2nd time said "need" not deserve. The reason poor students need better teachers is that wealthier families usually can pick up the slack of less effective teachers. Therefore students whose parents can't pick up the slack of a less effective teacher really do need that teacher more whether it is fair or not. They have the higher need. That doesn't mean that one deserves the better teacher or should get a crappy teacher. I agree that parents are usually the difference in high performing students. I also believe that minimally effective teachers hide in wealthier schools and districts because the parents supplement their child's learning. I also believe minimally effective teachers can hide in poor schools and districts because the students and the parents can be blamed for the poor performance.
