If a family decides that a program is a better fit for there child then
1. Its a compliment to that school that there doing something right.
2. Not so much from the school they came from.

Many things can be contributors to this. Politics being the biggest. Kids only get a short time to do whatever it is they are going to do. I say if there parents are able to make it happen for them then more power to them. A transfer is just a symptom.
Take care of the home front and give kids a reason to be proud of there school but in the meantime, mind your business and stop with the victim mentality. The easiest thing to do is always point the finger somewhere else and assign blame to some other person, any other person. Perhaps you are the problem.
