Participatory Assessment of Development (PADev) is a holistic method of evaluating development and social change. Local people assess the impact of a large variety of development initiatives on their lives, their capabilities and their environment. PADev enables local history writing, using a variety of gender, age and location-specific perspectives. The method helps to assess the impact of development initiatives on locally perceived groups of relatively rich and relatively poor people in the society. This guidebook offers a host of insights and suggestions and hopes to add to practices of self-evaluation and bottom-up history writing.
