Ex-post evaluation

The ex post evaluation of PPPs involves the two steps summarised in the chart below.


A sound evaluation of a PPP project requires the public sector to:

  • identify the public body that will undertake the review of a particular PPP project;

  • ensure the independence of that body vis-à-vis the teams responsible for implementing and managing the PPP contract; and

  • define the questions that need to be answered in the evaluation exercise.

The rest of this section describes these aspects and the rationale behind them in more detail and suggests relevant examples of ex post evaluations for further reading.
