Education for refugee adolescent girls has faced formidable barriers in transit countries during Covid-19. This thesis is a qualitative case study of the effects of Covid-19 on refugee adolescent girls' education in a transit country (Egypt). The study is based on a conversational interview with Non-Governmental Organization NGO staff in Egypt and a systematic review of NGO reports and field studies of refugee children's education in transit countries to assist the case study with parallel and complementary knowledge from other transit countries. To analyze the interview findings, an Economic Framework for the impact of economic crisis on educational outcomes together with the Sense of Coherence and Waiting concept was used. The case study findings and the literature review summary demonstrated two typologies of vulnerabilities, i.e., general vulnerabilities and specific vulnerabilities. The elements included in the vulnerability category existed before Covid-19; however, Covid-19 caused the intensification of these vulnerability elements, which as a result affected the education of the refugee adolescent girls.
