The purpose of this article is to analyze the theoretical and methodological foundations of organizing the educational process on an integrative basis using the Finnish experience and to identify its applicability in modern education systems. The study employed comparative-pedagogical analysis, conceptual analysis, pedagogical modeling, content analysis, and abstract-logical generalization. The findings indicate that the Finnish model of integrative education is based on interdisciplinary connections, project- and research-based learning, the study of real-life problems, and formative assessment. This methodology contributes to the development of students’ complex thinking, critical reasoning, independent learning competencies, and problem-solving skills. The study concludes that adapting the Finnish experience to the national education system can serve as an important scientific and practical basis for improving the quality of education and effectively implementing a competency-based approach.
