The Aid Transparency Index is the only independent measure of transparency among the world’s leading aid organizations. 


The 2016 Index is another opportunity to work closely together to improve aid transparency and meet the December 2015 Busan deadline. The list of organisations included in the 2016 Index has been revised to concentrate on fewer, larger donors, as well as those that have been instrumental to advancing the course of aid transparency. For this reason, the 2016 Index will include 46 donors, accounting for 98% of  ODF (Official Development Flows) between them.


The 2014 Aid Transparency Index came at a critical time in the push for open aid data. Donors promised to fully implement a common standard for publishing aid information – the International Aid Transparency Initiative – by December 2015. The findings highlight which donors are on- or off-track as we approach the agreed deadline. With just over a year to go, the clock is ticking.


The 2013 Aid Transparency Index used a revised methodology that reflected changes in the aid transparency landscape and the resulting need to assess the quality of published data better. The scores look at the accessibility and user-friendliness of the information, so the more open and comparable the information is, the more highly valued it is. Of the 67 organisations included in the 2013 ATI, 28 were publishing some current information in the common, open IATI format. MCC became the first U.S. agency to top the ATI.


For the 2012 Aid Transparency Index, 72 organisations were selected. As well as bilateral and multilateral agencies, selected climate finance funds, humanitarian agencies, development finance institutions and private foundations were included, in order to test the transparency of wider development flows. The ATI showed a gradual improvement in aid transparency, but found that most aid information is still not published. The average agency score in 2012 was just 41% – a modest 7 percentage point rise from 2011.


Our highly-regarded 2011 Pilot Aid Transparency Index was developed in direct response to the 2010 Assessment. The Index – the first of its kind – ranked donor agencies according to how much information they provided across 37 different indicators. The average score of 34% showed that although some donors had made progress, the majority needed to do much more. No donors ranked in the top category ‘good’, which required a score of over 80%.


In 2010, we produced the Aid Transparency Assessment, a comprehensive review of donors’ aid transparency. This assessment of 30 organisations demonstrated the lack of timely and comparable primary data provided by donors.
