ENThe aim of this article is to test the teacher leadership initiated by teacher professional development abroad, as a factor of organisational change in a structural equation model. Structural equation modelling was employed to analyse survey data collected from 218 teachers who participated in professional development activities abroad under Erasmus+ KA1 in 32 Lithuanian schools. The model expresses the relationship between teacher leadership and organizational change, where teacher professional development abroad is treated as an initial (self-development) dimension of teacher leadership. Results revealed the positive and significant relationship between teacher leadership and organizational change, where leadership is conceptualized as an ongoing relational process of self-development, dispersing ideas, involving others and gaining commitment. Findings of the study also depicted a positive and significant relationship of didactic competence (the dimension of self-development phase of leadership) with one of the dimensions of organizational change - learning in the classroom.
