This document presents a methodology for evaluating the contribution that communication interventions can make to accountable governance. CommGAP engages in complementary programme areas in an effort to amplify citizen voice; promote free, independent, and plural media systems; and help government institutions communicate better with their citizens. The three programme areas are: research and advocacy; capacity building and training; and support for development projects. This document describes the evaluation framework - that is, the outcome and impact indicators, and the methodology behind the assessment - that CommGAP has developed.
