A tour of the work of Miguel Fisac in the educational field in which he carried out 14 projects between the years 1944 and 1962 of different dimensions and all of them within the context of the 1953 law. Projects both commissioned by the Ministry of Education and different religious orders, that are a sample of the evolution of educational thought in our country and the conception of the project by Fisac. From among them we have selected five unique projects: the Daimiel Labor Institute, the Madrid Teacher Training Centre, the Valdepeñas Institute, the Núñez de Arce Institute in Valladolid and the Colegio de la Asunción Cuestas Blancas in Madrid. Three of them are already included in the DOCOMOMO registry. An example of the use of constructive solutions and the functional organization of the proposed programs that allows three of them to continue with their initial educational uses. Proposals that, with the adjustments to new regulations and necessary maintenance adjustments, continue to be excellent references for the school architecture of those times.
