Introduction Outcome Evaluation

Outcome Evaluation is the examination and assessment of a program’s effectiveness. This form of evaluation helps
us understand if there is evidence to suggest a program is causing change in the desired impact or outcome.
Impact or outcome assessments of program effectiveness are most useful when attempting to demonstrate whether
a program seems to be working.

To conduct such an assessment, data should be collected in order to demonstrate that there are observed
changes in the program’s population. An assessment of program effectiveness is often conducted using
quantitative methods and is usually characterized as the program’s outcome evaluation. The quantitative method
most commonly used is surveys (pre- and post-tests).
