This article presents a brief analysis of teacher education in five European countries: Italy, Germany, England, Sweden and Finland. In the post-industrial world, the sense of teaching has profoundly changed, influenced by a rapidly evolving socio-economic context. The responses given by each country are different, but two tendencies emerge: on the one hand, the English model, which seeks to make a teacher a faithful executor with regard to centrally decided learning objectives; on the other, the Nordic model that conceives the teacher as a "fully-fledged" professional. From the point of view of the sustainability and of the safeguard of the educative mission of the school, the second model, though with all the difficulties that its efficacious realisation entails, presents some advantages when compared to the first. The article concludes with some considerations on the need to conceive the reform of teacher education from a systemic point of view, in the context of a global change of national school systems, where the autonomy of the single schools plays a role of paramount importance.
