Until 1929, when her parents divorced, Kerkhoven went to a private school in the Dutch East Indies. Then, Kerkhoven went to primary and secondary school in
The Hague, the Netherlands, but did final exams in the East Indies again. In the following period, Kerkhoven studied medicine at the Medische Hogeschool (medical University) in
Batavia. Here she needed to perform vivisection which, as a strict vegetarian and animal lover, she didn't want to. Therefore, in 1938, she went to the
University of Groningen, one of the few Universities that didn't have an obligation to perform
vivisection during medicine study. She lived with the Hendriks family, which she later joined in the World War II-resistance. A month after starting her degree of studies, Kerkhoven started publishing in student paper Der Clercke Cronike. She wrote pieces stating her
pacifism and about the German occupation in WWII, which were sometimes misunderstood and heavily discussed. Kerkhoven said the Jewish persecution was a result of mass insanity. Her last article for the Cronike ended: "whoever can risk their life for military defense, can also risk it for pacifist defense." At the time of her study, Kerkhoven was also part of Dye Line Trekkers, a drawing society affiliated with
student society Magna Pete. This society was led by Groningen painter
Johan Dijkstra, one of the founders of the Groningen art circle
De Ploeg. Here, Kerkhoven stood as a model for various paintings. ==During World War II==
