A school is only as good as the student. If the student's attitude and aptitude is in the right place, they will excell. My wife's daughter went through Deer Park's schools, and was accepted into The University of Texas at Austin as a freshman. In high school, she studied hard, was a cheerleader, and ended up doing very well at UT.
My neighbors' boys both were able to take advanced courses in high school and one is attending North Carolina State and the other is attending the Merchant Marine Acadamy in New York.
Again, I think it is more about the student than the district.
I hope this helps, and if you have any more questions, please feel free to contact me.
