Indicators used and scoring approach

The Aid Transparency Index uses 39 indicators, divided into those that measure commitment to aid transparency (three indicators) and those that measure publication of aid information (36 indicators).

The commitment indicators collectively account for 10% of the overall weight while publication accounts for 90%.

The publication indicators are further assembled into organisation level and activity level, which are then divided in sub-groups. These are based largely upon the groups used in the implementation schedule template for the Busan common standard.

The organisation-level indicators account for 25% of the overall weight, while the activity-level indicators account for 65%.

Within these categories, the indicator sub-groups are equally weighted. As the number of indicators in each sub-group varies, individual indicators carry different weights. See full list of indicators and how they are grouped and weighted. The re-weighting tool allows users to test different weighting options and see the effect on the scores.

The score for each indicator ranges from 0–100. 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.
