Which component is not part of a logic model?

• A. Inputs
• B. Activities
• C. Randomization of participants
• D. Outputs

Answer: (C)

In a logic model, you map how a program uses resources (inputs) to carry out activities, which produce tangible products or services (outputs) that lead to desired changes (outcomes) within a broader context of assumptions and external factors. Randomization of participants is a research design technique used to assign people to groups to reduce bias in evaluation studies. It isn’t a labeled element of the logic model itself, which focuses on the program’s plan and the causal pathway from inputs to outputs to outcomes. Therefore, randomization does not belong to the standard components of a logic model.
