Research in the field of well-being among Flemish students in secondary schools has shown that age is an important predictor of well-being. What is the impact of school infrastructure on the well-being of students in Flemish secondary schools? A study, commissioned by AGIOn (the Flemish agency that subsidises school buildings), investigated the impact of educational spaces on their users and set out to identify empirical evidence supporting the importance of school infrastructure on the well-being of students in secondary schools. The research team found empirical evidence to support the importance of school infrastructure on the well-being of students in the Belgian region of Flanders. Previous international research indicated that the subject was significant; this research takes it a step further by offering tentative findings on effects and tendencies. Although the present research has some limitations and more work is required in order to refine their findings, the authors hope nevertheless to have contributed to the body of scholarly research on the subject.
