A Sudbury secondary school has seen a disappointing dip in its GCSE performance in maths.
Ormiston Sudbury Academy saw 54 per cent of pupils achieve A* to C grades in both maths and English, compared to 59 per cent in maths in 2013, while the English result remained the same.
Principal Caroline Wilson had previously said that a detailed breakdown of results would not be made available until they had been reviewed, with the academy set to challenge some of the grades.
She said that out of 158 students, the results of 112 students were being looked at with a view to potential challenges.
A spokesman for the school said they were still awaiting results from some pieces of coursework, but did not expect these to affect the overall percentages.
On results day, Mrs Wilson said: “There’s something not quite right with one board. We are looking at the whole range, from A* to E.
“This is about all my children. Where we have got anomalies, we are questioning it. If they are an A* student and have got an A, we are checking it.”
At the time, Mrs Wilson admitted the “anomalies” had impacted on the level of progress, which she said could be significantly improved, especially on the levels for students on free school meals.
In more positive news, the school did post an 11 per cent increase in the number of top grades it obtained.
Mrs Wilson said: “In a year of turbulence and uncertainty regarding grade boundaries and changes to marking, we are delighted to report an increase in our top grades.”
Mrs Wilson refused to comment on why she thought grades had dropped in maths.
