A lot of immigrants come here and they become parents and they don't necessarily have a lot of education, but they still push their kids to succeed and many do. There are also a lot of black kids who come from disadvantaged backgrounds that do well...so it's a subset, not a whole.
I think parents/guardians have to be involved because the teacher can't be there at night telling the kid not to go out and to stay home and study and to reiterate how important it is to study and do well.
