General scoring approach
The 2022 Index methodology uses 35 indicators to monitor aid transparency. The indicators have been selected using the information types agreed in the International Aid Transparency Initiative (IATI) Standard. The indicators represent the most commonly available information items where commitments to disclosure already exist. In addition, organisations’ overall commitment to aid transparency is measured by the existence of Freedom of Information (FOI) legislation or disclosure policies, plans for IATI publication and the organisation’s efforts to promote access, use and re-use of its information.
Groups and sub-groups
The 35 indicators are grouped into five weighted categories. Organisation planning and commitments to aid transparency account for 15% of the overall weight. Finance and budgets account for 25%. Project attributes, Joining-up development data and Performance are equally split and each account for 20% of the overall weight.
A graduated scoring methodology is used for some of the publication indicators. For 22 indicators, the scoring takes into account the format that the data is provided in, depending on the accessibility and comparability of the information and how consistently it is published. For example, information published in PDFs scores lower than information published in machine-readable formats. Information published to the IATI Standard, the most comparable format, can score up to 100 for each indicator, depending on the coverage of information and frequency of publication.
