Criterion validity focuses on which of the following?

Criterion validity is a type of validity that assesses how well one measure can predict an outcome based on another measure. It establishes a relationship between the test in question and an external criterion that is relevant and valid. This is often seen in predictive validity, where a test predicts future performance, and concurrent validity, where a test correlates well with a currently existing measure.

When considering the importance of this concept, understanding the ability to predict performance on another measure is key. It demonstrates that the test has practical applications in real-world scenarios, ensuring it can effectively assess what it is supposed to gauge in relation to another established standard or outcome.

In contrast, measuring theoretical concepts, assessing how well a test measures its intended construct, and the presence of detailed assessment criteria focus on different aspects of measurement—specifically, they deal more with content validity, construct validity, and assessment standards, rather than the predictive aspect that criterion validity specifically addresses.
