What does "validity" refer to in the context of testing?

In the context of testing, "validity" specifically refers to the extent to which a test truly measures what it claims to measure or predicts what it is intended to predict. This means that if a test is designed to assess intelligence, for instance, validity evaluates whether the test accurately reflects an individual's cognitive abilities rather than measuring unrelated factors. High validity ensures that the outcomes of the test provide meaningful and relevant information about the construct being assessed.

For instance, a valid intelligence test would correlate with other established measures of intelligence, providing assurance that it is indeed evaluating cognitive capacity rather than other variables, such as educational background or socio-economic status. This aspect is crucial in psychological assessment, as it underpins the reliability and applicability of test results for making informed decisions or evaluations.

While consistency in results (the degree of consistency of test results) and the accuracy of scoring methods are important features of test quality, they are distinct from the concept of validity. Validity directly addresses whether the test is measuring or predicting what it is meant to, which is the core reason that option B is the correct choice.
