A headteacher of a secondary school refused to give full figures for the school’s GCSE results after questioning more than 100 marks from one examination board.
Caroline Wilson, principal at Ormiston Sudbury Academy said a detailed view of results would not be made available until the “big challenge” was sorted.
There are 158 students in the year group with potentially 112 students affected by the challenges.
“There’s something not quite right with one board,” Mrs Wilson said.“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.”
Mrs Wilson said there had been several challenges across the country and said the school was speaking to students who may be affected by the exams in question, including those going to local colleges, and said the relevant bodies had been informed of the situation.
“They know we are looking into these grades,” she said.
The school has set a deadline of September 2, to find out if the marks in question will be changed and Mrs Wilson, said: ”We are challenging some grades and will therefore release final figures when these have been received.
She added: “Overall I am happy with the results.
“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 – 11 per cent of all grades secured are A* to A or equivalent.
“On the back of last week’s excellent A level results we have more students able to take their chosen paths including more students staying on with us in to our Sixth Form.”
However, Mrs Wilson admitted the “anomalies” had impacted on the level of progress, which she said could be significantly improved, and on the levels for students on free school meals.
