The children of Vietnamese refugees in San Diego had an after school regimen of homework at the kitchen table. The kids enjoyed a stunning academic success. My sons were raised in that community. My middle son was inspired and finished with a 4.33 GPA and scores of 5 on all AP exams. What happens at home after school matters. I pushed a much higher standard of English, math and science than the school provided.
This school was actually a well-performing school following the Vietnam War when Osborn was a popular resettlement area for Hmong refugees... not surprising. Since those families departed years ago, the school transitioned to one in which ~1% of incoming freshmen passed the state standards test as seniors (with ~80% dropping out of school). It is not the state or the school that has failed them... it is the community/social fabric that believes the government can be a substitute for a functioning family.
