The present research aims to analyze the deficiencies in the old buildings of the educational institutions of the Comas district; the government has put its interest in reducing the gap in the educational infrastructure in a complementary way in which preventive and corrective maintenance actions are carried out, while school construction follows a cumbersome path. This delays the investment required in schools and universities. The methodology is based on the percentage variations of the schools by levels; for this, a sample of educational institutions was considered, based on critical components such as basic infrastructure, essential services, and advanced infrastructure, deficiencies in basic infrastructure were analyzed, verifying that this is a significant indicator that heralds quality and safety. Hence, it is crucial to work on the replacement of educational infrastructure. The results showed that, in the period 2017-2020, the percentage variation was 7.5% for initial education; meanwhile, for primary education, it was 3.61%, and for secondary education, the percentage variation was 7.14%.
