Three Decades of Coalition History: 1991-2024

The history overview that follows is drawn from International Coalition of Girls’ Schools archival materials including annual reports, early correspondence, conference programs, news clippings, Coalition publications, and conversations with Meg Moulton, Whitty Ransome, and other foundational leaders. While it is impossible to include every initiative undertaken by ICGS over the last three decades, this history seeks to provide a summary of the major achievements of the Coalition as well as to capture the spirit of determination and collaboration that have led to ICGS and girls’ schools being considered experts on the education of girls.

Creating the Coalition
Consider the shifts in the educational landscape over the last 30 years, and you will see the impact of the International Coalition of Girls’ Schools (ICGS). The social movements of the 1970s and the Title IX push for equal access placed single-sex institutions at risk. Suddenly, single-sex schools were no longer seen as a natural alternative. Despite the historic role of girls’ schools in providing quality education for girls, single-sex education was seen as anachronistic. Girls’ school educators knew otherwise and recognized the urgent need to change the climate and the conversation. 

From the beginning, the Coalition was grounded in research and inspired by collaboration. In the late 1980s, two educators, Rachel Belash, Head of Miss Porter’s School (Connecticut, USA) and President of the Coalition of Girls’ Boarding Schools and Arlene Gibson, Head of Kent Place School (New Jersey, USA) and President of the Coalition of Girls’ Day Schools, each issued a call to action among their respective boarding and day girls’ school colleagues. These visionary women had no doubt about the value and benefit of an all-girls education, not to mention their own deep and well-founded understanding of how girls learn and succeed. Their goal: to systematically document the benefits of single-sex education for girls and share that information broadly.

These professionals knew their observations and understandings would be strengthened through quantitative research. Accordingly, in 1988 and 1990, two different yet related studies were undertaken by the Coalition of Girls’ Boarding Schools (CGBS) and the Coalition of Girls’ Day Schools (CGDS). By researching and promoting the concept of single-sex schooling, the two organizations became leaders in the national dialogue on girls’ and women’s issues.

Strengthened by their new data, the CGBS and CGDS leadership realized there was great power in collective action. In November 1991, 56 independent and religiously-affiliated schools officially came together to form the National Coalition of Girls’ Schools (NCGS). Its first collective undertaking: a comprehensive campaign to heighten the visibility and document the value of the girls’ school experience. Margaret “Meg” Moulton and Whitney “Whitty” Ransome, who had been serving as the Executive Directors of the Coalition of Girls’ Boarding Schools since 1989, were asked to stay on as the founding Executive Directors of NCGS.

1991-2000: A Decade of Growth, A Future of Leadership
Meg and Whitty quickly understood that an entrepreneurial stance was key to the Coalition’s survival. Their collaborative leadership and relentless advocacy on behalf of girls’ schools helped set NCGS on the path to success. Public relations became a main priority during the Coalition’s first decade. The goal was to both increase public awareness of the benefits of single-sex education for girls and to help individual NCGS member schools with their own public relations efforts. Driven by the finding in the CGBS study that many parents perceived girls’ schools to be weak in math and science, NCGS hosted regional and national conferences and produced numerous publications on girls and STEM subjects. These initiatives helped establish NCGS as an expert on girls’ education in the national media.

This first decade of robust, innovative programming set the stage for a future of healthy growth for both NCGS and its member schools. The organization was also forward-thinking from the outset by expanding membership to the two remaining all-girls public schools in the country and international schools during its first two years.

Within a decade, girls’ schools were enjoying a renaissance. Increasing numbers of parents, students, educators, and policymakers came to recognize the benefits of girl-centered education.

2000-2008: Renewed Focus on Research, Continued Strength
As NCGS approached its 10th anniversary, girls’ schools continued to experience growth and strength. NCGS continued to expand its membership, advocate for single-sex education in the media, and provide girls’ schools around the world with quality professional development and networking opportunities.

This decade also saw a renewed focus on research on girls’ schools, including the publication of the Goodman Research Group Study of girls’ school alumnae and research by Dr. Linda Sax at UCLA on graduates of girls’ schools and the transition to college. Both studies affirmed the benefits of girls’ schools. NCGS continued to convene regional and national professional development opportunities for member schools. Financial literacy, STEM, and global education were three key themes in NCGS programming during these years.

2009-2012: Managing Transitions, Securing Foundations
As NCGS approached its 20th anniversary, Whitty and Meg retired successively in 2008 and 2009, and the Board of Trustees faced the challenge of leading the organization through its first significant transition. Their commitment to the NCGS mission and enterprising mindset had established NCGS as a well-respected advocate for girls’ schools, and the Board sought a leader to carry on their legacy. Armed with a commitment to using this time to secure the foundations of the Coalition and ensure financial sustainability, the Board assessed all areas of the organization with the goal of establishing policies and practices that would attract the new leader they sought.

