The objective of this research study was to identify the factors affecting the professional characteristics of teacher educators by comparing two models of teacher education. The research findings revealed four major focal points that have an impact on professional characteristics: the operational model adopted by the institution where teacher educators work; the breadth and depth of teacher educators' research and scholarship and the degree to which such scholarship is required as part of the assessment criteria; the cooperation between the training institution and the practical field (i.e., the schools where the students do their practice teaching); and the informal relationships between teacher educators and their students. The novelty of the study resides in the fact that these points affect teacher educators' professional characteristics and that focusing on these characteristics facilitates a comprehensive view of methods, tools and directions that may expedite the professional development of teacher educators.
