摘要：The study examined the influence of information system (IS) characteristics namely; system quality, information quality and service quality derived from the extended DeLeon & McLean (2003) IS success model, in addition to the influence of a hypothesized technological/infrastructural factor on postgraduate (PG) students satisfaction of the University of Ibadan (U.I) postgraduate (PG) school web portal. The study was a descriptive survey of PG students of the University of Ibadan. A sample of 385 students were selected using proportional stratified sampling technique. A self structured questionnaire was used to collect data from the study respondents. Data was analyzed using descriptive and inferential statistics. The result shows that all the information system characteristics; system quality (β = 0.380), service quality (β = 0.223), information quality (β = 0.153), and technological /infrastructural factor (β = -0.111) in that order, significantly (p<0.05) influenced postgraduate students satisfaction of the web portal. The study recommends the need for the university to implement an IT policy that will ensure efficient management of the information system, in addition to large scale investment in internet infrastructure to maximize users satisfaction.
