The graduates will assemble 15 minutes before the ceremony starts in front of the ceremony hall. You can leave your belongings in room T-307 (the room will be locked for the ceremony).
What to wear?
As the ceremony is a formal daytime affair, wearing a (lighter, if possible) suit or a blazer with dress pants will be appropriate. When choosing a dress or a skirt and blouse combination it's good to keep in mind that plunging necklines or back cut-outs are more appropriate for eveningwear.
The guests will be able to enter the ceremony hall 15 minutes before the beginning. As the ceremony hall only fits a few hundred people, you can also tell your guests that the ceremony will be live broadcast in the Astra building lobby, on the 4th floor of Terra building (T-410) and in all the TVs on campus. In addition to that you can watch the ceremony online: www.tlu.ee/aktus.
The ceremony will begin with the procession (graduates and academic staff) which will be followed by the Estonian national anthem. After the speech and a musical interlude the diplomas will be handed out by programme: the names will be read out one by one. When hearing your name, you'll move forward to accept your diploma, then sign for it and receive a flower before moving back to your seat. The graduate's speech will be followed by everyone singing Gaudeamus (the lyrics will be handed out to your seat beforehand) and a procession out. The event will take ca 1,5 hours, the MA ceremony around an hour.
