The document describes a transparency and good governance tool created by a Spanish development NGO platform. The tool consists of 76 indicators across 2 areas and 11 dimensions to measure transparency and good governance. Indicators are measured on a scale from 5-30 and given a relevance score. NGOs will undergo a voluntary self-evaluation process in 2009-2010, followed by a compulsory self-evaluation in 2011 and external audits starting in 2012. Key implementation issues discussed include the platform's role in oversight and accreditation, adapting the tool over time, and ensuring auditors objectively verify indicators rather than make subjective judgments.
