NCE Counseling And Helping Relationships Practice Test

Validity in testing is best described as:

The extent to which a test measures what it is intended to measure. The stability of scores when retaken. The degree of agreement between two independent raters. The breadth of test content across domains.

Correct Answer:

The extent to which a test measures what it is intended to measure.

Explanation:

Validity is about whether a test actually measures the construct it claims to measure and supports the inferences drawn from the test scores. It focuses on accuracy of measurement and ensuring that the test’s results reflect the intended attribute, rather than something else. In contrast, reliability asks whether scores are consistent across time or raters, which is about stability and agreement rather than whether the test assesses the right thing. The breadth of content speaks to how much of the domain the test covers, not directly to whether it measures the intended construct. So the statement that describes validity best is the one that defines validity as the extent to which the test measures what it is intended to measure.
