking it meant acceptances were mailed in first wave. :(</p>
<p>Colorado does not have online notification?</p>
<p>no they do not, unfortunately.</p>
