This schools problem is not a teacher or school system problem. It is a parental involvement problem. You have too many parent pushing their job of raising their children on the school. I say make the parent more accountable to their child's education. Make it against the law if you don't get involve when the school has contacted you about your child and maybe we will see some improvement.
This school is supposed to be a 'transformation school' where students are supposedly being taught by the 'best' teachers and led by the 'best' administration. Teachers and administrators are being paid large bonuses to allow children to roam the halls at all times of the day, there is no discipline.
