The advancement towards knowledge-based societies has modiﬁed the labor markets and qualiﬁcation requirements. In this sense, and considering that individual choices about careers and occupations have pervasive social eﬀects, there is a growing interest from both academics and policy makers in understanding and inﬂuencing the process of education choice. Speciﬁcally, there is a worldwide renewed concern on achieving higher levels of graduation from scientiﬁc and technological disciplines. Available evidence shows that mobilizing individual wills towards these highly priority careers is not an easy nor mechanical task. Thus, it is necessary to expand the standard view about the process of occupation choice by adding non pecuniary factors, inﬂuence of social networks and the role of information and guidance policies. With these ob jectives in mind, and after reviewing the theoretical literature about occupation choice in economics, the present paper analyzes the eﬀects that diverse personal, family, social and economic aspects have in the selection of an university career. Based on the empirical ﬁndings, some policy recommendations are put forward.
