It has been researched through certain methods that many of the poor schools that do bad have the least qualified teachers. Other places that are well off have some of the best qualifiesd teachers in terms of credentials. It's not always the case but the worse the teachers are the less motivated the students are too. In order to alter the bad schools some are thinking of bringing better teachers and more money into the schools.
