A Braintree secondary school is set to appeal their GCSE results after a slump in the number of pupil passes.

Alec Hunter Academy, based in Stubbs Lane, Braintree, confirmed this week that only 38 per cent of pupils got five or more GCSEs in grade A* to C, including English and maths.

Last year 40 per cent of pupils achieved this.

The headline figure came weeks after the GCSE results were handed to pupils, due to a clerical error by the exam board, which meant that more than 30 pupils were given no marks for an assessment they sat in Year Ten.

A spokeswoman for the AQA exam board apologised for the mistake and said: “When we sent these 31 students their results we hadn’t included their coursework marks, so the results weren’t right."
