What’s the idea?

Whether you are planning to implement an intervention or are thinking about how to carry out an evaluation, it is essential to have a clear understanding of what you are trying to do. A logic model is one way to help you do this.

What does it mean?

A logic model graphically illustrates and provides a framework for the components of an intervention in terms of inputs, outputs and outcomes.

  • Inputs represent the resources that are put into the intervention: money, time and skills.
  • Outputs are what is done: the activities associated with the intervention and who it reaches.
  • Outcomes are the changes and benefits which accrue in the short, medium and long-term. For example, change in teacher knowledge and skills, application in the classroom and improvements in student learning.

What are the implications for teachers?

  • Understanding. Developing a logic model will give you a greater understanding of what needs to be done to make the innovation work, and at the same time gives you a framework for evaluation.
  • Alignment. Logic models help you to align activities and effects. By developing a logic model for an intervention it can help you spot those intended activities with no supporting activities and resources, and then make the suitable adjustments.
  • Supporting the collaborative planning process. The development of a logic model is an iterative process developed by colleagues working together. This can help build a shared understanding of what needs to be done to make an intervention work. It is also helpful when you are looking to disseminate an intervention within or between schools.
  • Accountability and outcomes. In schools where resources are increasingly scarce, a logic model can keep a focus on the outcomes of an intervention and on whether the planned for outcomes are actually happening.
