Teacher educators play an important role in preparing student teachers to integrate technology into their classrooms. This article presents an overview of research literature on teacher educators' competences in preparing their students to teach with technology. A literature search yielded 26 relevant research articles. Four domains of competence were identified: technology competences, competences for pedagogical and educational technology use, beliefs about teaching and learning and competences in professional learning. The literature focuses on teacher educators’ competences in using technology for teaching. Research on the competences that teacher educators need and have as second-order teachers is lacking. Recommendations for future research are discussed. •Literature on teacher educators' competences as role models is scarce.•Four domains of competence for teacher educators can be identified.•Most research focuses on competences to teach with technology.•Research on teacher educators' level of competences is limited.
