The measure of m-leaming success is important to understand the value of management actions and investment in m-learning. Focusing on technology aspects of m-learning, no research has been done in m-learning success factors from the user's perspective. The objective of this study is to investigate key determinants of m-learning success perceived by users. Potential determinants of m-learning success are inferred from the general characteristics of m-learning system, the literature in Information System (IS) success and expert interviews. The potential factors are grouped into system quality, contents quality and service quality. User satisfaction construct is used to measure m-leaming success. The questionnaire is used to assess the satisfaction of users who had recently purchased learning products from m-learning vendors. The data collected by questionnaire were analyzed to check the validity of constructs. Then hypotheses describing the relationships between the identified constructs and user satisfaction were formulated and tested.
