By researching and promoting the concept of single-gender schooling, the Coalition of Girls' Boarding Schools and the Coalition of Girls' Day Schools became leaders in the national dialogue on girls' and women's issues. Those educators who were experienced with teaching only girls were determined to use the two studies to paint a different picture of the role of girls' schools in American education. The findings of the studies gave administrators in girls' schools important talking points for future marketing and promotional literature.Strengthened by their new data, the CGBS and CGDS leadership realized there was great power in collective action. In November 1991, the steering committees of both organizations met and agreed to merge. Fifty-six independent and religiously-affiliated schools officially came together to form the National Coalition of Girls' Schools. Its first collective undertaking: a comprehensive campaign to heighten the visibility and document the value of the girls' school experience.
