The current research aimed to verify the psychometric properties of the writing skills scale for children with autism spectrum disorder. The study sample consisted of (50) boys and girls from the fourth, fifth and sixth grades of primary school, whose ages ranged between (9-12) years, with an average age of (10.30) years, and a standard deviation of (0.948). The experimental method was used. The results of the research showed that this scale has psychometric properties that make it possible to trust and rely on it. There are criteria that enable the interpretation of children's scores on it. The results confirmed the validity of using this scale to determine the level of writing in children with autism spectrum disorder.
