A group of 71 British maths teachers arrived in Shanghai yesterday to learn from local teachers and swap tips on methods and experience.

This is the third batch of British teachers to come to Shanghai under an exchange program launched by China and the UK after Shanghai students topped the 2012 international PISA tests for maths, in which the UK ranked 26th.

PISA — or the Program for International Student Assessment — is a worldwide assessment by the OECD of 15-year-old students to assess skills in mathematics, science and reading.
