Although there are many studies examining deeply the relationship between the ability to write and the process-based writing approach in the world, it has been found that there was no a thematic analysis study in this scope in Turkey. When considered from this aspect, it is clearly seen that there is a need specifically in Turkey to present the impact of the process-based writing approach studies on the development of writing skill. In this study, which aims to examine the process-based writing approach in a comprehensive framework, quantitative and qualitative studies conducted in the relevant literature have been evaluated by the thematic analysis method. According to the findings of the study, it was concluded that the students’ current writing skill success levels and attitudes towards writing in general were low. Furthermore, it was found that in the studies conducted by taking into consideration the process-based writing approach, this approach improved the students’ success in writing and attitudes towards writing. It was thought that this was the most important result of the research. However, it is seen that conducting writing studies with process-based writing approach positively affects writer identity. It is seen that students' writer identity is conceptualized in terms of the purpose of writing, opinions about the author, writing process and writing proficiency. As a result of this research, it is thought that using process based writing approach in teaching writing is useful.
