Prior actions are reforms that are required for Board approval of the loan and operation. They are designed to address important constraints on the achievement of the operation’s development objectives. This rating assesses the extent to which prior actions: (i) addressed meaningful constraints or had a major impact on the achievement of the project development objectives (PDOs), and (ii) made a substantive and credible contribution to achieving those objectives. In rating the relevance of prior actions, the IEG evaluator will attempt to: (i) ascertain the clarity and credibility of the results chain linking prior actions to the achievement of the objective, taking into account the adequacy of the analytical basis linking the prior action to the PDO (and lessons learned from similar operations or experiences in the particular client country or in similar countries), and (ii) assess the importance of prior actions to the achievement of outcomes. This approach is expected to result in more operationally relevant lessons.
