The measure developer should use the results of measure testing to demonstrate a measure’s alignment with most measure evaluation criteria. Because testing is an iterative process, both alpha and beta test findings may provide information addressing measure evaluation criteria.

• Alpha testing often supplies information demonstrating feasibility of the measure’s implementation.
• Measure developers may use the findings from one or more beta tests to demonstrate scientific acceptability and usability and use, as well as to augment previous information on the importance and feasibility of the measure.

Explore how to apply testing to four measurement areas—importance, scientific acceptability, feasibility, and usability and use. See the Measure Evaluation Report and Instructions for additional guidance.
