Successful schools are those which best educate the students, regardless of background. They are not those with students who come in well-educated but show only slight improvement, nor are they schools which use the disadvantage as an excuse for continued low levels of achievement. Instead, successful schools are those which advance the learning of all their children beyond what is expected.
