Because most previous studies employed TAM to examine users' willingness to use information systems, this study further considered the characteristics of the dropout notification and return to school system and incorporated other assessment variables into the proposed model in order to enable the system to provide a better explanatory model. The research results show that effectiveness and interactivity of the system indeed had significant positive influence on user attitude. Comparing to the original technology acceptance model, this proposed educational information system integrated model will be able to better explain users' behavioral intentions toward using the dropout notification and return to school system
