This paper investigated how pupil and staff assessments of their school environment changed after extensive rebuilding had been carried out. The paper focused in particular on how the type of building work carried out was related to differences in pupil and staff assessments. Three schools were selected that reflected the different types of building work (ranging from a newly built school through to major refurbishment of an existing school). Using a questionnaire, data was collected from both S4 pupils and staff regarding their assessment of the new physical environments and the impact on their behaviour. All the new school environments showed significant improvements in staff and pupil assessments, however, the greatest improvement was for the new build and the least improvement for the refurbished school. Pupil assessments were generally more positive than staff assessments. Possible reasons for these differences are discussed.
