Thanks for the data, and revealing that the data you built your article on doesn't account for income.

I agree that there is a great deal of differences in students that attend Bellevue schools.  No two are identical after all. 

The point of my comment, for you and the other commentators, is that to only report on ethnicity and results carries the implication that only ethnicity matters.  A clearer statement that income matters a lot, a little , or not at all would have made this a complete article.  Even a reference to a study (from a wider community, if no study was available from BSD) about that correlation would have been an interesting addition to the article.

I'll hang on to my belief that family income matters a lot in educational outcomes, (without defining "a lot"), until I see sufficient evidence is does not. I think there would likely be a wide variance in "how much", and "why" income matters.
