Exploring Program Evaluation: Measurement

Measurement, Reliability, and Validity in Program Evaluation

When evaluating programs, it is important to pick some closest to the intent of the program intervention. Behavioral changes or reliable measures of behavior from other sources would often be ideal but other instruments to measure changes in attitudes, knowledge, or self-reported behavior would be alternates.

Reliability and validity are also important for program evaluations, including but not limited to, instrument reliability and validity. The author should include information about them in the reports.
