The 2016 Aid Transparency Index uses 39 indicators grouped into weighted categories, to assess how transparent donor organisations are about their aid activities. These categories cover overall commitment to aid transparency and publication of information at both organisation and activity level. Within the publication category, the organisation-level indicators account for 25% of the overall weight, while the activity-level indicators account for 65%. The two publication groups are further divided in subgroups, based largely upon the subgroups used in the Common Standard implementation schedules template. The subgroups are equally weighted.
