Findings from research indicate that teachers participating in online professional development (OPD) activities and programmes have gained, in some way or another, a great deal of teacher competency. In spite of this, no research has been undertaken to systematically identify and acknowledge the types of teacher competencies that are frequently associated with and attributed to OPD. This paper, based on findings from other studies and literature reviews, attempts to initiate and explore the above vacuum. A literature analysis, using a simple tool based on the coding strategies, is used to categorise the types or aspects of teacher competencies that were evident. The results indicate five major aspects: (1) motivation; (2) skills, knowledge and ideas; (3) self-directed learning; (4) interactive competence; and (5) computer technology awareness and skills.
