I believe some are:
-University of Pitts told me that while they get most of their apps by the end of Feb. and they begin reviewing them then, that they are open until June 1st (I verified that on the OTCAS too).
-Winston Salem (deadline is today I believe)
-Unv. of Toledo (OTD program) ongoing until June 1st
-Belmont Unv. (OTD program) deadline today (their supplemental is easy)
-Keuka College - April 1st
-Lenior Rhyne (April 1st, not on the OTCAS, requires 2 recs from OT's)
-Husson Unv. (Rolling, not on the OTCAS)
