Despite the fact that vocational adolescents are in a disadvantaged position regarding their post-secondary high school routes, research has highlighted the resistant and innovative ways they set in motion so as to grapple with their estranging schooling experiences. Our article aims to contribute to this research area by focusing on how adolescents' narration of their schooling frames their life planning. In particular, we explore a major finding of our research--namely, their defending of vocational training--by means of the notion of ambivalent biographical identity. We argue (a) that today's adolescents do not openly reject vocational training, and they try to transform the unofficial skills and knowledge obtained in their cultures into official cultural capital capable of making them enter the job market and (b) that their life planning is tied up with a biographical identity formation through which they try to coherently reconcile their embodied cultures with the vocational qualifications they aspire to acquire.
