Lots of innovations have been introduced into our lives with the 21st century. They offer great affordances and are benefited in every sphere of life. On the other hand, these innovations change our habits, including our teaching/learning habits. Therefore, actors in educational environments, especially teachers, have to keep pace with such changes, which requires being competent in the use of technological devices. Starting from this point of view, this study attempts to find out how Turkish teachers of English are doing in this process, and if such variables as their sex, age, what level they teach, whether they teach at a private or state institution, how long they have been teaching, and the duration of time they spend in technological environments affect their perceived technology proficiency. Survey research method was used, and data was collected via the Technology Proficiency Self-Assessment Questionnaire for 21st Century Learning (TPSA C-21) (Christensen & Knezek, 2017) from 273 participants. The results indicate that the participants' gender, age, years of teaching experience and what level they teach do not affect their perceived technology proficiency while how much time they spend in technological environments and whether they teach at a public or private school do.
