ESSEX has yet again proved to have a large number of top performing schools.
The four selective schools in Chelmsford and Colchester all make the top 25 of the best state secondary schools in the country according to the 2008 Sunday Times Parent Power survey.
Widely acknowledged to be the most authoritative, placings in the tables are calculated on pupils' performance in public examinations.
Chelmsford's two selective schools are both highly placed in the top 500 state secondary schools league table. King Edward VI Grammar is at 12, similar to its 10th place last year, while Chelmsford County High school for Girls is at 25.
Colchester Royal Grammar School is at 10 and Colchester County High School for Girls at number 11.
KEGS headmaster Tom Sherrington said: "We are absolutely delighted to be in the top 15 of this prestigious list and number one in Chelmsford. Our students and staff work extremely hard and it is wonderful to be recognised in this way."
St John Payne Catholic Comprehensive, Chelmsford, is ranked at 205, up from 237, and William de Ferrers is at 479, compared to 403 in 2007. Boswells School in Springfield is a new entry to the table at 487th.
The ranking is based on the percentage of A-level entries returning A and B grades and the percentage of GCSE entries returning A* and A grades in summer 2008.
Just months after being seen as outstanding by Ofsted, Woodville Primary School in South Woodham Ferrers is ranked the highest scoring Essex school in the survey's top 500 state primary school league table. It is placed at number 61, bettering its 2007 ranking of 76th place.
Two other Chelmsford primary schools feature in the list: Danbury Park Community Primary School is at 489, down from 336 last year and the Tyrrells School in Springfield is at number 328, a rise from 365 in 2007.
The ranking is based on the aggregate of Key Stage 2, Level 4 results in English, maths and science in 2005, 2006 and 2007.
Only schools where 20 or more children were entered for Sats on average over the three years are included.
