Chinese pupils are the brightest in the country after achieving almost 20% more top GCSE grades than their British schoolfriends.
Research by the Department for Education into last year's GCSE grades show pupils from China outperformed every other ethnicity in the key stage 4 exams.
More than 77% of Chinese students bagged five or more GCSEs at grade A* to C or equivalent including English and mathematics GCSEs last year.
In the same exams 60% of white British students achieved the same measure.
Children of travellers, gypsy or Roma ethnicity fared worst in last summer's exams, with only 13% achieving the benchmark results.
The top five performing ethnicities were:
White and Asian
Any other mixed background
Any other Asian background
The bottom performing ethnicities were:
Children of travellers, Gypsy or Roma
White and Black Carribean
Any other Black background
The government study also revealed girls still hold sway in the classroom with 65.7% achieving five or more GCSEs at grade A* to C or equivalent including English and mathematics GCSEs, while only 55.6% of boys did.
The 10.1-point gap is the largest in five years but both sexes fared better last year than in 2009, when boys and girls achieved a pass rate of 47.1 and 54.4% respectively.
