Program evaluation is a systematic method for collecting, analyzing, and using information to answer basic questions about projects, policies and programs[1]. Program evaluation is used in the public and private sector and is taught in numerous universities. Evaluation became particularly relevant in the U.S. in the 1960s during the period of the Great Society social programs associated with the Kennedy and Johnson administrations[2][3]. Extraordinary sums were invested in social programs, but the impacts of these investments were largely unknown.
Program evaluations can involve quantitative methods of social research or qualitative methods or both. People who do program evaluation come from many different backgrounds: sociology, psychology, economics, social work. Some graduate schools also have specific training programs for program evaluation.
(b) Logic Model
The logic model is a general framework for describing work in an organization. Since work is often packaged in programs, it is often referred to as the program logic model.
In its simplest form, the logic model analyzes work into four categories or steps: inputs, activities, outputs, and outcomes. These represent the logical flow from:
- inputs (resources such as money, employees, and equipment) to
- work activities, programs or processes, to
- the immediate outputs of the work that are delivered to customers, to
- outcomes or results that are the long-term consequences of delivering outputs.
The basic logic model typically is displayed in a diagram such as this:
INPUTS –> ACTIVITIES OR PROCESSES –> OUTPUTS –> OUTCOMES
