The sudden change in the learning process during the Covid-19 pandemic has brought schools at all levels to adopt e-learning. In this study, we analyze user acceptance of NUADU platform in private schools in Balikpapan, Indonesia. The extended Technology Acceptance Model is used as a reference model. The study results indicate that facilitating conditions have a significant effect on perceived usefulness. All core constructs of TAM have a significant effect except the relationship between perceived ease of use and attitude and perceived usefulness and behavior. Based on these findings, recommendations are then made to strengthen the acceptance of NUADU platform.
