The Good Life Careers Personality Instrument© is based on the personality theory of Carl Jung. It is modeled after the Myers-Briggs Type Indicator (MBTI) and the Keirsey Temperament Sorter, with specific emphasis on career development. Results are reported as personality peferences with 16 possible types. Results generally are consistent with the Myers-Briggs Type Indicator (adults) and the Murphy-Meisgeier Type Indicator for Children (children).

For children aged 9 to 12 years, parents answers the items about their child. Children certainly can particpate in answering the questions with their parents. The Instrument measures personality differences that are equally healthy and valuable ways of perceiving the world and behaving. There are no "right" or "wrong" answers. The Instrument typically takes less than 15 minutes to complete.
