The whole truth and nothing but the truth

Here's a PISA report that reviews changes in student performance between 2000 and 2009. http://www.oecd.org/pisa/pisaproducts/pisa2009/pisa2009resultslearningtrendschangesinstudentperformancesince2000volumev.htm
Most countries are improving, and the worst and poorest countries are improving the most (as you would expect). But many high performing rich countries - including Canada, Finland, Australia, and New Zealand - are deteriorating. These aren't relative scores that compare us to others, they are the summative scores that reflect how our kids are doing year over year. Canadian students did worse across the board - reading, math, and science - in PISA 2009 than in PISA 2000. Our large drop in science seems particularly worrisome.
Other high-achievers continue to improve in absolute terms, in particular Korea and Hong Kong. So regression to the mean isn't a full explanation.
A number of middle-achievers are making large gains which will move them into the high-achieving leagues if sustained, including Latvia, Israel, Poland and Portugal. Dramatic gains by poor countries such as Chile and Peru are propelling them into the middle ranks of education, which will hopefully drive their economies. On the published trend, Chile will pass the US in the PISA rankings before the end of this decade.
It seems to me that education gains that dramatically outpace socioeconomic gains would cast doubt on the claim that poverty is the problem. And also that we should be looking at what strategies put us on the podium in PISA 2000, because what we've done since isn't working.
