I consider the following things when I look at PT schools, and these factors really narrow it down for me big time.
I look at places that are near indian reservations b/c my wife works for IHS, and then I look at places that I feel like I can live for 3 years. That usually takes it down a lot! After that, I look at class size- I prefer smaller classes over larger ones, then I look at what hospitals the programs involve in clinical rotations if that sort of information is available. Also programs that offer some sort of out of country experience (ie. traveling to latin america) is always a plus. If the school gets pass all those guys, then I cut them down based on their teaching methods and emphasis, etc. and bam, I have around 10 or so. Good things.
