Maintenance involves the repair and maintenance of all facilities that belong to a particular organization or system to currently acceptable standard and to sustain utility and value. In other words, it is the act of keeping and or restoring the functional state of properties and services therein to sustain utility and value. There are lofty facilities and developmental projects delivered by successive administration in Nigeria, but such facilities are abandoned because of lack of regular maintenance that could guarantee the life span of the facilities for sustainable development. The lack of and poor maintenance culture has remained a bane to sustainable development in Nigeria occasioned by corruption, attitudinal problem, unfavourable government policies and diversion of funds meant for project implementation that incorporated maintenance policies. The system theory was adopted, applying the Systems Theory to maintenance culture and sustainable development; people are seen as parts or subsystems that make up the society and the sum total or collective intrinsic attitude of these individuals influences and defines the societal attitude. The study used descriptive survey research method as it research design. A ten item questionnaire called Maintenance Culture and Sustainable Development Questionnaire (MCSDQ) was used for data collection. A sample size of 284 was used, while simple percentage, age and frequency tables as statistical method for analyzing and interpreting the responses from the questionnaire were used along with the Chi-square () to test the formulated hypotheses for this study and determine the effect Maintenance Culture and Sustainable Development in Nigeria: A Study of Selected Government Secondary Schools in Ikot Ekpene LGA of Akwa Ibom State. Findings of the study revealed amongst others that lack/poor maintenance culture in Nigeria, characterized by neglect of public infrastructure and facilities, severely hinders sustainable development by causing rapid decay of assets, high replacement costs, and increased operational inefficiencies.
