Cornerstone Economic Research developed the methodology for conducting performance and expenditure reviews (PERs) in 2012. Using this methodology, in 2013 the National Treasury, in partnership with the Department of Performance Monitoring and Evaluation in the Presidency, initiated a series of PERs of selected public programmes or policies, of which CER conducted the six reviews presented on this page. For further information, and to see PERs carried out by other parties, please go to the GTAC website. Click here to download a description of the PER methodology.
