What Is a Logic Model?
A logic model is a simple diagram that communicates the rationale for why a program will work. Also known as a “theory of change”, a logic model shows how contextual factors and programmatic inputs, activities and outputs are related leading to the program’s desired outcomes. Since over 30 counties have implemented Linkages in California, a commonly accepted logic model has evolved for this initiative. Click on the links below to view two different versions of the Linkages logic model: one from the overall system perspective and the other from the staff and families perspectives.
Why Create a Logic Model?
A logic model is a useful planning tool that helps programs clearly connect resources and activities to results. Logic models are also valuable tools for communication, evaluation, and continuous learning and improvement. Consider using the Linkages logic model to:
- Communicate the purpose, rationale and key elements of Linkages.
- Show why Linkages is important.
- Create a common understanding and reference point for everyone involved in Linkages.
- Illustrate what will result from Linkages and how to achieve these results.
- Ensure that you have the necessary resources (inputs) for Linkages.
- To define what success means for Linkages to inform evaluation.
- Reference when you are designing training materials and evaluation tools.
- Revise as you learn from implementing Linkages and from evaluation feedback.
If you decide to proceed with Linkages in your location, follow the steps in the Evaluation Road Map to customize the Linkages logic model so that it reflects the context, substance and results planned for your specific Linkages program.
