validity assessments

Validity assessments evaluate whether a test or measurement genuinely measures what it claims to measure. For example, if a test is designed to assess math skills, validity checks confirm that the test truly reflects math ability and not other factors like reading skills. There are different types, such as content validity (covering all relevant topics), construct validity (measuring the right concept), and criterion validity (correlating with other similar measures). By assessing validity, we ensure the results are meaningful and trustworthy for decision-making or research purposes.
