I was in ISM just the other day... the flight school happens to own a few of the planes that I did my primary flight training in back in the mid/late 90s, so I swung by to say hello to those old "friends".
My first impression is that it's any typical "career" flight school. Cheezy uniforms (complete with student uniforms/epaulets). I was not impressed however when I struck up a conversation with a student that had just cancelled his instrument checkride due to the weather. (It was scattered to broken at 2200-3000' and winds 9 gusting to 13 knots, straight down the runway).
Apparently the student/instructor both thought the winds were a bit much and decided to can the ride. As far as I'm concerned, any flight school that can't prepare their students (particularly those at more advanced levels) to deal with a 13 knot wind should probably review their weather minimums for training, or make changes to the curriculum. 13 kts in the upper midwest this time of year is a calm day.
Beyond that, don't know much about the program except for what I saw in my 10-15 minutes of wandering around the school/FBO/ramp. Most of the planes were on the ground the day I was there.
