'Old-style' PhD candidates
PhD candidates at the faculty of IDE who started their PhD project before September 1st 2011 are not officially part of the Graduate School. Following Doctoral Education is recommended for them, but not formally required.
Many of the rules for Doctoral Education and progress meetings are different for these candidates. But each of them gets a PhD mentor assigned, and is welcome (of course!) at the events that GS-IDE organizes. For details on regulations regarding 'pre-GS' candidates see this page. For other questions, ask your PhD mentor.
