Based on common aspects of recent models of career decision making (CDM), a six-phase model of CDM for secondary students is presented and empirically evaluated. The study tests the hypothesis that students who are in later phases possess more career-choice readiness and consider different numbers of career alternatives. Two hundred sixty-six Swiss secondary students completed measures tapping phase of CDM, career-choice readiness, and number of considered career options. Career-choice readiness showed an increase with phase of CDM. Later phases were associated with a larger increase in career-choice readiness. Number of considered career options showed a curve-linear development with fewer options considered at the beginning and at the end of the process. Male students showed a larger variability in their distribution among the process with more male than female students in the first and last phases of the process. Implications for theory and practice are presented.
