VCU is currently female students only but going co-ed this autumn I think. They have recruited a Qatari male to facilitate this.

Haynooh as a Muslimah myself I can with utter confidence say that it is not Islam which prevents co-ed, it is the culture of some families. Women and men can work beside each other in a respectful way in Islam which is how the world over does it.

Incidently I think Qatar Academy on the Qatar Foundation site has segregation of pupils at some point in high school.
