Studentsamskipnaden SiO is an organization that offers a range of services to students in Oslo. It collaborates with 27 universities, and students who have paid semester fees at these institutions can make use of the offers. SiO has a varied service offering that includes student housing for individuals, couples and families, as well as health services such as doctors, dentists and mental health.
In addition to housing and health, SiO also offers training services with group lessons, courses, halls and courts. Students can take advantage of discounted personal training rates. The organization also focuses on creating a social environment for students, with food and drink options available in the student environment, as well as nursery arrangements for students with children. SiO is governed by the students themselves, who have a majority in the organisation's top board and thus influence on which services are offered.
