This evaluation was conducted between April and May 2011 and has attempted to document the chronology of the evolution of the WERU approach in Zimbabwe and then to evaluate the WERU covering the period 2008 to 2010. As this was not a pre-planned intervention programme with data collection or monitoring components built in it has been difficult to assemble verifiable indicators of past performance for comparison against preset targets. Consequently much of the evaluation has been subjective rather than objective and based on anecdotal evidence and direct observations by the evaluation team. Although this is not an ideal modality it has been possible to develop an understanding of the nature of the WERU and achieve an assessment of its performance against the prescribed DAC criteria. The Terms of Reference for this evaluation appear in Annex to this report.
