This research aims to develop a strategy for various maintenance works inside buildings, whether planned, emergency, or remedial maintenance, with the aim of preserving the building and increasing its operational efficiency. The applied study also examines the impact of the proposed strategy on the efficien-cy of operating schools, with the aim of preserving them and increasing the life span of the building. The applied study dealt with choosing one of the schools as a study sample, which is a secondary education school that was chosen to un-dergo a comprehensive planned program of maintenance under the supervision of the Educational Buildings Authority and the Directorate of Education, where the goal was to rehabilitate the structure for work instead of complete replace-ment with total demolition. Therefore, it was chosen as a study sample and a form was applied. And monitoring and evaluation schedules designed for that school to demonstrate the suitability of the proposed maintenance strategy for application in cases of similar schools, with the aim of making recommendations to decision makers when carrying out comprehensive maintenance of a similar school with the aim of raising its efficiency and rehabilitating it. The goal is to develop a methodology for managing maintenance work to increase the effi-ciency of operating the school building as one of the important types of build-ings, with the aim of providing spaces and spaces qualified for basic pre-university education.
