The document summarizes the history and development of the Career Maturity Inventory (CMI) test. It was originally constructed in 1973 by John Crites to assess career maturity. It has since undergone several revisions, including the development of Form C in 2011 to measure career attitudes and competencies using Savickas' theory of career construction and the four C's of concern, confidence, curiosity, and consultation. The CMI is used to help students develop career decision making skills and provide targeted career counseling interventions for low scores in the four C areas. While it has demonstrated validity in measuring career maturity constructs, some studies found modest reliability compared to earlier versions.
