Although the structural model provided by the University of Paris, where student members are controlled by faculty "masters," provided a standard for universities, the application of this model took at least three different forms. There were universities that had a system of faculties whose teaching addressed a very specific curriculum; this model tended to train specialists. There was a collegiate or tutorial model based on the system at University of Oxford where teaching and organization was decentralized and knowledge was more of a generalist nature. There were also universities that combined these models, using the collegiate model but having a centralized organization.
