ICT is a term that refers to a wide range of services, applications, and technologies. In search of new formative practices and scenarios, governments and international organizations have called for their inclusion at different educational levels. However, various circumstances have limited their expansion and caused problems that have hindered their progress. In this context, the aim of this study was to explore the impact of an ICT formative process through wikis on the beliefs, attitudes, and competences of a group of English teachers. The study used action research to describe and interpret the experience and involvement of the participants. Descriptive statistics and content analysis were combined to analyze the data collected through surveys, diaries, questionnaires, and interviews. Results indicate that English teachers must first focus on their ICT opinions, dispositions, and abilities before embarking on the development of technological practices and processes.
