And at A level, AQA increased its market share from 45.4 per cent in 2018-19 to 45.7 per cent. OCR saw a slight decrease in its market share from 21.6 per cent to 21 per cent, with the other boards’ shares remaining broadly stable.

Pearson’s market share remained the same at 26.7 per cent, while WJEC’s increased from 6.3 per cent to 6.5 per cent.

“In the A-level qualifications market, only OCR has slightly decreased its share (down by just below 1 per cent),” Ofqual’s report says.

“The largest decrease was in its market share in other modern languages subjects (down by 16 per cent). This is due to OCR no longer offering qualifications in these subjects,” it adds.

The top 10 highest volume subjects account for 80 per cent of all GCSE certificates, 1 percentage point more than in 2018-19.

AQA has the largest market share in eight of the 10 highest volume subjects. Pearson has the largest share in the remaining two subjects; mathematics and history.
