The population included second- to fourth-year undergraduates, data from a sample of 600 were collected through a structured questionnaire using stratified random sampling and analyzed using structural equation modeling (SEM). Design/methodology/approach: The aim of this study is to examine the various dimensions of academic staff quality that affect student satisfaction within a selected private higher educational institute in Sri Lanka, providing a clear understanding of the dimensions of academic staff quality and recognizing the important role of the said dimensions in shaping the educational experience of the students. Findings: Results revealed that effective support for students, lectures’ broader knowledge, quality of delivery and quality of evaluation were significant predictors of student satisfaction and that they are crucial indicators of how strong the impact of the academic staff is in contributing to overall undergraduate student satisfaction. Originality/value: This study filled a gap in higher education research in Sri Lanka by offering empirical evidence on the impact of academic staff quality on satisfaction among students in private universities. It serves as a valuable reference for those exploring higher education concepts, providing a novel understanding of the influence of the key component of academic staff quality.enAcademic staff qualityEffective support for studentsHigher educationLecturers’ knowledgeQuality of deliveryQuality of evaluationStudent satisfactionArticlehttps://doi.org/10.1108/JARHE-12-2023-0562
