Types of Evaluation

There are three basic types of evaluation:
  1. Process evaluation
  2. Outcome evaluation
  3. Legacy (post-program) evaluation
Process evaluations ask "what happened?" These take place as a program evolves and is generally for the purpose of improvement. As a program is created, process evaluation would be used to assess the need for such a program or determine what form it should take. It is also used once a program is underway to assess:
  • Inputs—how resources are being used
  • Outputs—how well activities are carried out and whether they involve and reach the intended audience
This enables you detect the strengths and weaknesses of the program while it is in progress and make program improvements.

In contrast, an outcome evaluation generally asks "did it work?" It is used to determine whether things worked as planned and whether changes can be attributed to the program's activities. Assessments of a program's efficiency or cost-effectiveness compared to outcomes are also types of outcome evaluations.

A legacy evaluation takes place after a program has finished. It is used to determine the program's long-term outcomes or ultimate impact—such as changes in health status—which may not be detectable until a program has been around for a while or has ended.
