In order to rigorously and independently assess the impacts of these integrated nutrition and livelihoods programmes, DFID has collaborated with research partners and implementation partners to undertake a mixed methods impact evaluation, entitled "Impact Evaluation of the DFID Programme to Accelerate Improved Nutrition for the Extreme Poor in Bangladesh." The evaluation team includes IDS (the lead organisation), IFPRI, ITAD, CNRS, and BRAC University. The evaluation uses mixed quantitative and qualitative methods within a strong theory-based design to assess the impacts of the integrated programmes on nutritional status.
