Logic models are used to describe important components of a program and link activities to intended outcomes. For the purposes of monitoring and evaluation, a wellconstructed logic model directly informs the selection of specific questions to be addressed; discussion of data needs; and translation of findings to real-world recommendations for improvement. The workshop addresses two key questions: (1) What are the hallmarks of a well-constructed, scientifically-sound, and useful logic model? (2) How do we maximize the use of high-quality logic models for monitoring and evaluation planning, implementation and use of findings?
