"Our goal is to enable more people and organizations to undertake and commission high-quality randomized impact evaluations and thus to build a wider and deeper evidence base on how best to combat poverty. Our hope is that we will see the generation and application of rigorous evidence grow even faster than in the past two decades. By innovating and testing and by feeding the evidence back into even more innovation, evaluators and practitioners can improve the effectiveness of policies and programs and make a real difference in people’s lives." (Glennerster & Takavarasha, 2013)
