The College of Basic and Applied Sciences consists of 9 departments and two schools. Administratively and organizationally there is no difference in a department and a school. Each is an administrative unit centered around one or more related disciplines. Each department has a Chair and each School has a Director. These individuals are leaders in their department and serve as the administrative and budget head of the unit.
