Abstract: The school buildings condition is an important factor in influencing school learning environment. This study aims to contribute in establishing the actual condition of primary school buildings in Sarawak, Malaysia. It focuses on the relation of school’s age and building condition. The primary data is collected via building condition survey from 24 primary schools using Condition Survey Protocol (CSP) 1 Matrix and analyze via Statistical Package for Social Sciences. The school age is taken up as main parameter towards the analysis of number of defects, total marks and overall building condition. The analysis carried out found that 4,725 defects have been identified and the overall rating for all school is 9.71 which is at the fair condition. The findings proved that building age is closely related to buildings condition and it supported the prevalence theory that ‘the aging building has more defect than the new one’. This indicates that the maintenance mentality is still in traditional mode and remains unchanged. The finding could assist relevant parties to take appropriate action in improving school facilities condition.
