One of Norfolk's premier state schools saw a double-digit fall in pupils gaining the government's GCSE gold standard, while a Norwich academy has revealed it remained well below the government's minimum standard.
Wymondham College this week said 72pc of pupils achieved at least five GCSEs at A*-C, including English and maths, in 2013-14.
The school, which has a mixture of day and boarding pupils, remains among the top-performing in Norfolk, but the figure represents a 14pc point drop on the 86pc it recorded in 2013, as listed by the Department for Education.
The college waited until the outcome of exam grade appeals were known before releasing this summer's results.
City Academy Norwich also delayed making its results public.
In 2012-13, 24pc of pupils gained the government's gold standard. It said the figure had improved to 29pc in 2013-14, but this was still well below the government's 40pc minimum floor standard.
City Academy Norwich principal David Brunton said: 'A key priority for students, parents and teachers is how much progress is made during each student's time in high school. On the new Progress 8 indicator, which measures students' progress across eight GCSEs, taking into account their starting point, the academy's results are in line with the national expectation for this important measure.'
He added that the number of students meeting the government's expected progress in English and maths were up 12pc points and 4pc points, respectively, compared to last year.
Nationally, the proportion of pupils getting the gold standard fell to 56.1pc, from 60.8pc. Across Norfolk, the number fell less steeply, to 52pc, from 54.4pc. Two Norfolk schools have yet to release their GCSE results: Ormiston Victory Academy, in Costessey, and Ormison Venture Academy, in Gorleston.
