London school's towering performance in Pisa tests
A school in north London could be among the best in the world after scoring better in international rankings than even top performers like Singapore.
The international Pisa education rankings, published earlier this month, showed UK 15-year-olds were well behind the leaders when it came to maths, science and reading - but a handful of UK schools bucked the trend.
Michael McKenzie, head teacher at Alexandra Park School, says he is "absolutely thrilled" by the results.
And the pupils say it is all down to their "fantastic" teachers.
Overall, England was ranked 21st, Scotland 31st and Wales 42nd - but 15-year-olds from Alexandra Park, one of 206 schools in England randomly selected to take the tests, put in a storming performance.
The average score for Singapore pupils was 535 points, according to Pisa, with pupils in England averaging 500 points.
