The Organisation for Economic Co-operation and Development (OECD) published the results of their international student assessments today, revealing that the UK is climbing the world rankings in both reading and science.

The Programme for International Student Assessment (PISA) is undertaken once every three years and tests 15-year-olds' abilities in the core academic disciplines of reading, maths and science.

Launched in 2000, around 540,000 students from 72 countries took part in PISA in 2015, with today's results revealing the top performing countries around the world.

According to the data, the UK has climbed seven places in science, despite scoring a lower average score overall.

This year's report, which has a science focus, revealed that the country has climbed from 21st place in 2012 to 15th place in 2015, despite a fall in point score from 514 to 509.
