The Personality and Preference Inventory (PAPI) is a personality test which is used to determine a person's personality traits in the workplace. The questionnaire was designed to reveal a person's behaviours and preferences that may affect their suitability for a various vocations or specific vacant positions.[1] The test was originally designed by Max Kostick, Professor of Industrial Psychology at Boston State College, in the early 1960s. Since then, two versions of the test have been developed: the PAPI-I (Ipsative) for individuals and the PAPI-N (normative) for employers.[2] Although the tests are widely used, there is some scholarly debate over their accuracy and usefulness in comparing potential job candidates.[3][4]
