Concerns have been raised after new data showed that pupils needed as little as 13 per cent of marks in a higher-tier maths GCSE paper to achieve a "standard pass" in their resits last term.
The grade boundaries for a "standard pass" – a grade 4 in the new higher tier maths GCSE paper – have all dropped from last summer for the three major exam boards.
In Edexcel’s higher mathematics GCSE paper, a pass would have been achieved with 13 per cent of the overall marks in November – compared to 17 per cent in the summer.
Meanwhile, pupils who took the higher maths GCSE paper for AQA needed 17 per cent of the marks to pass – compared to 19 per cent in the summer.
And the grade boundaries for OCR also dropped slightly - from 15.3 per cent of marks needed for a grade 4 in the summer to 15 per cent in November.
