There has long been concern that the PISA international tests are “fixed.” Years ago, Tom Loveless of the Brookings Institution criticized PISA for ignoring the selection of Chinese students that are tested. Loveless pointed out that students in Shanghai are in no way representative of students in China.

In this article, Gary Sands reviews the problems of sampling from each country and how some countries can “rig” the samples, which invalidate the results.

Read the article for the details.

Sand concludes:

At face value, the PISA results appear to be a huge propaganda victory for the educational systems of Asians and the Chinese. But the real danger in widely circulating the PISA results lies not in fooling thousands of headline readers around the world, but in the complicit cover-up of the huge disparities in education among Asian provinces. Almost two-thirds of all Chinese children live in rural areas, where school attendance rates can be as low as 40%. A survey by the China Association for Science and Technology showed only 6.2% of the Chinese people held basic science literacy in 2015.

By allowing countries to potentially rig the test, the OECD is failing in its mandate to help governments foster prosperity by providing information. In the case of the bizarre B-S-J-G grouping, PISA administrators have again made another exception for China—just as many foreign businesses have been forced to do—in the hope that the nation will eventually play by the rules. Perhaps the OECD’s intention in allowing cities and groups of cities/regions to compete is to coax China and others into eventually releasing nationwide results.

But in so doing, the OECD is merely kowtowing to Beijing, acquiescing in the samples submitted by other countries and sending a message to our children that bending the rules is acceptable.
