The Aid Transparency Index aims to push donors to publish their aid and development information in an open data format. As the global aid landscape changes and donors make progress towards this goal, the methodology has been revised and developed to remain relevant. The Aid Transparency Index methodology was revised for the 2013 Index and again for 2018, 2022 and 2024.
The 2024 Index features some changes to the index methodology. Following a review of the assessment method, we have updated and re-issued the technical paper incorporating these adjustments.
The 2024 Aid Transparency Index technical paper contains a full account of the scoring system and indicator definitions.
More details of the methodology, scoring and indicator definitions are given on the methodology page
