The article is devoted to the experimental study of the formation of language analysis skills in modern children with varying degrees of severity of writing disorders. 98 subjects studied the skill of text and sentence analysis, syllabic and phonemic (sound) analysis for 3 years. In parallel, during the period of study in the first and second grade, children’s writing skills were studied. In the future, the formation of all types of analysis in children with varying degrees of severity of writing disorders in all periods of study was analyzed. The article may be of interest not only to speech pathologists, primarily speech therapists, but also to preschool teachers and primary school teachers.
