In this article we focus on the effects of career education and guidance among students (ages 12-19) enrolled in prevocational and secondary vocational education in The Netherlands. Our study included 3,499 students and 166 teachers in 226 classes in 34 schools. The results showed that career competencies positively contributed to learning motivation, experienced quality of study choice, experienced fit of choice with learning tasks, and experienced fit of internship. Career identity positively contributed to career outcomes, and career dialogue contributed more than traditional interventions have with respect to career outcomes.
