The COVID-19 pandemic has had a vast influence on Swedish society. Related recommendations and political decisions have greatly affected schools. This study aimed to describe school nurses' experience working in Sweden during the pandemic in 2020. The study used a qualitative method with an inductive approach. Interviews with 17 school nurses in five focus groups and one individual interview were conducted. Qualitative content analysis was used. The impact of the pandemic on school nurses can be described through three categories: "Changes in working methods in relation to the students/guardians", "Impact on cooperation with school staff", and "The school nurse's prerequisites for major changes." Overall, school nurses experienced a transition to a digital way of working. Policies and decisions on global and local levels affected the work situations of school nurses as well as the school nurses' social, cultural, and professional experience. The highest priority for school nurses is students, and school nurses adapted their working methods to give support to students during the changing circumstances. School nurses are both pragmatic and highly creative. Cooperation with other school professions is critical, as is support and guidance during crisis situations.
