This article examines the process and outcome of a life design counseling group intervention with students in Grades 9 and 12. First, we applied a quasi-experimental methodology to analyze the intervention’s effectiveness in promoting career certainty, career decision-making, self-efficacy, and career adaptability in a sample of 236 students. Second, focus groups comprising 33 participants were conducted, examining participants’ perceptions of the intervention process and outcome. Our findings

showed that the intervention had a significant effect on both career certainty and career self-efficacy, but it had no effect on career adaptability. Our results also showed that My Career Story (MCS) had a stronger effect on Grade 12 students. Focus group participants reported on the usefulness of MCS, as well as on its benefits, which include increased information as well as a sense of direction, self-discovery,

connection, and increased self-awareness. Grade 9 participants expressed more difficulties in narrating self-experience than Grade 12 participants did. Implications for future research and practice are discussed.
