This paper examines factors influencing post-adoption expectations toward an e-learning system. Following the expectation-confirmation based information system continuance theory, we use perceived usefulness as the surrogate of post-adoption expectations. Then, we propose a research model based on the prior literature where we hypothesize a number of factors along with the confirmation of initial expectations affect perceived usefulness. The model is tested among the university educators (n = 175) who use an e-learning system to conduct their teaching. The results suggest that post-adoption expectation is driven by confirmation of initial expectations, perceived control beliefs, and perceived system quality. Subjective norm does not have significant impact on post-adoption expectations. The determinants of perceived usefulness explained 68% of its total variance.
