Is UK education the 6th best in the world?

If Finland and South Korea take the first and second places  then...hmmmm.
The ranking table is drawn up by Pearsons and is, of course, based on test results.  Yet again a prescribed, test-based algorithm.   I understand that Finland is very reliant on textbooks and a didactic method.

It brings us back yet again to 'what is education for?' Are we teaching our young people to think , and to be responsible, happy citizens? Or are we teaching them to pass examinations and test which have little validity?

Canada's education system is said to be pretty good - off I go to investigate......
