This study proposes an integrative model of pedagogical strategies aimed at developing core competencies of primary school students. The model combines learner-centered approaches, active learning methods, individualized instruction, collaborative interaction, and formative assessment into a unified pedagogical framework. The research substantiates that the integration of these strategies creates systematic conditions for enhancing students’ cognitive, social, and communicative competencies. The integrative model emphasizes the coherence between instructional methods, learning activities, and assessment practices, ensuring learners’ active participation and learning autonomy. The findings demonstrate that the effectiveness of the proposed model depends on teachers’ professional competence and supportive educational environments, contributing to sustainable competency development in primary education.
