Empowered Worldview (EWV) is a faith-based programming model and training curriculum that seeks to transform mindsets toward hope, compassionate relationships, self-reliance and faith-in-action. Empowered Worldview was developed in 2015 by World Vision in Tanzania and by 2023 had been implemented by World Vision in 40 countries. An assessment of the implementation of EWV in two high-need contexts in rural Tanzania was undertaken by World Vision Tanzania, Ifakara Health Institute and the University of Alberta, with data collected between 2020 and 2022, and analysis carried out in 2022 and 2023. Quantitative and qualitative methods were combined to assess baseline conditions, implementation process and impacts of the first two years of implementation. Special attention was paid to assessment of mindset, as a key intermediate outcome, and child nutrition as an ultimate outcome.
