Document Summary

Something is valid if it is sound, meaningful, or well grounded on principles or evidence. Validity: judgment or estimate of how well a test measures what it purports to measure in a particular context. How useful instrument is for a particular purpose with a particular population of people. Test is shown to be valid for particular use with a particular population of testtakers at a particular time. No test or measurement technique universally valid for all time, all uses and all types of testtaker populations. Tests valid within what we characterize as reasonable boundaries of contemplated usage. Validation: the process of gathering and evaluating evidence about validity. Validation studies: research that entails gathering evidence relevant to how well a test measures what it purports to measure for the purpose of evaluating the validity of a test or other measurement tool. Classic conception of validity referred to as trinitarian view.