Over the course of a three-year transition that included the executive leadership of Susanne Beck (2009-2011) followed by the interim leadership of Burch Ford, former NCGS Board Chair and then Head of Miss Porter’s School, as President (3/2011-7/2012) and Nancy Mugele as Interim Executive Director (7/2011-6/2012), the Coalition began to set its course for the future.

2012-2018: Embracing a Larger Vision
After an extensive search, the NCGS Board of Trustees announced the selection of Megan Murphy as the next Executive Director beginning July 1, 2012. Megan was charged with the ongoing implementation of the NCGS 2013 Strategic Way Forward goals: to establish NCGS and its member schools as thought-leaders in educating girls, to build a financially robust model for fulfilling the NCGS mission, and to deepen relationships and collaboration with member schools in order to engage, inspire, and sustain membership.

In these years, NCGS supported 200 national and international PK-12 independent, public, charter, and religiously-affiliated schools in 12 countries. The Coalition continued to provide and expand its robust resources and opportunities in the areas of research, professional development, advocacy, and networking.

The Board of Trustees initiated in September 2015 the process of reviewing the Coalition’s mission, vision, and values. New statements about NCGS’s purpose, principles, and practice, which better reflect the Coalition’s focus of supporting girls’ schools globally, were approved.

Looked to as a national and international thought-leader on best practices in girls’ education, NCGS programming was designed to address the following universal themes: leadership; health, wellness, and inclusion; STEAM; civic/community engagement; classroom innovation; strategic school advancement; testing and assessment; and teaching and curriculum. In partnership with 13 strategic partners from around the world, including the UK, Australia, Canada, South Africa, and The Philippines, NCGS hosted the first-ever Global Forum on Girls’ Education, Creating a World of Possibilities, in February 2016. The Global Forum brought together more than 950 educators, researchers, advocates, authors, practitioners, and related industry leaders from 23 countries to exchange ideas about innovative approaches for academic excellence and the healthy development of girls.

This model of worldwide convenings was so well received that the Coalition hosted the next event of its kind two years later. The Global Forum on Girls’ Education II was held in Washington, DC in June 2018. The program included keynote appearances from visionary women including Billie Jean King, Azar Nafisi, Halla Tómasdóttir, Sylvia Acevedo, and Lieutenant Colonel Lucy Giles.

The Coalition Today: INTERNATIONAL Coalition of Girls’ Schoools
As the Coalition’s membership has grown and become more diverse, its reach, influence and scope have expanded too. All professional development, research, advocacy, and networking programs are developed through a kaleidoscopic lens that considers the many types and characteristics of the girls’ schools within the global network. The Coalition is focused on providing greater global value and ensuring continued regional excellence and relevance across the broad network of girls’ schools.

Since 2015, the Coalition’s Board of Directors has held in-depth discussions and assembled various task forces on a wide variety of opportunities and challenges facing girls’ schools. In 2019-20, the Board began focusing on a comprehensive Strategic Visioning process, culminating in the adoption of the Coalition’s vision statement: “To elevate women’s leadership worldwide by educating and empowering students to be ethical, globally minded changemakers.” 

Additionally, the Board affirmed four broad strategic goals to guide the Coalition’s work, including: leading worldwide in girls’ education, promoting best education practices in girls’ schools, advancing girls’ schools, and expanding membership value to our teachers and the students they serve.

While that work proceeded, the Coalition established its signature Global Action Research Collaborative on Girls’ Education—the world’s first action research program that engages girls’ school educators from around the world in informed, collaborative, and disciplined, action research. The program builds both a network of girls’ school educators from around the world and a library of valuable and relevant research on girls’ education. The inaugural cohort began its work in 2020.

That same year, the worldwide COVID-19 pandemic took hold, profoundly changing the way that the Coalition and its member schools approached their vital work and continued to deliver educational resources. Dozens of Learning Circles were developed by the Coalition to bring girls’ school leaders together to discuss their circumstances and find innovative ways to address students’ and faculty members’ needs. Other virtual opportunities for connection were created as well, including professional development gatherings. All of these events helped to solidify the Coalition’s position as a global convener of girls’ school educators, advocates, and allies.

In 2021, the Coalition’s Board of Directors approved the following motion: “To lead worldwide in girls’ education and better reflect its membership, programs and future, NCGS will reposition itself as a global coalition.”

Over the course of the next year, the Coalition worked to reposition itself as the International Coalition of Girls’ Schools. The first official ICGS event, the Global Forum on Girls’ Education III, was held in Boston in June 2022. In a special ceremony during that gathering, the Coalition officially replaced “National” with “International” in its name in order to be more inclusionary and represent its current membership, programs, and future.

Today, the International Coalition of Girls’ Schools serves more than 550 girls’ schools across all sectors in 24 countries. In 2022, ICGS merged with the U.K.-based Association of State Girls’ Schools.

In January 2024, the merger with the Alliance of Girls’ Schools Australasia was finalized and brought an additional 180 schools into ICGS membership. Today, the International Coalition of Girls’ Schools serves more than 550 girls’ schools across all sectors in 24 countries.

Better together.

