The open house is very casual. From what I was told last year, the first group had at least a hundred students and the second had around fifty or so. It doesn't matter which one you attend because they won't make any decisions based on your attendence. It starts out with everyone sitting in the lobby talking to current students. You then go into a classroom and the director gives a powerpoint presentation on the program. The professors introduce themselves and talk a little about what they do. After that, you break up into smaller groups to tour some of the classrooms and then meet with a professor to ask questions. The only thing not to like about OSU is that the PT department is in Atwell Hall, a VERY old building.
