This conceptual review examines the multidimensional linkages between quality assurance on academic and administrative service resulting to postgraduate student satisfaction in business school contexts. Recognising the complexity of actual service delivery in higher education, the study synthesises insights from Expectation Disconfirmation Theory (EDT) and the SERVQUAL model to construct an integrated conceptual framework. The proposed framework delineates five core service quality dimensions that collectively influence postgraduate students’ evaluative perceptions and overall satisfaction with their academic experience. By consolidating the key elements of theoretical perspectives, the review highlights a structured foundation in explaining core views on academic and administrative service delivery mechanisms shape satisfaction outcomes in postgraduate business education: perceived price value, student learning environment, employee commitment, assurance, and empathy. Through a systematic synthesis of seminal theoretical foundations and recent empirical studies across diverse higher education contexts, this paper advances theory-driven propositions explaining how postgraduate students form satisfaction experiences by aligning their actual expectations with perceived academic and administrative service quality. By explicitly integrating EDT with the SERVQUAL framework, the review offers a distinct theoretical contribution that extends satisfaction formation mechanisms beyond traditional consumer environments and conceptualises postgraduate students as active evaluators of complex educational services. The proposed integrated framework provides strategic implications for business school leaders and administrators by identifying key service quality dimensions that can strengthen student satisfaction, improve resource prioritisation, and cultivate sustained postgraduate student experiences and loyalty comes with an increasingly competitive learning environment landscape. Overall, the study enriches higher education marketing and service management scholarship by offering a theory-informed and contextually grounded explanation of postgraduate student satisfaction and loyalty.