APPENDIX A – History of the Alliance of Girls’ Schools Australasia, 1991-2023

In September 1991 at the Association of Heads of Independent Schools of Australia (AHISA) conference in Perth, two principals had morning tea together, talking over the issues they faced as leaders of girls’ schools. Ros Otzen (Korowa Anglican Girls’ School, Victoria) and Sylvia Walton (Tintern Anglican Girls’ School, Victoria) both felt that girls’ schools needed their own voice and a forum in which to discuss matters of mutual concern and interest.

Two months later, the principals of Melbourne girls’ schools were invited to meet at Korowa. By the end of the meeting, the Education of Girls in Girls’ Schools Focus Group (EGGSFG) consisted of twenty-two schools. The inaugural conference, The Education of Girls in Girls’ Schools, was held at Methodist Ladies’ College (Victoria) in July 1992 with almost 190 attendees from all over Australia.

In December 1994, EGGSFG ceased to exist and the Alliance of Independent Girls’ Schools of Australia took its place. However, in what Ros Otzen has termed “another visionary leap”, at the first Annual General Meeting in December 1995, members chose to extend the Alliance to include girls’ schools from every sector and to broaden its reach to Australasia to enable New Zealand schools to join.

Ros Otzen later recalled the moment that the founding members decided that “Alliance” most aptly described what they wanted to establish and what this term conveyed: “warm relationships”, “friendly union” and a “shared commitment and purpose”. This was despite the fact that, as she wryly noted, the most serious competitors of girls’ schools are other girls’ schools and that it would be “greatly to the advantage of some of us if others of us closed their doors”. And yet, she wrote, “the inescapable fact is that, rather than turning on each other, we have come together in the Alliance of Girls’ Schools Australasia”.

Girls’ schools had many shared interests in the early 1990s. Some had been approached by boys’ schools to merge and become co-educational. However, principals of girls’ schools felt that boys’ schools were acting in response to the difficulty of filling senior classes in an economic recession and out of the belief that boys do better in a co-educational environment. “It was always held that boys need girls in their schools, as that made for a better learning experience for the boys,” but, as explained by inaugural Alliance president Judy McCowan: “What we learnt was [that] girls without boys were doing much better”.

It was also a time of massive social change. Feminists like Dale Spender (an inaugural patron or, as she preferred, ’matron’ of the Alliance) were challenging stereotypes of women, while in the public sphere, a new conversation was taking place about gender equality. There was, says Judy McCowan, “an extraordinary debate about how to bring women forward in business and the world”. She believes that the Alliance was a group of girls’ schools “responding to a new world” where “equality of opportunity was a major social issue”.

From the beginning, science, mathematics and technology were key to discussions about how to address inequality in education. After attending a National Coalition of Girls’ Schools conference, Science and Girls, in the United States, Judy McCowan realised how important it was for staff of girls’ schools to embrace technology. “The core thinking,” she said, “was that at a girls’ school, girls come first” and this “included encouragement to study maths and sciences”.

The first volume of In Alliance was published in December 1995, providing members with an important vehicle for creating awareness of the philosophy and practice of girls’ schools. Sylvia Walton, inaugural chairman of the Alliance, presented the results of a survey on student feelings of alienation in single-sex and co-educational schools, while an academic researcher presented her findings on the dieting behaviour of girls in single-sex and co-educational schools, thus firmly establishing the Alliance’s reputation for providing the latest research on all aspects of the education of girls to its members.

By 1996 membership had grown to 53 schools and the first Alliance staff conference was held at Ivanhoe Girls’ Grammar School (Victoria). The Alliance was not, however, just about principals and staff of girls’ schools; it was also considered vital that girls be given the same leadership opportunities as boys. The first Student Leadership Conference was held at Ipswich Girls’ Grammar School (Queensland) in 1999. In another first, Lesley Boston of The Mac.Robertson Girls’ High School was the first principal of a government school to serve on the Alliance Executive.

By 2001, membership had nearly doubled again to 90 schools and the first New Zealand member, Anne Mildenhall from Queen Margaret School, Wellington, joined the Alliance Executive. The following year, 2002, saw several significant events: the launch of the first Alliance website, the inaugural Biannual Educators’ Conference in Melbourne, and the first Why a Girls School? brochure was planned after the Alliance Executive rejected the offer of AHISA to come under their umbrella. As Ros Otzen explains:

That was a remarkable moment of spine. By that stage we had developed a conversation among ourselves about the matters that were distressing us, and the things we wanted to know about each other, and those things we wanted the world to know about us. We were at last ready with the ideas and arguments.

By 2023, the Alliance had more than 190 members, including over 30 New Zealand schools. Members also included schools in Asia and Africa. Until the time of its merger with the International Coalition of Girls’ Schools, the Alliance remained firmly committed to the ideals of its founding members to promote the education of girls in girls’ schools, advocating for the outstanding role that girls’ schools play in producing the next generation of female leaders in business, politics, law, public and community service, the creative arts, music, sports, medicine and health, science, technology, engineering, mathematics and the growing field of entrepreneurship.
