In the late 18th century and early 19th century private schools for girls were established in Finland, among the more known being those of Christina Krook, Anna Salmberg and Sara Wacklin. These schools were criticized for its shallow education of accomplishments, which resulted in the decision that girls should be included in the school reform of 1843, and the following year, two Swedish-language state schools for girls was founded in Turku and Helsinki, Svenska fruntimmersskolan i Abo and Svenska fruntimmersskolan i Helsingfors. This led to the establishment of a net of girl schools of a similar kind in Finland. At first the schools were reserved for girls from upper-class families.  At this time it was not possible for the girls to pass the baccalaureate and move on to university studies. In 1865 a grammar school made it clear that only girls whose upbringing and manners were impeccable and whose company can't be considered detrimental to others, and who were from "respectable" families could be in the school.  After the first woman in Finland, Maria Tschetschulin, was accepted as a university student by dispensation in 1870, advanced classes and colleges classes were included in many girl schools to prepare students for university (by means of dispensation), and in 1872, the demand that all students must be members of the Swedish language upper classes was dropped. Women were given the right to teach in grammar schools for girls in 1882.  When the dispensation for female university students was dropped and women were accepted at the same terms as men in 1915, girls and boys started to receive the same education in the school system, and the girl schools in Finland started to be changed to same sex education, a development which was completed in the 1970s.
