The field of social work transformed over time from providing relief to less fortunate individuals to a sophisticated profession that looks at evidence-based measures to deliver change. This has been possible by looking at accountability aspects to demonstrate improvement by addressing performance outcomes resulting from interventions. Outcomes operate on all levels from micro to mezzo to macro, and the skills needed include identifying who is being served and the specific goals to be achieved. This article introduces the use of a logic model as a way to explain interventions and outcomes on a short-term, intermediate term, and long-term basis. The section also describes current measures being used to demonstrate how outcomes are used to justify the practice.
