“Shanghainese and Hong Kong students are much better educated than those elsewhere in China. Slate quoted the Brookings Institution’s Tom Loveless as saying that “About 84 percent of Shanghai high school graduates go to college, compared to 24 percent nationally.” In addition, Loveless points out that affluent Shanghainese parents will spend large sums on extra tuition for the children — paying fees that far exceed what an average worker makes in a year.”China has simply cherry picked their most affluent students for testing, and completely omitted the majority of their people. In fact, Chinese rural education policy is geared almost entirely towards attendance and not testing. Poorer students from the countryside that happen to live in Shanghai, but are designated by the government as “non-residents,” are routinely denied access to the city’s high schools as not to tarnish the city’s PISA ranking.
However, comparing Finish test scores to American and British ones is a bit like comparing apples to oranges. Rafael Irizarry at Simply Statistics graphed data provided by the NASSP to show just how well affluent American students compare to their like-minded Finish counterparts.
“The plot on the left shows PISA scores versus the percent of students living in poverty for several countries. There is a pattern suggesting that higher poverty rates are associated with lower PISA scores. In the plot on the right, US schools are stratified by % poverty (orange points). The regression line is the same. Some countries are added (purple) for comparative purposes (the post does not provide their poverty rates). Note that US school with poverty rates comparable to Finland's (below 10%) outperform Finland and schools in the 10-24% range aren't far behind. So why should these schools change what they are doing? Schools with poverty rates above 25% are another story.”This glaring fact is rarely addressed in coverage related to the PISA, and adds much needed perspective to the problems facing our education systems.
