The evolution and spread of PRA (Participatory Rural Appraisal or Participatory Reflection and Action) and CLTS (Community‐Led Total Sanitation) have involved activities of sharing and co‐generating knowledge which can loosely be considered a form of Action Learning. Key activities for this have been sequences of participatory workshops which have evolved as creative collective experiences fed by and feeding into wider networking and dissemination. These workshops have been occasions for sharing practice and collating experiences, and going beyond these to generate ideas and evolve and agree principles and good practices. Critical reflections concern power, planning and process, theory of change and impact, lessons learnt, and an ongoing learning process.
