The Good Schools Guide, according to the official website, "comprises some 50 editors, writers, researchers and contributors; mostly parents but some former headteachers.

The guide itself has a brisk, conversational and often irreverent style of review: the website states that because writers do not accept payment from the schools being reviewed, the guide is "in a position to be outspoken, to write and to advise [readers] impartially, without fear of being biased or having a conflict of loyalties.

"[3] The Times Educational Supplement stated that the guide is "...untroubled by the sensibilities of schools and ... cavalier in the face of squawks from those it has offended".

"[5] Similarly, the Financial Times called the guide "one of the best aids for parents...informative and witty.

The GSGI is aimed at English-speaking parents resident outside the UK who want an international education for their children.
