The present research investigates academic social climate in architectural studies as perceived by students. It studies the importance that the various measures of academic social climate have in the studio and in architectural classes. It also investigates the relation between the personal background of students and their sense of academic social climate. Academic social climate is evaluated with regard to the eight factors proposed by Moos (1979) dealing with: orientation to study material, innovation, academic social connections, teachers' support, competitiveness, academic-social involvement, order and organisation, teachers' control and an index for general academic social climate by means of a survey. Findings show that academic social climate was higher in the studio than in the regular classes in social connections, students' involvement, teacher support, and order and organisation; while academic social climate measures were higher in the regular classes in teacher control and in the orientation of learning material. The highest academic social climate measures in both studio and classes were students' involvement and competence, and the lowest measures were teacher support, and order and organisation. Some items of students' personal and educational background were found to affect their sense of academic social climate. The implications of these findings for architectural design education are presented.
