You should receive with your application the section for the department in which you expressed an interest. University degree requirements are described in full in the Stanford Bulletin . Many of the departments also have information about their programs and requirements on the web. See the Teaching and Research section of the Stanford Home Page for departmental web pages. The University minimum unit requirement is 36 units earned at Stanford as a graduate student.
Most departments have a higher unit requirement.
The residency requirement is three full-tuition quarters. At the discretion of the department, work done at another university as a graduate student, after conferral of the bachelor's degree, may be used to meet department requirements that exceed the 36 unit University minimum. However, the residency requirement of three full-tuition quarters is not reduced. The Educational Specialist Degree and the Engineer Degree require 45 units and three full-tuition quarters beyond the master's degree. Three quarters of residency for work done at another university as a graduate student may be applied to the residency requirement.
