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 were first adopted in 2002. In 2007, ECG members agreed to update the GPS to reflect the evolution of evaluation practices and to allow some flexibility in implementation. Work was completed in 2011 and this revised edition was published in Feburary 2012.
