Sampling error.

Our education system takes in and tests a wider variety of people, and the favored countries put most of their population on rigid tracks (or streams) that are unlikely to receive international tests.

It’s an easy way for others to shove the US down the ranks while feigning a sense of “scientific validity”.

The North Shore of Long Island has some of the best schools in the United States.

The students take the International Tests at the 4th, 8th and 12th grade and guess what?

They score on average, higher than the top 5 countries on the list.

Here’s the other thing — the Koreans and Taiwanese immigrants in New York score HIGHER on average than the Koreans and Taiwanese in Korea and Taiwan.

Go figure.
