Philosophy
Originally named the G20 Schools, the G30 was founded in 2006 by Sir Anthony Seldon, the Head of Wellington College, UK and David Wylde, the Head of St Andrew’s College, South Africa. There are up to 30 G30 schools with the significant majority being able to meet annually.
The G30 brings Heads from leading schools together on an annual basis. All participants are encouraged to share their best practice, thoughts, ideas and challenges within a strictly confidential environment. Heads and their spouses appreciate the unique nature of the role of Head and benefit from the sharing amongst the G30 group. Uniquely, the G30 group includes partners of Heads as full conference participants.
Administration costs are kept low and the G30 group does not have a formal constitution, executive structures or offices.
Outside of the annual G30 conferences, G30 Heads are encouraged to exchange ideas and arrange visits for them and their staff to other G30 schools.
The conference program is organised by the current Head of the G30 school. Guest speakers are invited, not just in the field of education but from a broad range of backgrounds and sectors. G30 Heads and partners gain just as much from the cultural immersion in the country and the informal conversations as they do from the formal conference program.
In 2013 a conference for G30 Deputy Heads was hosted by Wellington College, UK and in 2016 at Buckingham Browne & Nichols, USA and Appleby College, Canada.

2025 CONFERENCE
APRIL 4, 2025
CO-HOSTED BY
GEELONG GRAMMER SCHOOL, KINGS COLLEGE
In April 2025, G30 candidates gathered in Australia and New Zealand for a highly engaging conference hosted by Geelong Grammar School and King’s College, Auckland. The programme combined professional dialogue, cultural immersion, and collegial exchange, exemplifying the values of the G30 network.
At Geelong Grammar School, delegates were welcomed to the Corio campus with a Whole Campus Assembly, Welcome to Country and Smoking Ceremony, and a First Nations Light Show. Presentations on the School’s history, philosophy, and strategy were complemented by student-led campus tours and progressive dinners in Senior School boarding houses. Professional learning included sessions with Clinical Psychologist Andrew Fuller and a visit from the Governor of Victoria, with the Geelong Library and Heritage Centre hosting the final evening in Australia.
The conference continued in New Zealand, where King’s College hosted delegates in Auckland. A visit to Waiheke Island provided a memorable cultural experience, with the Piritahi Marae community sharing Māori beliefs, traditions, language, and perspectives on culture and education. Further exploration included visits to central Auckland and Piha on the West Coast. The programme concluded with performances by King’s College Māori and Cultural Groups and a celebratory dinner in the new Performing Arts Centre, featuring motivational speaker Cam Calkoen and student musicians.
Across the conference, key themes included the changing geopolitical context, the balance between academic achievement and wellbeing, the importance of character education, governance, the impact of artificial intelligence on schools, parent engagement, and the value of confidential, non-competitive collegiality within the G30 model.
Geelong Grammar School and King’s College are warmly thanked for their generosity and leadership in hosting the 2025 G30 conference.
2024 CONFERENCE
APRIL 21 - 28, 2024
CO-HOSTED BY
SHREWSBURY SCHOOL, STOWE SCHOOL, WELLINGTON COLLEGE, WINCHESTER COLLEGE (UK)
Shrewsbury School was honoured to host the opening two days of the 2024 G30 Heads’ Conference in the UK. With Charles Darwin, Sir Michael Palin and Sir Philip Sidney amongst its notable alumni, delegates explored the unique history, traditions and language of Salopian culture. After a welcome dinner, guests moved to the Barnes Theatre to enjoy a pupil revue telling the history of the school through dance, drama, poetry and song. The next day we considered the landscape of independent and state education in the UK, before dipping into some of the distinctive heritage of Shrewsbury, discovering the use of ‘spells’ in teaching and learning, with demonstrations from current pupils who spoke for 4 minutes on a chosen quotation. We discussed Artificial Intelligence in learning with the Head of Digital Learning and tried out a range of Salopian activities (rowing, fives, design technology and choral singing). On the second evening, we enjoyed a safari supper with entertainments and story-telling in three of the School’s 12 boarding houses. The programme included valuable delegate ‘circle time’ and concluded with interactive talks on the School’s award-winning Partnership and Community Engagement Programme and unique relationship with The Shewsy, a Youth and Community Club in Everton. We then headed from one great British boarding school to another, alighting at Stowe in glorious sunshine. - Leo Winkley, Head Master of Shrewsbury School
Stowe was delighted to welcome G30 members. The first Headmaster, JF Roxburgh, said that no one should leave Stowe without being able to appreciate beauty for the rest of their lives and the visit began with a rooftop survey of the entire estate followed by a whistle-stop tour of the ducal palace and landscape gardens. This highlighted the importance of the school's partnerships with the National Trust and Stowe House Preservation Trust who have spent the last twenty years conserving and restoring the estate and widening public access. The following day began with a visit to Stowe's partner school, the UTC at Silverstone, which opened in 2013 and specialises in technology and engineering. While we saw plenty of impressive high-performance engineering, we were a little disappointed not to see any racing cars on the legendary Silverstone circuit. Back at Stowe we were introduced to cutting-edge pedagogy by the Head of Teaching and Learning, Luke Radley, while James Tearle, Faculty Chair of Sciences, made the invisible visible by orchestrating controlled explosions. Learning walks around the academic area were followed by co-curricular activities which included tennis, cricket, golf, athletics, riding, drama, beagling and even a demonstration of quidditch. The day ended with dinner and a concert which showcased the versatility of Stowe's musicians. The next day, G30 delegates were welcomed to Chapel which remains the physical and spiritual heart of the school. After a rousing hymn we headed to Winchester... - Dr Anthony Wallersteiner, Head Stowe School
Delegates then travelled to Winchester College, where they were offered a tour of the ancient College buildings, rare collections, museum and school archives, before joining pupils in their boarding houses. There they joined the pupils at the dining table for the daily ‘family’-style meal, during which pupils and adults engage in lively conversation – a key training ground for the development of Winchester’s culture of conversation and inquiry. Talks followed from ground-breaking researchers on ‘Building Belonging in Schools’ (Luke Tryl, More in Common), offering a different approach to embedding inclusivity into a school community, and a thought-provoking workshop on the opportunities and pitfalls of promoting mental health in young people (Jack Andrew, University of Oxford). Delegates also had the opportunity to experience the glories of the English choral tradition with a full Choral Evensong in Chapel. The service included the rare ceremony of induction of a ‘Quirister’ (boy chorister) at the age of 10 into the choir – a tradition that is written into the College’s constitutions, written by William of Wykeham, authorised by Richard II and dating back to 1382. The evening concluded with a dinner in the beautifully preserved 14th Century College Hall. - Elizabeth Stone, Headmaster of Winchester College
The Conference finished where the G30 began back in 2006 at Wellington College. The focus turned to leadership as author, Associate Fellow of the Oxford Character Project, and Director of the Wellington College Leadership and Coaching Institute, Dr Emmie Bidston, reconnected delegates with their own core leadership values and sense of purpose. After the (in)famous and inaugural G30 pub quiz, the final day began with in-depth sharing across the group of the challenges facing school leaders in the modern world, followed by a historical tour of the College and dinner, where guest of honour, Sir Anthony Seldon, spoke brilliantly about his own leadership journey, most recently at Epsom College, and also the history of the G30. A fitting way to finish a brilliant, inspiring and occasionally tiring week. - James Dahl, Master of Wellington College
G30 HEADS CONFERENCE 2023

