Self-appraisal is a major component in career maturity. Forty-six men and women completed the Career Maturity Inventory, the Temperament and Values Inventory, and rating forms that required self-estimates of the characteristics purportedly measured by the Temperament and Values Inventory. Self-appraisal was defined in terms of difference scores between self-estimates and Temperament and Values Inventory scale scores. Pearson correlations of the difference scores and each of the six Career Maturity Inventory scales (with coefficients corrected for attenuation by measurement error) provided strong support for the proposition that self-appraisal is a function of career maturity.
