A Primer on the Validity of Assessment Instruments

5. How is the validity of an assessment instrument determined? 4 – 7, 8 Validity of assessment instruments requires several sources of evidence to build the case that the instrument measures what it is supposed to measure.,9,10 Determining validity can be viewed as constructing an evidence-based argument regarding how well a tool measures what it is supposed to do.

In this test, a sample of approximately 200 granules encounters 100 particle–wall impacts per second with an adjustable impact velocity. The strength of the granules was thus determined by observing the breakage caused. Over the range of moisture contents tested, the granules have a maximum strength at a moisture content of between 0.20 and 0.25.
