Process Evaluation

What is process evaluation and why is it important?

The Environmental Health Group has increasingly been involved in conducting process evaluations of WASH interventions to document programme activities and the extent to which they are delivered and implemented as planned. Process evaluations are extremely useful to feed back in the programme life cycle and make the necessary adjustments before the end of the programme.

Process evaluation of Total Sanitation Campaign in Orissa, India

The research team working on the Orissa Cluster-Randomised controlled trial, funded by Bill and Melinda Gates Foundation, has conducted a process evaluation of the implementation programme of latrines under the Total Sanitation Campaign (TSC). The TSC aims at providing latrines to households Below the Poverty Line (BPL). The aim of the process evaluation was to assess the programmatic intervention prior conducting a randomised controlled trial on the impacts of sanitation in the areas. From the beginning of implementation and for 12 months the research team has conducted monthly visit to the intervention villages. The following activities were conducted:

  • Assessment of level implementation registers, maps and records
  • Meeting with village water and sanitation committee
  • Site inspections and checklist of each phase of planned implementation

Process evaluation of the National Sanitation Campaign in Tanzania

The Environmental Health Group in collaboration with the Ministry of Health and Social Welfare, the Ministry of Education and Vocation Training, DFID Tanzania and WSP/World Bank is conducting a process evaluation of the National Sanitation Campaign in Tanzania. The NSC, launched in June 2012, is coordinated by the Ministry of Health and Social Welfare (MoHSW) and involves NGOs, the private sector and other government ministries.

The evaluation is designed and coordinated by Rick Reinghans and Elisa Roma from SHARE consortium. Its main objective is to rigorously assess the implementation of the National Sanitation Campaign and whether this is likely to catalyse the expected changes, at both household and school level. Furthermore, the evaluation aims to assess the enabling environment and the level of unit costs spent in the NSC to identify potential strategies or steps that have been done or could be done to increase the efficiency of the campaign. The evaluation will be characterised by three main components: a) a household survey, b) school WASH survey and c) evaluation of the enabling environment and of the costs necessary to achieve expected results. The evaluation will cover rural households and schools across the 14 regions of Tanzania.
