This four-page brochure summarises lessons learned from the “Rights Education Action Programme” (REAP) about multipliers. REAP is a human rights education initiative led by Amnesty International Norway and implemented for ten years in ten countries around the world. These lessons are: using the multiplier approach in human rights education reaches and engages an exponentially greater number of people, and so increases impact; assessing human rights education methodologies and impact is important to developing accountable human rights education, and to measuring success; involving partners and participants in a framework for monitoring and evaluating human rights education work improves the results of assessments and integrates lessons learned into current and future work.
