When assessing the overall quality of a publisher’s data it is necessary to judge both breadth and depth. The Coverage dimension covered by this table assesses what proportion of an organisation’s total output is published through IATI. This is done by comparing a publisher’s total ‘IATI’ spend for a given year with an external source. This produces a Spend Ratio. As IATI is a multi-stakeholder initiative representing a range of organistion types there is no single source for this comparison: the OECD DAC provides comparison for DAC-reporting bilaterals; the UN System Chief Executives Board for Coordination reports UN agency expenditures; INGOs and foundations publish annual reports, usually with audited financial statements.
As it is impossible to create an exacting methodology applied to disparate comparisons, the percentage Coverage applied to the overall score uses a broader framework. The Spend Ratio will be adjusted using the following scale of coverage: Excellent: 80% or over (adjustment factor 100%); Good: 60 – 80% (adjustment factor 80%); Fair: 40 – 60% (adjustment factor 60%); and Poor: less than 40% (adjustment factor 40%).
The IATI technical team is still working on pulling these disparate sources together into a single table for use here. For the moment it is acting as a placeholder, with all publishers assessed at 100%.
