@I/O Hopeful 2016 If you haven't heard anything by now from a school you are mostly likely rejected or far down on the waitlist. I know that UMSL already had their visit day a week or two ago where they invited students with offers and those on the waitlist. If you didn't get invited to that I would assume that you are rejected. Wouldn't hurt to e-mail at this point as it's nearly April.
For what it's worth, IUPUI is an excellent program and from what I understand their funding package is generous for a master's program.
From someone who went through this last year, good luck to everyone. It will work out in the end, I assure you.
