Indicators provide a signal to decision makers by indicating whether, and to what extent, a variable of interest has changed. They can be used at all levels of the results framework from inputs to impacts, and should be linked to the programme’s theory of change. Most important at the lower levels of the causal chain are monitoring indicators such as inputs (e.g., immunization kits supplied), activities (e.g., immunization days held) and outputs (e.g., clinics built). For higher-level indicators of outcomes and impact, however, monitoring tells us what has happened but not why it happened. To understand this, impact evaluation must be used to increase our understanding of the factors behind achieving or not achieving the goal.
