Psychometric Properties

Psychometric properties are the quantifiable aspects of a test that indicate its statistical strength or weakness. Psychometric properties are intrinsic components of a test and reveal information about a test’s adequacy, relevance, and usefulness. Validity, reliability, and norming are fundamental psychometric properties of a test.

Psychometric properties of a test are associated with the data garnered from the assessment to determine how well it evaluates the interest construct. Psychometric properties often use numerical quantities such as a coefficient or an index for representation. The development of an excellent psychometric test depends on the extent to which it undergoes statistical analyses, which ultimately ensures that it has the required psychometric properties.
