The aim of this study was to examine elementary school students' story writing skills according to grade level within the framework of certain variables. The study was designed with a cross-sectional research model, one of the developmental research methods. The study group of the research consisted of 319 students attending 4th, 5th, 6th, 7th and 8th grades. A Story Writing Form developed by the researchers was used as the data collection tool in the research. In the data collection process, the students were given the story writing form and asked to write a story within a certain period by choosing one of the topics included in the form. To evaluate the stories written by the students, the 6+1 Analytic Writing and Assessment Scale was used. The research results revealed that the great majority of students used a title in their stories and that they created their stories with a single paragraph. On the other hand, it was seen that the grade level and gender variables had an effect on the quality of the stories. Generally, the quality of the stories improved as grade level increased, and girls wrote better quality stories than boys. However, this effect was not significant at every grade level.
