ECG's Good Practice Standards (GPS) for the Evaluation of Public Sector Operations aim mainly to: (i) establish standards for the evaluation of interventions made by international financial institutions (IFIs) that meet good evaluation practices generally accepted in the evaluation literature and backed by the experience of ECG members; and (ii) facilitate the comparison of evaluation results across ECG members, including the presentation of results in a common language. The GPS also attempt to define more effective linkages between independent and self evaluation; improve the identification and dissemination of best practices in evaluation; and improve the sharing of lessons from evaluation. The standards are applicable to projects supported by IFI investment loans, technical assistance loans, and policy-based lending.
GPS on public sector operations first were adopted in 2002. In 2007 the ECG members agreed to update the GPS to reflect the evolution of evaluation practices and to allow some flexibility in implementation. The work was completed in 2011.
