DECDI: Development Impact (DECDI) is a department of the World Bank’s Development Economics Vice Presidency (DEC). DECDI’s objective is to increase the use of impact evaluation (IE) in the design and implementation of public policy, to (i) improve World Bank and other MDB funded development projects and public policy to deliver better outcomes, (ii) strengthen country institutions for evidence - based policy making and (iii) generate knowledge in strategic development areas. With engagements in over 60 countries across 200 agencies, leveraging a US$180 million research budget to shape the design and implementation of US$18 billion in development finance, DECDI aims to overcome the challenge to identify true cause-and-effect relations in policy programs. By linking researchers to policymakers and feeding results back into policies, DECDI foster systematic use of evidence, which informs adoption, mid-course corrections, and scale-up of policies.

The impact evaluation: This impact evaluation will assess the impact of provision of home-grown school meals on children’s educational and nutritional outcomes in Zambia.  This evaluation will be conducted in partnership between the Ministry of Education, World Food Programme (WFP) Office of Evaluation (OEV), the WFP Zambia country office (CO), the World Bank’s Development Impact (DECDI) department.

The data collection: DECDI is seeking a survey firm to conduct baseline data collection activities for the evaluation in three (3) regions of Zambia in September 2025. The data collection will have to be conducted using tablets.

Data collection will involve the following data collection processes:

•                     Principal/Head teacher survey: Two-hour interviews with headteachers from the sample of approximately 200  (final number to be confirmed) schools;

•                     Child survey + anthropometric measures: one-hour interviews and anthropometrics measurement with the sample of approximately 2000 (final number to be confirmed) school children
