This chapter describes an experience in teacher training for e-learning in the field of adult education. It takes into account the models offered by flexible lifelong learning as the proper way to develop training for teachers in service, considering the advantages of blended learning for the target audience. The chapter discusses the balance between mere ICT skills and pedagogical competences. In this context the learning design should always allow that the teachers in training integrate in their work ICT solutions that fit to the didactic objectives, renew teaching and learning methodology, facilitate communication, give place to creativity, and allow pupils to learn at their own pace. By doing so, they will be closer to the profile of a tutor online, as a practitioner who successfully takes advantages of the virtual environments for collaborative work and learning communication.
