Five schools in Hounslow have won praise after finishing in the top 100 nationally for their results.
The Heathland School, Lampton Academy, Heston Community School, Brentford School for Girls and St Mark's Catholic School all received letters from schools minister Nick Gibb recognising their achievements.
The Heathland School featured in the top 100 non-selective state schools for the percentage of pupils achieving five or more A*-C GCSEs including English and maths.
The school in Wellington Road South, Hounslow, was also in the top 100 non-selective state schools for its KS2-KS4 value added score - a measure of the improvement made by pupils since joining - alongside Lampton Academy, in Lampton Road, Hounslow.
In his letters to the three schools, Mr Gibb wrote: "Thank you for your work in this important area of a young person's education and congratulations again to you and your staff for you (sic) hard work and professionalism."
At The Heathland School, 80% of students achieved five or more A*-C grades including English and maths in their GCSEs last summer - a huge leap from 66% the previous year.
Its best 8 value added score was 1,039 - well ahead of the benchmark figure of 1,000, which represents expected progress.
Headteacher Harinder Pattar said: "We were delighted to receive a letter of congratulations from the minister. To be amongst the best 100 non-selective schools in England is a tremendous accolade. It is further recognition of the motivation to succeed that Heathland staff foster amongst our pupils."
At Lampton Academy, the proportion of students getting five or more top GCSEs including English and maths fell slightly last year, from 64% to 62%, but its best 8 value added score was an impressive 1,036.
Headteacher Stephen Davis said: "We are very pleased and proud to be placed in the top 100 schools nationally. This achievement acknowledges the hard work of every member of our school community in ensuring that all pupils make outstanding progress throughout their time at Lampton."
Headteacher at Brentford School for Girls on Boston Manor Road, Marais Leenders added: “I am incredibly pleased that once again the school has been commended for its fantastic examination results.
“The students and staff work so hard at Brentford to ensure that every student achieves their full potential, achieving not just academically but also developing the wider skills which are so critical for future adult success.”
Headteacher at Heston Community School, Phil Ward, who was delighted to receive the letter, said: “We are very pleased to be one of the “Top 100” schools nationally for our value-added achievement which is thanks to the hard work and enthusiasm from both our teachers and our students.”
St Mark's Catholic School, in Bath Road, Hounslow, made the top 100 in no fewer than three categories: five or more GCSEs at A*-C including English and maths, percentage of students achieving the English Baccalaureate and pupils' value-added progress.
Headteacher Paul Enright said the school was delighted to be included in the top 100 again, and described the achievement as a testament to the hard work of staff and students, and to to the strong support from parents.
