The NEO Inventories provide a comprehensive and detailed assessment of adult and adolescent personality that is well-established and respected.

Features and benefits

  • The NEO-PI-3 is a revision of the revised NEO Personality Inventory (NEO PI-R), the standard questionnaire of the five-factor model. In addition to measuring the five major domains of personality (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness), the NEO-PI-3 gives insight into the six facets that define each domain.
  • Retaining the reliability and validity of the NEO PI-R, the NEO-PI-3 features new normative data. A total of 38 items from the NEO PI-R have been revised or edited to lower the reading level and make the instrument more appropriate for younger examinees or adults with lower educational levels.
  • The two-part carbonless hand-scorable answer sheet, usable with either Form S (for self-reports) or Form R (for observer reports), eliminates the need for separate scoring keys or templates. Completed scannable answer sheets can be sent to PAR for scoring and interpretation, or they can be used with the On-Site Scanning Module of the NEO Software System. The NEO-PI-3 also can be scored and/or administered electronically using the NEO Software System.
