A DISCUSSION PAPER FOR 3IE’S MEMBERS. by Rick Davies, July 2011. Commissioned by the Office of Development Effectiveness, AusAI. Available as pdf.
The purpose of this discussion paper is to inform AusAID’s and other 3ie members’ engagement with 3ie (the International Initiative for Impact Evaluation). It precedes the forthcoming evaluation of 3ie, and is more limited in scope. It is expected to be complementary and useful to the larger Department for International Development (DFID) study now underway, Developing a broader range of rigorous designs and methods for impact evaluations, as the author of this report is also a member of that study team.
AusAID is a member of 3ie and provides core funding to 3ie to contribute to the global public good of policy-relevant evidence on what works in development. Direct benefit to AusAID is not the purpose of the membership. However, it is important to AusAID that 3ie’s work is relevant to AusAID’s partners, particularly partners with low income and/or in fragile countries. AusAID’s Office of Development Effectiveness (ODE) manages AusAID’s membership of 3ie and has commissioned this discussion paper.
The focus of this discussion paper is on 3ie methodological approach, used in both the funded impact evaluations and systematic reviews, and how this has changed over time.
