Welcome to the first Annual Report for the International Aid Transparency Initiative (IATI). IATI has come a long way from the political commitment at the third High Level Forum on Aid Effectiveness in Accra in 2008, through to its launch in 2009, to the tipping point in 2012 that saw the 100th donor publish information (now over 130 publishers). The momentum surrounding IATI is encouraging and this is exactly where we would want to be at this stage. But we still have a long way to go. As well as reviewing progress to date, this report looks forward to future priorities. Now is the time to challenge each other on the quality of our IATI data, and to strive to improve quality, increase access and better use this growing and invaluable resource.
