This paper discusses the duality between global perspectives and local realities that have influenced the design of the school architecture by examining and comparing state school projects in two geographically distant countries: Chile and Portugal. The proposals and experiences of the "Society for the Construction of Educational Facilities" (1937-1987) in Chile and the "Board of Constructions for Technical and Secondary Education" (1934-1969) in Portugal are analysed. Established in the 1930s, these centralised bodies managed, organised, and controlled state school building projects in such a way as to achieve uniformity in design, creating architectural identities that embodied both the educational values and the representative character of the State. These bodies were influenced by similar global circumstances, and their activities were guided by the recommendations issued by intergovernmental organisations of the time. Such a situation brought their projects closer together in terms of their functional, aesthetic, technical-constructive characteristics. After examining and identifying the international influences which brought them closer in terms of the educational meanings and values associated with school architecture, the paper identifies the local circumstances that guided the design and construction processes of schools in both countries, bringing fresh geographical insights to school architecture discussion. At the same time, possible global readings of strategies, influences and results are explored, enabling us to understand school architecture as part of a nation's cultural values and as a material expression of the social model of modernity, which will continue to meet the challenges that schools face in twenty-first-century society.
