This study adds to the literature by emphasizing an organizational perspective from the viewpoint of students in the sphere of higher education, especially within a developing-country context. The limitations are a cross-sectional design, reliance on self-reports, and data collected from just one geographical region only. Future works should incorporate a longitudinal design, with further explorations into other mediators such as motivation or institutional reputation.This study explores the interrelationships between perceived service quality, perceived organizational climate, and organizational citizenship behavior (OCB) in Libyan universities. It focuses on how students view their institutions for higher learning with respect to quality of services and how such perception is influenced by organizational climate and mediated by OCB, using a quantitative approach to data collection. Structured questionnaires were administered to a sample of 409 students drawn from two universities—one public and the other private—in Tripoli, Libya. The constructs were measured using adopted scales: service quality with SERVQUAL, organizational climate with Terzi's scale, and OCB with Organ's framework. Statistical analyses including regression and mediation, following Baron and Kenny's methodology, were run via SPSS. The findings indicate that perceived organizational climate is significantly and positively related to OCB and service quality. Furthermore, OCB mediates partially in the relationship between perceived climate and service quality, which implies that voluntary beneficial behaviors in students are conducive for an increase in the service quality facet of higher education.SERVICE QUALITY AND PERCEIVED CLIMATE
