The logical model.
A logic model is the first step in evaluation. It helps determine when and what to evaluate so that evaluation resources are used effectively and efficiently. Through evaluation, we test and verify the reality of the program theory - how we believe the program will work. A logic model helps us focus on appropriate process and outcome measures.
