The Career Advancement Student Training Office (CASTO) at the University of Sharjah provides opportunities for enrolled students to work as part-timers within the campus through the Student Employment Program (SEP); it also builds a workforce that is ready to be called upon to serve the needs of the University community.

Students working part-time serve in a wide variety of positions on campus. The person answering the phone when you call a campus department is usually a UOS student working part-time. Those assisting you in the Admission Department Registration Department are also students working part-time. The organizing committees for conferences, workshops, and graduation ceremonies, and the individuals calling graduates to update information on the alumni database, all are also UOS students who are working part-time. The Sustainability Office hires SEP students to work on different projects and initiatives to enhance sustainability on campus.
