Mixed results in league tables
The new requirements for GCSE students in last year's exams have produced a different borough picture in this year's secondary school league tables.
Bexley Grammar School in Danson Lane, Welling, was the only school in the borough where every pupil taking the exams achieved the Government's target of at least five A* to C grades including
maths and English.
Its results were among the top 60 in the country.
Townley Grammar School in Bexleyheath achieved 99 per cent while at Beths and Chislehurst and Sidcup grammar schools, 97 per cent of exam candidates achieved the new "gold standard."
Consistently high achieving St Catherine's Catholic Girls' School in Bexleyheath, was the highest placed non-selective school with 70 per cent of its pupils getting the desired grades.
At the Bexley Business Academy in Thamesmead, 27 per cent of pupils received at least five top grades including English and maths - above Erith School with 21 per cent and Westwood College,
Welling, with 17 per cent, and just behind Cleeve Park School, Sidcup which achieved 30 per cent.
Hurstmere Foundation School for Boys in Hurst Road, Sidcup, was in the top 50 most improved schools over the past three years.
This year 42 per cent of boys got the top grades in the required exams.
Andy Stringer, head teacher at Hurstmere, told News Shopper: "I am immensely proud of the staff and the boys and grateful for the support of parents."
He added: "Becoming a specialist sports college four years ago made a big difference. It has brought additional money and resources to the school and sport is a big motivator, especially for boys.
But there are many different aspects to bringing about changes and it is difficult to identify just one."
The task is all the more diffiicult at a boys only schools as on average, boys achieve 10 per lower marks than girls.
Mr Stringer says the specialist college status and subsequent exam improvements have had a knock-on effect on the school.
He explained: "When I came to the school seven years ago there were 120 applications for 180 places; last year there were 800 for 200 places.
"The school is now vastly over-subscribed and very popular."

The national average for pupils gaining all the required results was 45.8 per cent and in Bexley it was 50.3 per cent, although only six of Bexley's 14 secondary schools achieved the national
