The paper presents the results of the research conducted with students in the first year of the Early Childhood and Preschool Education graduate study programme at the Faculty of Teacher Education, University of Zagreb. The aim of the research was to examine future preschool teachers' experiences with English in their daily use and in preparing their theses and to gain insight into their plans for future professional development. The results showed that future preschool teachers use traditional sources of knowledge, such as books, textbooks, scientific and professional journals, and other types of texts and tools, such as news articles, Google Search and similar engines, and social networks. In addition, it was determined that almost half of the respondents do not plan to use academic texts in their future careers as primary forms of lifelong learning and professional development.Although the respondents evaluated their media literacy, information literacy, and command of English with high marks, they had difficulty critically evaluating the reliability and credibility of academic, journalistic, and AIgenerated texts in English.
