This chapter describes the technological profile of foreign language (FL) teachers from Modern Languages university courses of the state of Paraná, Brazil. Several features were investigated: teachers' personal characteristics, teachers' beliefs and attitudes towards technology, teachers' digital literacy, teachers' prior CALL/ technology education and Rogers' (1995) adopter categories. The theoretical framework used was the Diffusion of Innovations theory. A quantitative methodological approach was employed to collect data and a survey questionnaire was developed. Statistical analyses examined the relationships between attitudes and digital literacy, adopter categories and attitudes, adopter categories and personal characteristics. The results provided a detailed picture of the ones responsible for the education of future FL teachers in Brazil. With this technological profile, it was possible to reveal the “who” in the process of CALL integration.
