After the war, the Evangelical Youth Association got an idea to establish an evangelical school and during a meeting in December 1946 they formed a supporters' association for the school. Despite some setbacks, the school could begin operations in June 1947. Because there were a shortages of everything after the war, the donation of apples just before the initiation, in November 1947, were very suitable. Mistress Greta Selenius and needlework teacher Helen Lindqvist made ovenapples with custard, which was perceived as a real feast at the initiation.
A tradition which has followed since the start are the popular “Student association”-days when former and current students meet and socialize in a Christian spirit on a weekend once a year. This gives an insight into how important the school has been for many of it´s students when they return every year to the “Student association”-days.
The Evangelical Youth Association worked hard to collect donations from the beginning of the school´s activities, so that they could award scholarships to poor students who might not have had the opportunity to study without this gift. This custom still continues, the school has annually various scholars from the Baltic countries, Estonia and Latvia, as well as from their own country. New since the school year 2005-2006 are also two scholarships for students from Finland that the “Friends of the school” have donated.
The school's study range has varied over the years, but the christian perspective have always been the foundation. In the 1970s there was a structural change in the folk highschools, when the general school range no longer interested students. The school then founded specific programmes, some of which include a “Developing country”-course and “Developing country”-program, later Social science-juridical-, Mission and Culture-, Film and video-, Journalistic-, Baltic culture-, and Study and Weaving program. A new program was also the Performance art program.
Also the trip to Ostrobothnia each spring has a long history behind it. At first it was only the principal who traveled to meet with the school friends who live in Ostrobothnia, but already for a long time, the school's students had gone too, and together they participated in religious services and gatherings.
The school's students have often been responsible for various program activities such as singing and theater. Students have also been acquainted with the local sights. Similarly, the trip to the Baltics became a tradition. That will ensure the school's students with the principal and various teachers at the various Baltic countries to study each country's history and culture. The school's film line also makes a film about the journey as a student work each year.
Given that the school turned 70 in 2017, it is a vital and lifestrong school, where a cozy mood and concern for others is strong. Many of the students have returned to work as teachers and so have many of those who worked at the school returned.

The Guesthouse started its activities in the B-side building to support school activities and expanded in conjunction with the finishing of the new A-side building in 1990. The new building functioned primarily as a boarding school for students during term time. The construction works on the A-side started in 1989. The building was completed in July 1990 when then defense minister and Member of Parliament Elisabeth Rehn opened it. The house consists of 12 rooms, with shower and toilet in each room, and two lounges with fireplaces, TVs and fully equipped kitchenettes.
