Doing a PhD in The Netherlands
Being a PhD candidate in The Netherlands is different from some other countries. First of all, PhD candidates are not students; they are actual employees, with a salary and social benefits. To become a PhD candidate, you therefore apply for an open position rather than enrol in a programme. A PhD trajectory can start at any time in the year, not just at the beginning of the academic year.
An appointment as a PhD candidate is typically for three or four years. The PhD candidate is expected to produce a PhD thesis in this period, which consists of at least four research chapters. These chapters are first-author publications in leading international journals. At least two such publications must have been published or accepted before the PhD defence can take place.
