The quality of data published in IATI XML is assessed by running a series of tests on all activity and organisation data packages being published to the Registry. These tests have been designed to assess the availability and comparability of aid information and to determine whether an organisation’s IATI data conforms to the IATI Standard appropriately. Most of the tests have been derived directly from the IATI schemas which provide formats for reporting data on various information fields to the IATI Registry. The tests return results for the percentage of activities within an organisations’ data packages that contain correctly coded information on the specific indicator being tested. For example: what percentage of activities reported contain a title? Or what percentage of activities that have been completed contain information on results?
