Recommended Reports During Measure Testing
A measure developer should develop specific reports when testing a measure (or set of measures). Although completion of reports usually occurs after beta testing, measure developers should consider the need to report the results of formative alpha testing, especially if the intent is for alpha testing to precede beta testing. The first few steps of measure testing address planning and execution of testing and are identical for alpha and beta testing; the last steps address reporting and follow up after the conclusion of testing.
During measure testing the measure developer
- Develops the testing work plan
- Performs sampling
- Implements the plan
- Analyzes test results
- Refines measure, including incorporation of stakeholder input
- Retests the refined measure
- Updates the measure documentation
