The International Coalition of Girls' Schools is a leading global advocate for female-only education, representing over 550 schools across 21 countries. Formerly known as the National Coalition of Girls' Schools (NCGS), it expanded its remit through significant mergers, including joining with the UK’s Association of State Girls’ Schools and the Girls' Day School Trust (GDST). The coalition focuses on advancing women's leadership through research, professional development, and networking. It serves as a collaborative platform for heads and teachers to share best practices in pedagogy and pastoral care, specifically tailored to the empowerment of girls.
