University drop out is a serious worldwide problem. A statistical model was used to explain the discontinuation of university study. The overall discontinuation rate over the five year period was 12%, with the Faculty of Science and Technology having a higher discontinuation rate than the other faculties. There was no evidence of a dropout difference between Muslim students entering university from Islamic high schools and those coming from public high schools. The students discontinued most in their first or second year of study. Five primary causes of dropping out were: concerns about being enrolled in a non-preferred field of study, security, lifestyle, problems with time management, and problems caused by a break or change in an intimate relationship. With the purpose of reduce the discontinuation rate, the guidance before entering the university and during studying in the university could be more informative in effective ways.
