The average percentage for 16-year-olds with grades A-C at GCSE, including Maths and English, across England is 46.7% – for Lincolnshire's 8400 pupils taking GCSE at 16 it is 50.6% – the second highest for education authorities in the East Midlands (Rutland is 58%). Some schools in Lincolnshire are woefully below this level. For the St Clement's College in Skegness, it is 5% – the lowest in Lincolnshire (although it is a secondary modern) and the third lowest result in England, but for the low-performing comprehensive Joseph Ruston College in Lincoln, it is 13% – the government target is 25% for comprehensives. For the St Bede's Catholic Science College in Boston and the Castle Hills Community College in Gainsborough it is 8% – these are secondary moderns. Lincoln has no selective schools, although its Priory School is a surrogate. It is also the largest school in Lincolnshire. The best performing secondary modern is St. George's College of Technology in Sleaford, which achieves results better than twelve comprehensives.
