We examined the value-added from KS2 to GCSE for 2012, 2013 and 2014 to see which state selective grammar schools added the most value to their offspring.

A note of caution - the more highly selective a grammar school, the less scope there will be to add value.

Grammar School Value Added Table

Average value added is 1000. Values are averaged across 2012 - 2014 exam results.

  • State school admissions

    School admissions in England are regulated by the Schools Admissions Code, and schools must play fair, ensuring their admissions policy is not only fair but also transparent. Parents must play fair too: schools and local authorities are wising up on parental attempts to circumvent the code, and hundreds of school places are withdrawn every year, sometimes after the child has started school.

  • Grammar schools reviewed in The Good Schools Guide

    Selective grammar schools are often viewed as a great and free alternative to an independent school education. Most have a highly competitive entry, of course, and in areas with large numbers of grammar schools, the remaining non-selective schools tend to suffer from the ‘creaming off’ of the most able pupils.

  • Where to find a state grammar school

    Identifying and locating grammar schools. Grammar schools are located in 36 English local authorities. Almost half of these are considered 'selective authorities' (eg Kent and Buckinghamshire), where around one in five local children are selected for grammar school entry based on ability. The others are areas such as Barnet or Kingston, with only a few grammar schools.

  • Choosing a British boarding school for a child from abroad

    Most UK schools are now genuinely thrilled to welcome foreign students, and no longer regard a cosmopolitan mix as a matter for shame (that they cannot fill the school with home-grown products). Foreign students are perceived to add breadth, excitement, new horizons, not to mention fantastic exam results in exotic languages.
