What is a logic model and what are its core components?

• A. A logic model depicts the pathway from inputs to activities to outputs and outcomes to impact, including assumptions and external factors.
• B. A logic model is a statistical model for predicting disease incidence.
• C. A logic model is a budgeting tool with no outcomes.
• D. A logic model is a policy analysis framework with no environmental factors.

Answer: (A)

A logic model is a clear map of how a program is supposed to create change. It shows the sequence from the resources you invest (inputs) to what you do with those resources (activities), what you produce for participants (outputs), the concrete changes you expect in the short and medium term (outcomes), and the ultimate effects you hope to achieve in the long term (impact). It ties these elements together with the program theory—the ideas about why the activities will lead to the desired changes—and it accounts for external factors and context that can influence whether the change occurs. This structure helps you plan what to measure, when to measure it, and how to judge if the program is moving toward its goals. This is why this choice is best: it captures the full pathway from resources to impact while acknowledging the assumptions and environmental context that shape success.
