The Center is launching an effort to provide free education on social change action.

The Center exists to advance social change in human rights, public health, education and more. Most funds come from training and members.

NOW, The Center is launching an effort to provide free education on social change action to small grassroots nonprofits, volunteers and those without resources who struggle to be effective.

Every dollar you contribute will be matched by an hour of donated staff time to double the groups being reached.

Please assist the Center in its goal to expand free service to those who cannot pay to receive education and networking opportunities to ensure that social change activities are inclusive and well done.

Theory of Change Japan

We are delighted to announce the establishment of Theory of Change Japan (ToCJ), the Japanese affiliate of the Center for Theory of Change. This couldn’t have happened without the drive of founding Directors Yutaka Tanabe and Motoi Kawabata. Eoin Collins, Director of the Center for Theory of Change in New York is also a director of the new affiliate.

The Center for Theory of Change is a non-profit organization established to promote quality standards and best practice for the development and implementation of Theory of Change, with a particular focus on its use and application in the areas of international development, sustainability, education, human rights and social change. Theory of Change has the power to radically enhance the capacity of social change organizations and initiatives to achieve their goals and demonstrate their impact. It grounds planning and strategy in the reality and evidence base of what is necessary to achieve change. Theory of Change is also critical to evaluation, providing a framework that allows organizations to know what to evaluate and when. It builds on – and can usefully incorporate data gathered through – other approaches that have been developed to improve planning and evaluation, including ‘logic models/logframes’ and ‘results frames’.
