Personality Type Inventory For Professionals (PTI-Pro)

Personality Type Inventory (PTI-Pro) is based on Carl Jung`s famous ‘Type Theory of Personality’ proposed through his book ‘Psychological Types’ published in the Gregorian year 1921. Hundreds of tests have since been developed on this theory including MBTI® (Myers Briggs Type Indicator), Keirsey Temperament Sorter, Golden Personality Type Inventory, Jung Type Indicator etc. Type theory is one of the most popular theories of personality used in business and it provides a very different approach to understand personality and human relations.

PTI-Pro is the latest among all the professionally developed tests and it takes advantage of the several years of research put into measuring and using personality type and work. Unlike other tests, PTI-Pro does not simply provide the most suitable type assessment but also provides a clarity index in terms of percentage (no other type based test provides clarity percentage). In addition to this, it comes with several different types of reports so that the test administrator can download the most suitable report as per the purpose of the assessment. It also has used some innovative methods of measuring personality type which yields greater accuracy and test-retest reliability.

Type Theory Based Personality Tests are not suitable for recruitment and selection as they are semi-ipsative and have high level of face validity.
