School-to-School International (STS) is an international development, non-profit organization based in the San Francisco Bay Area. we specialize in providing technical services in international education in three main areas: (1) research and evaluation, (2) curriculum and training, and (3) policy and planning. Since our founding, we have reached more than 50 countries. While the scope of our work in those countries has expanded and changed over the years, our commitment to improving the lives and learning of children has not. Wherever we work, we embody our enduring values and apply the lessons we have learned from developing the Whole Child Model, providing partners with our expertise in inclusive and sustainable practices.