Sigtunaskolan Humanistiska Läroverket (SSHL) had the great honour to host the G30 Schools Conference 2023 in Sweden. It was wonderful to finally be able to meet again after a three year hiatus due to the pandemic and the conference theme was focused on leadership in a digital world and in education. For the first part of our week together, we travelled from Stockholm to the county of Dalarna, where we explored its culture, art and industrial history. We visited the Falu copper mine, had a guided tour of the Mackmyra distillery, visited the museum of the famous painter Carl Larsson in Sundborn as well as the factory in Nusnäs to see how the Dala horses are produced. We enjoyed the breathtaking views in this beautiful part of the world with wonderful food and learned how the Swedes enjoy their “fika”.
For our final couple of days we travelled to Sigtuna, visiting our school, to learn more about the challenges about the rapid development of the digital world and how it will impact education and the world we live in.
Peng Wu, is the Programme Director of Research at Stellar Capacity, focusing on the impact of technology growth and digital transformation on society, economy, and politics. Merging his knowledge and perspectives from his background in China, the US, and in Europe, Peng leads Stellar Capacity's research programmes with a focus on digital leadership in the realm of future society, emerging technologies, new work and industry models. Peng gave several very interesting lectures which focused on “Leadership in a digital world” and “The Digital and Future School” giving us insights into key technological advancements and their impact on society, business, academia and individuals and how you as a leader become more successful in leading long-term digital change.
We were also inspired by the lecture “Networked leadership in an increasingly uncertain world” with Robin Tiegland, professor (PhD) of Strategy, Management of Digitalization in the Entrepreneurship and Strategy Division at Chalmers University of Technology in Sweden. Her lecturing and research interests reside at the intersection of strategy, technology (especially AI), innovation, and entrepreneurship. Her lecture explored how and why our ability to use networks to reach our goals more efficiently becomes increasingly relevant in a connected world.
It was a great pleasure and privilege for us to host colleagues from all around the world. We would like to thank every participant for your openness to learn and your great friendship where we continue to build on the experience and the great community of the G30 Schools Conference.

