Which of the following is NOT a component of a logic model?

• A. Inputs
• B. Activities
• C. Outputs
• D. Measures of impact

Answer: (D)

Logic models map how resources and actions produce outputs and lead to changes for participants or systems. The standard components you’d typically see are inputs (the resources you invest), activities (what you do with those resources), outputs (the direct products or services delivered), and outcomes (the changes you aim to achieve, short- to long-term). Measures of impact aren’t a separate component in the basic model—they’re the metrics used to assess whether the outcomes occurred. In other words, you’d specify how you’ll measure success as part of the evaluation, but the model itself focuses on the flow from inputs through activities and outputs to outcomes. For example, you might have funding and staff as inputs, training sessions as activities, the number of trainees reached as outputs, and increased knowledge as an outcome; the measures of impact would be the tests or surveys used to determine if that knowledge actually improved.
