Just a snip-it from the report- not dismissing your concern.
In a world-class
system like Finland�s, socioeconomic standing is far less
predictive of student achievement. All things being equal,
a low-income student in the United States is far less likely
to do well in school than a low-income student in Finland.
Given the enormous economic impact of educational
achievement, this is one of the best indicators of equal
opportunity in a society, and one on which the United
States fares poorly.
Maybe the higher achievement is based more on the fact that they invest more for their most
promising students rather than the least advanced as seems to be the case here. Of course the issue of why some students are furthest behind in America may have more to do with lack of wealth than lack of ability.
