The IDA Results Measurement System (IDA RMS) tracks results in countries supported by IDA. The World Bank Group (WBG) introduced the RMS with the IDA13 Replenishment (July 2002) as a key reporting and accountability tool for tracking progress and reporting results achieved by IDA during each replenishment cycle. It was the first framework with quantitative indicators to monitor aggregate results established among multilateral development institutions. The IDA RMS is a central part of the WBG’s framework for tracking progress at an aggregate level and integral to the Bank’s efforts to improve the focus on results. The IDA RMS uses a three-tiered development results framework with 84 indicators to track results of IDA countries at an aggregate level.
