The European Association of Architectural Education’s annual conference of 2019 was held at the Faculty of Architecture in Zagreb from August 28th to 31st. Titled ‘The Hidden School’, it aimed to open a discussion on the substance and quality of architectural education, an architecture school’s true character, the traits which – however explicitly or implicitly manifested – embody the school’s culture and identity. The conference explored the subliminal quality of architectural education less apparent just by reading the curricula or following evaluation procedures, yet which represent a substantial quality or the culture of a school, quite clearly legible to those engaging in it. The invitation to explore this topic proposed five aspects of a school as triggers, focusing on tacit meanings situated between the lines of the syllabus, the spirit generated by students contributing to it or the educators personifying it, informal learning modalities, spaces it inhabits: the Educator, the Content, the Process, the Place, the Student. The scientific committee placed a question to the participating schools: “If the hidden school exists in parallel or as a background process, a self-generated search for fundamental answers, and its interpretation, manifestation or legibility has a multitude of facets, how can these aspects be captured?” Is it possible to assess the ‘hidden’?
