Career assessment methods often include measures of individual differences constructs, such as interests, personality, abilities, and values. Although many researchers have recently called for the development of integrated models, career counseling professionals have long faced the challenge of integrating this information into their practice. The authors examine the use of integrated models to enhance the career counseling process, including Armstrong, Day, McVay, and Rounds's (2008) RIASEC-based Atlas Model of Individual Differences (using Holland's 1997, typology of 6 interest types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional [RIASEC]) and Armstrong, Smith, Donnay, and Rounds's (2004) basic interests-based Strong Ring. These models provide a structured framework for presenting clients with assessment feedback that emphasizes connections between interests, personality, and abilities. resenting trait complexes or constellations for use in career counseling and other applied settings. An alternative interest-based model, the Strong Ring (Armstrong, Smith, Donnay, & Rounds, 2004), has also been proposed using basic interest measures.In this article, we examine the recent calls for integration, highlighting the potential utility of integrated models when working with career counseling clients who are making educational and career-related decisions. We then examine two interest-based models proposed by Armstrong and his colleagues, the Atlas Model of Individual Differences (Armstrong et al., 2008) and the Strong Ring (Armstrong et al., 2004), that are part of this emerging movement, and we consider how these models can be used to integrate individual differences measures when working with career counseling clients who are making academic and career-related decisions. Finally, we provide a theoretical underpinning for these integrated models by drawing on recent developmental research by Denissen, Zarrett, and Eccles (2007), Hogan's (1983) Socioanalytic
