With results received from 25 of 26 schools, provisional results show 57 per cent of students across the county received five or more A* to C grades including English and mathematics – slightly down on last year’s figure of 59%.
Eleven schools are reporting results that are in line with or better than last year’s.
Councillor Nick Bennett (pictured), East Sussex County Council lead member for learning and school effectiveness, said: “Given the volatility in GCSE results being reported nationally this year following significant changes to the exam system, we are pleased to see that young people in East Sussex schools have achieved well.
“I would like to congratulate pupils for the effort they’ve put in to achieve these results.
“Attaining good GCSE grades gives young people a solid grounding for their future educational and professional life, and their success is the fruit of many months of hard work by students and staff alike.”
