Three of the borough's secondary schools have been warned to improve their exam results or be shut down.
Ed Balls, the Schools Secretary, has issued an ultimatum - called the National Challenge - to 638 low-performing schools across the country, insisting they improve their GCSE results within three years.
Among those targeted for improvement are Hounslow Manor School, which achieved 26 per cent with five or more good A-Cs last year, as well as Longford Community College (25 per cent) and Feltham Community College (29 per cent).
Hounslow Council was among the local authorities given a 50-day deadline to draw up action plans for the secondary schools.
But a Council spokesman said all three already had detailed plans in place for raising attainment and were 'rapidly improving'.
He added: "Additional data shows that the pupils in these schools make good progress when compared to the level they are at when they start school.
"They have all seen large improvements in their GCSE results in recent years and had successful Ofsted inspections.
"We are confident these schools will continue to improve and meet these new targets."
To accompany the new drive Mr Balls has also pledged £400m of additional funding for low performing schools, some of which may be available to the three in Hounslow.
