It's the same here ---there are schools that are 95% or more hispanic and they've done everything they could to make them their schools, most classes are bilingual and only Mexican culture is taught, almost all school meals are tacos and enchildadas ---and the whites still do better. What more can be done?
Could it be possible that more (though certainly not all) of white and Asian parents place a higher emphasis on education and actually expect their children to pass their classes?
