GCSE and A-level exam results for Haringey schools were released by the Government on Wednesday.

The tables, published by the Department of Children, Schools and Families, have been revised since last year to take into account remarkings and adjustments.

All of the borough's schools beat the Government's target of 30 per cent of pupils achieving five or more GCSEs at grade A* - C, including core subjects maths and English.

As well as measuring the percentage of GCSE and A-level passes, the new figures also give a "value added" score to show the progress made by children between key stages.

Fortismere and Alexandra Park School, both in Muswell Hill, claimed the title of Haringey's top-performing schools in terms of A* - C passes, with 73 per cent and 62 per cent of pupils, respectively, achieving the top grades.

But Alexandra Park was the clear winner when it came to adding value to its pupils, to the delight of the school's headteacher.

"It's exceptional for a school to get excellent results and add value to so many students", said Michael McKenzie.

"High performing schools rarely add the kind of value that we achieved last year.

"When taken together our great results and the increase in performance by our students from 11 to 16 represent an outstanding achievement that every member of staff and every student can be proud of.

"Our percentage of A*-C grades has improved year on year and our value added is far above average. Few other schools in the country can claim to be in this position."

The good news continued at Woodside High, in Wood Green, which was named one of the most improved schools in London for it's 10 percentage point increase in top grades.

Joan McVittie, head at Woodside High, put the improvement down to a total change of culture at the school.

"When I arrived the school had a reputation as the worst in London," she said.

"But since then we've changed the school's name, designed a new uniform and created an ethos where it's OK to be seen to work hard. This is all down to the superb students and a very strong leadership team.

Mrs McVittie was also keen to encourage parents to consider Woodside High when choosing where to send their children.

She added: "Parents should take a long hard look at the school. There's a belief that there are better schools locally, but there really aren't."

At the other end of the scale, Park View Academy in Tottenham was the borough's worst-performing school - just narrowly scraping 31 per cent of the all-important five or more A* - C GCSEs.

But headteacher Alex Atherton preferred to focus on the value added element.

He said: "I'm delighted the results confirm Park View's reputation for value added. When you look at the tables in that way, we're ahead of Fortismere.

"Two thirds of our pupils do not speak English as their first language so I'm proud of what we've achieved because it represents what we do with the children we have. It shows that we make progress."
