Changes to course and exam enrolment: new ticket system and start date

8 July 2021

You will soon be able to enrol for courses and exams for the first semester of the academic year 2021-2022. Read here about two important changes to the process.


This information is not applicable to all study programmes and all students. The exceptions are:

New start dates

  • For bachelor’s students: from 15 July 13.00 hrs onwards
  • For master’s students: from 16 July 13.00 hrs onwards

Ticket system

Enrolment via uSis will work with a ticket system. This will monitor how busy it is and only be active when necessary. In this way we can prevent uSis becoming overloaded if too many students try to enrol at once.

How it works

  • When you go to uSis Selfservice, you will be placed in a queue.  
  • Once it’s your turn, you will have 10 minutes to log in. If you fail to do so, you will be put back in the queue.
  • Once you are logged in, you can enrol in the usual way.
Queue starts at 12.30 hrs

The ticket system will be activated at 12:30 hrs. If you are logged in before 12:30, you will automatically be logged out.

Enrolment via Leiden University app

There is no ticket system in place for enrolment via the Leiden University app. You can log in directly. However, be aware that the app may be slow if a lot of students try to enrol at the same time.

Prevent unnecessary queues

Try to avoid logging in at 13:00 hrs unless this is really necessary. In this way you can help prevent unnecessary busy periods and long queues.


Do you have any questions about the enrolment process? You can visit the Helpdesk Portal both before and whilst enrolling.

Ticket system for entire uSis Self Service

The ticket system is intended to help the enrolment process run more smoothly during peak periods. However, it will apply to the entire uSis Self Service area. This means that if you try to log into Self Service during a busy period, whether this is to enrol or for any other activity, the ticket system will be active and you will be placed in a queue.
