I attended the Open House at Florida a year ago. It lasted from about 9:30 to 12:30. They served a little breakfast. We all introduced ourselves before the Open House began (maybe because the program coordinator was there and when I attended Open House the PTCAS cycle was open and some students were in the application process). There was an opening speech by the program coordinator, they went over the admissions process, they talked about financial aid options, they introduced a few faculty members, they discussed some clinical internship opportunities we would have there, they talked about their curriculum, the SPTA president spoke, then we had a meet and greet with some current DPT students and we were allowed to ask them questions and they gave us a tour of the Health Sciences Center and took us to a few areas in Shands. After that we went back to where they gave the presentation and we were allowed to ask the coordinator any questions.
Im sure every Open House varies but I think this is probably a pretty standard schedule.
Hope this helps and sorry if it was too wordy. 🙂
