G30 Schools, formerly G20 Schools, is an association of secondary schools founded by David Wylde of St. Andrew's College, Grahamstown, South Africa and Anthony Seldon of Wellington College, Berkshire, United Kingdom in 2006.[1]
The G30 Schools have an annual conference which aims to bring together a group of school heads who want to look beyond the parochial issues of their own schools and national associations and to discuss key issues facing education and their roles as "educational leaders".
The association includes about 30 schools from about 15 countries, with membership by invitation and a vote of existing members. G30 schools are chosen on two criteria: the reputation of the school and the reputation of the school's leader.
