This article explores the use of action research practices in developing writing skills in the context of Kazakh language teaching. Action research is grounded in a reflective, cyclical process: planning, acting, observing, and reflecting which empowers teachers and learners to co-construct knowledge and improve learning outcomes through systematic inquiry. The study aims to identify effective pedagogical strategies for enhancing academic writing competence by integrating action research into classroom practice. Drawing on practical cases from real school settings, the article highlights how teacher-led interventions impact students’ writing development and simultaneously support teachers’ professional growth. Special emphasis is placed on collaborative learning, formative assessment, self-correction, and critical reflection components that have been shown to enhance students' engagement and autonomy in language learning. The article also addresses the challenges of implementing action research in the local educational context and discusses its relevance for teaching Kazakh as a national language.
