The majority of students at Whittier come from families with low incomes and are second language learners. These are the two greatest factors that influence scores NOT teachers as our illustriious governor and her unqualified sec. of ed. would have the public believe. Because the neighborhood has abandoned the school the percentage of middle and upper middle income students is absent further compounding the low test scores. There are some high scoring schools I wouldn't put my child in and I transfered into a "low-performing" school so she could learn a second language. The "low performing" school had excellent teachers and resources.
If you really want to know a school visit it!
And yes, you and your neighbors should support your neighborhood school it is a reflection of you.
