This case study highlights groundbreaking country-led action to end violence against children and youth from a decade of the partnership’s collective work in Tanzania. The study showcases how the government of Tanzania and multi-sectoral partners used the results of the Violence Against Children and Youth Report (VACS) to catalyze action. The national response to the survey is a powerful display of government commitment to use the data from the VACS to inform policies and actions in addressing violence against children for years to come, which is now the standard Together for Girls model.
