It's not the OT program that sent it, it's the graduate college in general. You know how we had to apply to TSU's grad school through their website and pay the additional $30? That's what this is for. I declined an interview when they offered (I've already been accepted locally) and I also received the email today. I'm sure it's because we submitted all of our transcripts, GRE, etc to OTCAS and the graduate college itself doesn't have all of your info. I would just give them a call to clarify what info needs to be sent with them and if there is still confusion I would contact the head of admissions in the OT department! Hope this helps!
