This paper of CEDIL examines the current state of each of the waves (outcome monitoring, impact evaluation, systematic reviews and knowledge brokering) of the evidence revolution. The paper offers a critical perspective on each wave, and discuss the implications for evaluation in the field of international development. Whilst the use of evidence has grown, underuse and misuse remain. More importantly, there has been a failure to institutionalize the use of evidence beyond the intervention level. The last part offers some concluding comments.
