Comprehensive Adolescent and Adult Personality Test using the Five Domains


The NEO Inventories provide a comprehensive and detailed assessment of personality that is well-established and respected.  The NEO-PI-3 is:

  • A measure of all five dimensions of personality: Agreeableness (A), Conscientiousness (C), Neuroticism (N), Extraversion (E), and Openness to Experience (O). 
  • Suitable for clients ages 12 and over including middle school-aged children and adolescents, as well as adults with lower educational levels.  
  • Administered in under 40 minutes.
  • The NEO-PI-3 is a modification of the NEO PI-R in which 37 of the 240 items have been replaced. The new items are easier to understand and have better psychometric properties.


Features and benefits

  • Can be administered orally to individuals with limited literacy or with visual problems.
  • Demonstrated utility in clinical, applied, and research settings.
  • Useful in vocational counseling, pre-employment screening, and educational psychology.
  • Components include:
    • The NEO Problems in Living Checklist (NEO-PLC), a tool for clinicians to assess problematic behaviors and symptoms.
    • The NEO Style Graph Booklet, a way to provide feedback to respondents.
    • The NEO Job Profiler, a tool to identify traits relevant to an occupation or position
  • The two-part carbonless hand-scorable answer sheet eliminates the need for separate scoring keys or templates.
    • Form S (for self-reports) consists of a series of items answered by respondents to describe themselves.
    • Form R (for observer reports), is a companion instrument with parallel items written in the third person for peer, spouse, or expert ratings. Form R can be used to obtain independent estimates on the same five domains of personality and may be of particular value in instances when it is desirable to validate or supplement self-reports.
