Trent College are pleased to confirm that the Department of Education has acknowledged the error in the 
The original Department of Education table stated that 35% of Trent College pupils achieved five or more A* to C grades (including English and maths) in 2012. However, the correct figure is 88%. The number of pupils obtaining five or more A* to C grades in all subjects is 92%.
The error was in the number of students that the Department’s calculations were based on. In 2012, 88 Trent College Year 11 students took GCSE exams.
The Department based their calculations on an incorrect figure of 211 students, which appears to have been obtained by mistakenly adding numbers of students in two year groups.
Trent College can also confirm the school has asked the Department of Education to investigate incorrect data published for its 2009 GCSE results too.
Figures on the Department of Education website for Trent College state 55% of students achieved five or more A* to C grades (including English and maths) in 2009. The actual figure should be 95%.
Dr Peter Kelly, Deputy Head (Academic) at Trent College, said: “We are obviously pleased the Department will be publishing a revised table with our corrected GCSE figure for 2012. However, it is extremely frustrating that this error was able to occur in the first instance and the potential damage the widespread publication of this incorrect figure could do for the excellent academic reputation of Trent College.
“We are relying on the good faith of the national and local media to update their published league tables accordingly once the Department issues the new data.
But it is inevitable the original publication of the incorrect data will have also raised a few eyebrows amongst people who will not see the updated tables. For some the damage has already been done.
“What makes this situation even more disappointing is we didn’t have the opportunity to check the data prior to its release, owing to the late arrival of a Department of Education letter alerting us to the situation.
“We continue working with the Department of Education on trying to minimise the impact of this current situation, while also trying to make sure such an error doesn’t occur again in the future. It may only be a number on a bit of paper to some, but for our staff and students that number represents two years of hard work that they deserve to see accurately acknowledged.”
