A-Level students at sixth-form colleges in the Diss Express area performed better than their national counterparts on a range of measures in the 2011/12 school year.
But performance data released yesterday by the Government showed that students getting grades AAB or better in the so-called facilitating subjects - maths, the sciences, English, geography, languages and history - was below the English average of 9.5 per cent at three of the four local sixth-form colleges.
While Thomas Mills High School in Framlingham scored two per cent above this average, the figure was just one per cent at Hartismere School in Eye, six per cent at Attleborough High School, and eight per cent at Diss High School.
Thomas Mills High School had 117 students sitting A-Levels last year, with 99 per cent achieving two or more A-Levels at grades A*-E, and 96 per cent attaining three or more.
The school’s 2012 average point score per student - worked out by an A* grade making 300 points, an A grade 270, and so on - was 874.4. The English average was 733.
John Jennings, Thomas Mills’ head of sixth form, said: “We were delighted by results from across the ability range. It comes from the hard work of both students and staff.”
Attleborough High School’s average point score in 2012 was 752.2. This rose from 680.6 in 2011 and 663.7 in 2010.
Fifty-four students took A-Levels there last year, with 95 per cent of those earning two or more A-Levels at grades A*-E, and 78 per cent getting three or more within the same boundary. The 2012 English averages were 63.7 per cent, and 55.5 per cent, respectively.
Of the 83 students who sat A-Levels at Diss High School last year, 84 per cent earned two or more A-Levels at grades A*-E. Seventy-three per cent of students got three or more.
The school’s average point score per student in 2012 was 789.5. The figure was 838.2 in 2010, and 845.4 in 2009.
