Purpose - The purpose of this study is to explore the determinants of teachers' continuance intention concerning cloud services. Design/methodology/approach - This study uses a cloud service, namely, Google Sites, to support teacher collaboration and further develop a research model to explore the determinants of their continued usage intention. Findings - The findings reveal that continued intention to use the cloud services is primarily determined by their attitude towards using it; attitude towards using is affected by perceived ease of use and perceived usefulness; and perceived ease of use is influenced by facilitating conditions, while perceived usefulness is influenced by social influence. Practical implications - This study determines that teachers intend to continue using cloud services once training in using such services has been provided and if they hear favourable opinions from others. Originality/value - The paper enables us to better understand factors affecting teachers' continuance intention toward cloud services.
