{{main|Personality test}}

[[Personality test]]s assess constructs that are thought to be the constituents of personality. Examples of personality constructs include traits in the [[Big Five personality traits|Big Five]], such as introversion-extroversion and conscientiousness. Personality constructs are thought to be dimensional. Personality measures are used in research and in the selection of employees. They include self-report and observer-report scales.<ref>Ashton, M. C., (2017). ''Individual Differences and Personality'' (3rd ed.). Amsterdam: Elsevier.</ref> Examples of [[Norm-referenced test|norm-referenced]] personality tests include the [[Revised NEO Personality Inventory|NEO-PI]], the [[16PF Questionnaire]], the [[Occupational Personality Questionnaires]],<ref name="psychassess" /> and the Five-Factor Personality Inventory.<ref>Jolijn Hendriks, A.a., Hofstee, W.K.B, & De Raad, B.

The [[International Personality Item Pool]] (IPIP) scales assess the same traits that the NEO and other personality scales assess. All IPIP scales and items are in the public domain and, therefore, are available free of charge.<ref>International Personality Item Pool.
