This study examines two models of knowledge sharing. Model 1 investigates the association of willingness to share knowledge, ability to share knowledge and knowledge sharing. Model 2 tests the individual’s effectiveness as an integration term of willingness to share and ability to share with knowledge sharing. The final sample of this study consists of 204 accounting students at Umm Al-Gura University for the academic year 2013/2014. Using a survey-based methodology, the multiple regression of Model 1 shows that the willingness to share and the ability to share knowledge are associated positively with knowledge sharing. In addition, the result of the simple regression of Model 2 illustrates that individual’s effectiveness was positively associated with knowledge sharing. The results of this study are useful for educational policy makers in Saudi Arabia and elsewhere, as there is an opportunity of enhancing the knowledge sharing in the educational context.
