Here's what we've done since I've worked at my school.
We went up 87 points last year, for the second consecutive year the highest improving school in the entire county. In three years we have gone from the worst middle school in the District to the best middle school. We are the first middle school in the District to score 700, the first to be qualified as "Basic."
Moreover, we have done while accepting every student into our home, regardless of aptitude or attitude. We have done it in the historical "gang school," the place with the highest concentration of English Language Learners, one of, if not the highest percentage of students qualifying for free and reduced lunch.
We have done it, and turn now toward solidifying and institutionalizing our success, moving now from okay, to good/great, becoming a boring school that does nothing be prepare the kids that would not otherwise get the chance.
