Sobering. Britain ranked 26th and the USA 36th.
Can the UK use the excuse that English is a difficult language to learn? (Ignoring the fact that Australia ranks higher than the UK)
English feels difficult to learn, and part of that is the vast amount of language we get from other countries. Does Japanese have that problem? I know that they have Pan for bread which they got from Portuguese, but do they have as many imports as English?

I guess not since Canada, New Zealand and Ireland are all higher as well.
1. The raw data (answers, in particular the free response text) has never to my knowledge been published. 2. The algorithm used to select schools and pupils taking the test has never to my knowledge been published. (In fact it differs from country to country...or city..) 3. The test itself is taken in many different languages, which language version of the test is used in which country, has to my knowledge never been published. 4. They compare Shanghai, a relatively well off city with entire countries..without knowing the data in 1-3 we cannot know if this comparison is fair or makes any sense at all. 5. They administer the test at different times of the year relative to exam time...some teenagers would have just got back from summer break, others would have been deep revision, preparing for other exams - I would guess this has a statistically significant impact on performance.
Until they publish all the data so it can be analysed independently (and god forbid replicated), this isn't science or statistics...it's busy work.
