Project Evaluation at IDB and IDB Invest: Infoguide

This document outlines the project evaluation methodologies used by the Inter-American Development Bank (IDB) and IDB Invest to assess the success of completed projects. Central to this process are Project Completion Reports (PCRs) and Expanded Supervision Reports (XSRs), which evaluate performance across four core criteria: efficiency, sustainability, resilience, and effectiveness. In contrast to other multilateral development banks (MDBs), the IDB and IDB Invest use stricter verification protocols, evaluate projects against their design prior to implementation, and require full achievement and sustainability of outcomes to receive satisfactory ratings. Methodological differences such as the lack of intermediate ratings and limited flexibility for adaptation result in more conservative ratings compared to peers.
