This two day event, which took place in Berlin on March 19th and 20th, was organised by Open Knowledge and facilitated by FabRiders. It aimed to strengthen the ability of data trainers to evaluate the impact of their trainings and share learnings with peers based on those evaluations. Ultimately the event aimed strengthen the quality and impact of data trainings provided to individuals engaged in social change work. “What I’ve Learned about Impact Assessments” is FabRiders’ blog post about the event.
