The article explores the integrative role of education and training in NATO’s initiatives on achieving interoperability. The research niche is NATO's quality assurance procedures in education and training as a mechanism for enhancing interoperability and strengthening defense capabilities. The study aims to assess the current implementation of NATO quality standards in Education and Training Facilities (ETFs) and justify the expediency of the accreditation procedures. The hypothesis is that existing quality assurance practices contribute to both the integration of various ETFs affiliated with NATO into a cohesive education area and the enhancement of the Alliance’s capabilities. The methodology combines a review of relevant scientific literature and NATO regulations with descriptive statistical analysis of data from the NATO Quality Assurance Hub and the Education and Training Opportunities Catalogue. Dialectical, formal-logical, and systemic-structural methods are applied to interpret the findings. The results indicate that NATO Education and Training Facilities and Centres of Excellence are at the forefront of implementing NATO quality standards. These institutions, designed to address the Alliance’s training needs, serve as core drivers of its strategic educational objectives. Rather than enforcing curricular uniformity, NATO’s quality assurance procedures enhance institutional management while upholding academic autonomy. Due to this, military education providers may also seek accreditations aligned with other international or national quality standards. The study concludes that NATO’s quality assurance procedures foster a unified training environment and complement other frameworks on interoperability. These efforts contribute to strengthening the Alliance’s joint capabilities by promoting the integration of partner countries into NATO’s security community.
