This document discusses key concepts in program evaluation including definitions, logic models, and measuring outcomes. It defines evaluation as the systematic collection and analysis of information about program activities, characteristics, and outcomes to improve effectiveness and inform decisions. A logic model framework is presented showing how evaluation examines inputs, outputs, and outcomes. Outcomes are then defined as changes in behaviors, skills, or other factors, while indicators are specific measurable observations that represent achievement of an outcome. The importance of measuring outcomes to assess a program's impact and identify areas for improvement is also emphasized.
