Academic ranks in the Netherlands are the titles, relative importance and power of professors, researchers, and administrative personnel held in academia.
Personal chair are becoming increasingly familiar; and are generally promoted from the assistant or associate professor ranks in a department.
Professors emeriti have no formal teaching or administrative duties and are paid no salaries (instead they receive pension payment).
In any event, professors who move out of the academy or retire in good standing retain the ius promovendi.
Since the change in the law in 2018, in some universities the ius promovendi is granted to the UHD1 rank or individuals with a proficient track record to be primary supervisor of a PhD project.
From 2018 onwards, the law has changed and holder of a position with a research university appointment (effectively an experienced UD or UHD or a (senior) researcher who has a doctorate) is eligible to be main supervisor of a PhD student.
[3] Universities have agreed that only such colleagues with proven capacity to supervise PhD projects will be granted this right.
[4] Increasingly, Ph.Ds are co-supervised by a UD or UHD, and they are often the regular point of contact for the Ph.D. student, particularly in large research groups.
Although the ranks are often translated as if they were aligned with the American system (i.e. assistant, associate, and full professor), this not as clear-cut.
Based on salary pay grade, lectors would rank between associate and full professor in the research university system.
