According to the IDB’s independent evaluation office, only 53 percent of IDB sovereign projects in the latest validation cycle were successful in the four core areas of relevance, effectiveness, efficiency, and sustainability. This falls considerably short when compared to the World Bank's 80 percent achievement, or the approximately 70 percent achievement for both the African Development Bank and the Asian Development Bank. The IDB lags even further behind if we focus on effectiveness, where only 27 percent of projects achieve their expected results.
