„A country’s performance in PISA is […] unrelated to the use of standardised testing. Among countries and economies that perform near the top in science, the use of mandatory standardised tests is widespread in Beijing-Shanghai-Jiangsu-Guangdong (China), Singapore and the United Kingdom, but relatively uncommon in Germany, Korea and Switzerland.“
