In both ordinary times and times of crisis, one of the best ways to tackle many of the issues facing the world today — from poverty to gender-based violence to climate change — is to provide primary school-aged girls with a quality education. Despite this, some 122 million girls worldwide are out of school. Too many girls and women are held back by bias, social norms, and expectations influencing the education they receive and the subjects they study. Around the world, 120 million girls — one in 10 — under the age of 20 have experienced sexual violence. Bullying, including gender-based bullying, is a common form of violence taking place in schools. We know that these trends are made worse by the impact of crisis, conflict and climate change on women and girls.
