Student discount applies to high school students and students up to and including 34 years. If you are a student under 20 years old, child ticket is cheaper.
You must have a valid student ID from your school in Norway that shows the current semester, valid Norwegian student ID and term card from higher education, or ISIC card.
A valid student ID must have the name, date of birth, place of study and show what semester it is valid for. One tip is to download the app Student ID from Google Play or App Store, or the app Pocket ID from Google Play or App Store.
Adult foreigners up to and including 34 years who undergo the course "Norwegian with social knowledge" or the introduction program for refugees, receive student discounts. Valid ID and student certificate with name, date of birth, valid semester and stamped picture must be submitted upon request.
Remember that you must be able to show that you are entitled to a discount upon request. Without valid proof of discount, you will receive an additional fee in a ticket inspection.
