This toolkit, developed by REL Northeast & Islands for use by schools, districts, and states (and other groups serving them), helps practitioners learn the purpose of logic models, the different elements of a logic model, and the appropriate steps for developing and using a logic model for program evaluation. This toolkit provides a complete workbook and slide deck for two sessions. Session I is 120 minutes long, and Session II is 90 minutes long. The first session focuses on the elements of a logic model and the process for developing a logic model for a program or policy. The second session provides guidance on how the logic model can be used as a tool to develop evaluation questions and indicators of success.
