GCSE students in Jersey are performing worse than pupils in England.
The statistics, published by the island's Education Department for the first time, show that the number of 16-year-olds achieving 5 GCSEs A* to C in subjects including English and Maths, is lagging behind the UK.
In Jersey, 49.8% of pupils achieved those grades, compared to 53.4% in England.
However, when comparing achievement within Jersey, the 2013/14 contingent of students did much better than the previous year, with a significant improvement in English results.
But girls outperformed the boys. 78% of girls attained 5 GCSEs A* to C, whereas only 65% of boys got the grades.