G30 Heads Conference 2019
Appleby College and Upper Canada College were honoured to host the 2019 G30 Schools conference in Toronto, Canada. The conference program continued the Melbourne theme of wellbeing, explored the concepts of global disruption and the fourth industrial revolution, and introduced the theme of pluralism, reflecting the regional culture, the core values of Canada, and the wonderful complexity of a globally-minded education.
Conference presenters included Dr Janice Gross Stein, Founding Director of the University of Toronto's Munk School of Global Affairs and Public Policy, Dominic Barton, Managing Partner Emeritus at McKinsey and Co., and as of late 2019, Canada's Ambassador to China, Professor Keith Banting, Professor Emeritus, Political Studies at Queen's University, Dr Nicole Fournier-Sylvester, Education Manager at Canada's Global Centre for Pluralism, Dr Greg Wells, psychologist and author, Dr Rob Thompson, psychologist and author, and Dr Michael Evans, psychologist and author.
In addition to visits at UCC, Branksome Hall and Appleby, delegates dangled from the CN Tower, a Toronto landmark, enjoyed a Toronto Blue Jays baseball game, toured the Aga Khan Museum, visited local art galleries, enjoyed the hit Broadway musical, Come From Away, toured above and behind Niagara Falls and enjoyed the sumptuous cuisine and wine of the Niagara region.
It was a pleasure to learn, grow, and try new activities together with our G30 Schools colleagues.

G30 Heads Conference 2018
In March 2018 it was a pleasure to welcome our G30 School Colleagues to Carey Grammar in Melbourne, Australia. The Future of Young Australians challenged us with the workshop titled ‘The Workforce of Tomorrow Demands a New Mindset’. Maree Crabb informed us about the dangers of ready access to online pornography by young people. Professor Michael Carr-Gregg gave us a crash course on the use of smartphones, web-based programs and biometric devices to improve the wellbeing of students. Former CEO of World Vision Australia, Tim Costello, ran an excellent workshop on the obligations of leading schools to engage with and serve the wider community. Some G30 Head spouses ran a workshop on ‘Being a Spouse of G30 School Head The Highs and Lows’ which was entertaining, but also raw, empathic and supportive. We enjoyed all that Melbourne and the Mornington Peninsula district offers, - glorious food and wine, sunshine and an early morning beach walk and swim. Throughout the conference we learnt much from each other as we shared our best practices and the rewards and challenges of leading a leading school. It was a pleasure to share our city and Carey with our G30 Schools colleagues.

G20 Heads Conference 2017
The G20 Heads gathered under African skies in March 2017, when Brookhouse School in Nairobi, Kenya hosted the conference. Guest of Honour H.E. Margaret Kenyatta, the First Lady of Kenya welcomed the G20 delegates and encouraged them to explore the challenges and opportunities facing 21st Century Kenya. A profoundly moving visit to Seed Academy in the centre of Kibera gave the group firsthand experience of life in Africa's largest urban slum, and led to the G20 spouses spearheading ongoing support of the Seed Academy primary school. Panel sessions with African leaders in the fields of conservation and education examined topics around servant leadership and environmental stewardship. Our safari experience to Lake Nakuru National Park provided a kind of watershed moment in the evolution of our discussions, as the full collegiality of the G20 found its voice. And then there were the animals - orphaned baby elephants, feeding giraffes, a picnic in the middle of Nairobi National Park and game drives around Lake Nakuru. After the splendour of the Rift Valley, we ended our Kenya adventure with a feast at The Carnivore Restaurant, having savoured the rhythms of Africa. It was a pleasure for Brookhouse staff and students to welcome their G20 friends from around the world.
