New information technology (new IT) plays an increasingly important role in the field of education, which greatly enriches the teaching means and promotes the sharing of education resources. However, because of the New Digital Divide existing, the impact of new IT on educational equality has yet to be discussed. Based on Information System Success Model (ISSM), this research introduces the user's ability access, including skills ability access and usage ability access, to explain the relationship between the new IT application and educational equality, and has carried on the empirical test using PLS-SEM statistical analysis techniques. The results show that the system quality, information quality and service quality of new IT would directly affect the user’s ability access, further affect user’s intention to use and user’s satisfaction, and then influence the realization of educational equality.
