Celebrating its tenth anniversary, the Global Women’s Institute (GWI) is a world leader in research and action to end gender-based violence. Over the last decade, GWI has proven that violence is preventable, documenting a 70% reduction in partner violence in Nicaragua and a 45% reduction in Haiti through community-led models. By leading the global "What Works" consortium and launching the GenderPro professional certification, GWI bridges the gap between grassroots activism and international policy, providing the evidence and training needed to protect women in both stable and conflict-affected settings.
