Participatory assessment of development (PADev) guidebook

Available languages

Participatory Assessment of Development (PADev) is an approach to impact evaluation that radically moves away from a focus on a single agency, project or programme. It takes a particular area as point of departure and reflects -through different groups of people- on interventions that have taken place and what has changed over a period of time (typically 20-30 years).

PADev is a bottom-up assessment based on the value systems of the population in the area. Best and worst interventions are selected and their benefits are analysed over time. The assessment uses a range of instruments to collect qualitative and quantitative data and pays particular attention to data quality. make it possible to do various qualitative and quantitative analyses. Recommendations for various types of analyses are included.

The guidebook is open source: further experimentation and adaptation is encouraged. All instruments, field reports and primary data are available on
