The Organization for Economic Cooperation and Development (OECD), which oversees the Program in International Student Assessment (PISA), has released a lengthy study comparing the nations that take the PISA test.

The conclusions of the report confirm what almost everyone knows: the students with the lowest test scores are those who live in poverty, those who have an immigrant background, and those who live in a single-parent home (which is usually a female parent, who usually lacks the income to support the family). These findings are not surprising.

How does the US compare? Apparently there have been no changes in reading scores since 2003—despite No Child Left Behind and Race to the Top and their heavy emphasis on reading and math. There were some gains in science, which is surprising since science was not a priority subject for either of the  big federal programs.

So how does the U.S. stack up…
