Nearly 100 students at Heckmondwike Grammar School have had exam results upgraded - in many cases to an A - after a successful appeal.

When only a handful of the 148-strong year group got an A grade in English literature at GCSE level last summer, the school queried the results with the AQA exam board.

It has now succeeded in its appeal and many of the students have been upgraded.

Some pupils have seen their results jump up two grades from B to A* after the exam board accepted they had been harshly judged.

"When the results came in in the summer they just looked very, very odd," said head teacher Mark Tweedle.

The school had expected 50 or 60 of the group to have been awarded A grades. In fact only seven had As and nearly everybody else had a B grade.

The school initially paid for some papers to be remarked. But after staff examined the scripts, the school was eventually successful through the appeal process in getting the entire batch remarked.

"The school has had to present a very detailed case to support the appeal, and naturally I am delighted AQA's chief examiner has endorsed the judgement and experience of our own English staff," Mr Tweedle said.

The results were improved by 104 grades and an additional 62 A* or A grades were awarded.

"I am pleased that justice has been done for these candidates and their teachers," said Mr Tweedle. But he was concerned the appeals process took five months to sort out.

The school's standing in the secondary school league tables, out on Thursday, will be affected as the school's results are actually higher than they will appear in the statistics.
