In today's context, teachers not only teach, but also help to develop students to become useful citizens. The principles of transformational learning require teachers to change their beliefs, behaviours and emotions. At the end, teachers should be able to reflect on their experiences to help students holistically and thus this article will help to provide comprehensive overview of transformational learning among teachers. The scope of this review paper covers articles written between 2015 and 2020. Among them are peer coaching, implementation of adaptive change models (ACM), conflict, training, service learning pedagogy and approaches relating to culture. Previous studies have shown that transformational learning theory can enhance teacher effectiveness and bring about dissemination of changes. Therefore, there is a need to explore the relationship and the inconsistencies between Mezirow's transformational learning theory and that of teaching theories practised by teachers. It is noted that most studies show significant relationships between the two theories but some studies claim that they are not significant. It is hoped that this study will be of benefit to practicing teachers to develop balanced and harmonious people.
