You should complete the form requesting Terminal Graduate Registration (TGR) status PRIOR TO completing 135 units of coursework.  For most students, this form should be submitted at the beginning of Winter Quarter of their fourth year in the program.  Quarterly tuition is reduced substantially for TGR students once this request is approved by the Registrar.  Please note that in addition to completing 135 units of coursework, your Advancement to Candidacy and Doctoral Dissertation Reading Committee Forms must be completed and approved prior to making a request for TGR status.
