The number of requests to remark this summer’s examination results rose 36%, i.e. 45,000 GCSE and A-level grades were changed in Wales, England, and Northern Ireland. Brian Lightman, head teachers’ leader, declared that these numbers demonstrate lack of trust in the UK examination system. A representative of Ofqual claimed that marking should be absolutely accurate and fair. General secretary of the Association of School and College Leaders, Mr Lightman, said that the unsolved issues about GCSE English grades were to be blamed for the recent increase in challenges to exam results. A lot of head teachers declared that grades were unfairly lowered, and their suggestions were confirmed with higher grades after remarking. It was estimated that 1 of 50 exam papers was requested to re-mark. And the number of post remarking altered grades increased by 19%, compared to the figures of 2011.
