Course enrolment
The course enrolment procedure for all GSLS Master’s courses is as follows (for Epidemiology (Postgraduate) see the Epidemiology website):
- Prerequisite knowledge and placement rules are clearly described for each course in OSIRIS. Contact GSLS Course Information (Biomedical Sciences) or Hans Luijendijk (Biosciences) for changes.
- Students can register via OSIRIS Student for a course during the corresponding course registration period (see table below).
- The course coordinator can download from OSIRIS the registration list of students that have applied for their course after the registration deadline. See instructions for this below ‘How to register students from the waiting list’.
- When admission to a course requires additional information, e.g. a motivation letter, this must be clearly described in the course description in OSIRIS. Students will need to email the information separately to the course coordinator before the registration deadline.
- The course coordinator determines which students are admitted to the course and sends the placement list to the administration offices within two weeks after the registration deadline (preferably in an Excel file). Please arrange replacement in case of absence.
We advise that placement is done in the following order of priority:- Students from own Master’s programme for which the course is mandatory (make sure that the capacity is sufficient);
- Other students from own Master’s programme;
- Other GSLS students;
- Other students, including PhD-students;
- Students on the low-priority list. (They did not deregister on time, did not show up or withdrew last-minute without a valid reason. They will be placed with the lowest priority for course registration in the next period by the administration office.)
In case of capacity issues, it is advised to place students from category 2 to 5 by lot. This can be done automatically via the administration office.
- The administration office enters the list of accepted students in OSIRIS.
- Students that have been admitted to the course and do not want to participate in the course have to deregister before the deregistration deadline (see table below).
- Courses will be re-opened for the late enrolment period. The course coordinator determines which of the re-registered students are admitted to the course, as described above, and sends the placement list to the administration office within 1 working day after the late enrolment period.
Please note:
- Administration offices are responsible for the course enrolment procedure. Please forward students with questions about course registration and admission to the administration office of their faculty.
- For questions, contact the administration office.
