INTRAC is undertaking a review of Save the Children UK’s Strategic Breakthrough Investment Fund. This is an internal innovation fund that provides funding to ‘test and invest’ in new approaches and tools. A key criteria for projects selected was that they are innovative or unproven and cannot be supported through conventional funding sources. The fund has supported 22 projects in 14 countries between 2016 and 2018. The review is focused at the portfolio level and includes document review and interviews with Save the Children International country offices and technical advisors.
