This study examined the effect of insurgency on senior secondary school educational resource management in the northeast, Nigeria. The study adopted a descriptive survey research design using a population of 17,479 teachers, 363,156 students and 737 senior secondary schools. The sample size of 391 teachers and 400 students was determined using Yamane (1973) formula. The respondents were selected using a multi-sample sampling technique. The study was restricted to four Northeastern States, Nigeria (Adamawa, Borno, Gombe and Yobe) grossly affected by insurgents’ activities from 2014 – 2023. Insurgency and Educational Resource Management Questionnaire (IESMQ) with a reliability of 0.89 after content and face validation was used for data collection. Descriptive statistics of simple bar chart, mean and standard deviation were used to answer the research questions and any item found to be within the mean score of 2.50 and above was considered high, adequate and frequent while below 2.50 was considered to be low, inadequate and rarely. The study found that students’ enrolment as of the year 2024 stood 94,617 for Yobe, 74,890 for Borno, 69,739 for Gombe and 123,910 for Adamawa. The level of educational resource provision by State government and availability was found to be grossly inadequate in all of the States. The study also revealed that the maintenance of facilities was frequently carried out while the effect of insurgent activities on school attendance was high in the region. Based on the findings, the study recommended that the Federal and the State governments should increase funding, security provision and investment in rebuilding infrastructure in all the affected States in the region and equally develop workable strategies and measures to mitigate disparities in the provision and maintenance of educational resources in the area.
