For students graduating from upper secondary school (menntaskóli), Iceland’s closest equivalent to US high schools, celebrations begin on the last day of classes, when students on the verge of graduation celebrate their dimmisjón (also spelled dimmition or dimission, from the latin dimissio). Dimmisjón traditions differ between schools, but celebrations usually last all day and can include breakfast with teachers, school dinners, and house parties. Most notably, classes or friend groups decide on a group costume, and spend the afternoon cavorting down Laugavegur street dressed as animals, objects, or movie characters. Though Iceland’s legal drinking age is 20, it is rumoured that dimmisjón celebrations involve a few glasses of alcohol.
During the graduation ceremony, graduating students put the costumes away. There’s not a robe in sight but most students wear student caps. These are black caps with a black band and peak, decorated with a silver star. During graduation, menntaskóli students wear the cap covered in a white crown. One year after graduating, graduates remove the white cover and many wear their black cap to subsequent graduation celebrations.
Different versions of the student cap have been introduced next to the traditionally white-coloured crown. Students graduating from vocational education specialising in, for instance, trades, agriculture, or the fishing industry, use red and green instead.
