In this 1-year longitudinal study, the authors explored the development of narrative skills between the oral and written form. The authors aimed to assess the predictive power of textual narrative competence on early narrative text-writing skills taking into account the impact of spelling ability. Eighty children ("M" age = 5.3 years, age range = 4.9-5.7 years; SD = 0.29) were followed longitudinally until entering the first grade of primary school. During kindergarten, they were tested with an oral story production task and in first grade with a written story production task. Narratives were evaluated in terms of structure, cohesion and consistency. In the first grade, children were also submitted to a dictation task to evaluate their spelling competence. Repeated measures ANOVAs were performed in order to examine narrative competence development, also considering gender differences, and regression analyses were implemented to evaluate the predictive capability of textual abilities expressed by oral narratives on textual abilities expressed by writing. The results showed some significant differences when scores in kindergarten were compared to scores in primary school. Moreover, the ability to tell well-structured, cohesive and consistent stories predicts the ability to write stories with the same qualities in the sample of participants without spelling difficulty. Instead, the predictive link is not apparent considering those children with difficulties in orthographic ability. This research allows us to reflect about how the medium of writing might interfere, on the basis of the level of mastery, with the opportunity to express narrative skills in the transition from the oral to written code. The central role of writing instrument functionality opens the way to practical implications.
