Yong Zhao, born and educated in China, is one of our  most perceptive scholars of schools and society. He holds a professorship at the University of Kansas.

In this article, he reports the results of the latest international test, TIMSS. Once again, the East Asian nations topped the charts. Aside from 8th grade math, which are up, U.S. scores are unchanged.

TIMSS (Trends in International Mathematics and Science Study) beat PISA by two weeks. It just released its 2015 results. Within hours of the release, Google News has already collected over 10,000 news stories reacting to the results from around the world, some sad, some happy, some envious, and some confused. The biggest news is, however, nothing new: Children in East Asian countries best at maths. They were the best 20 years ago when TIMSS was first introduced in 1995. They were the best in all subsequent cycles.

Singapore, Hong Kong SAR, Korea, Chinese Taipei, and Japan are the top performers. In 4th grade, the lowest East Asian country is 23 points above the next best country, Northern Ireland for 4th grade, the same gap as was in 2011, and in 8th grade, a whopping 48 points lead ahead of the next best country, Russia, a 17 point increase from 31 in 2011.

Yong Zhao analyzes the reasons for their high scores.
