More than 580,000 students in 57 countries took part in the study, which tests both ten-year-olds and 14-year-olds in maths and science. The results of the rankings, which are compiled by the International Association for the Evaluation of Educational Achievement, reveal that countries in East Asia continue to dominate the tables in both subjects.
The same five East Asian systems were all in the top six places for science. Russia came fourth in science for 10-year-olds and seventh for 14-year-olds; while Slovenia’s 14-year-olds came fifth.
Singapore topped all four of the rankings' tables. Meanwhile, England's students managed to improve their scores in both the maths and science tables, but in terms of rankings England has slipped slightly in maths, stayed steady in primary science and moved up one place in secondary science.
