The aim of the study has been to investigate school counselors' preventive work against bullying in school and what opportunities and obstacles are found in their work. The study is based on seven qualitative interviews where the interviewees have varying backgrounds and experiences surrounding school counselor work. A constant throughout the study is that the school counselor is in a multiprofessional operation and is usually the only profession based in a psychosocial perspective. The school counselor’s tasks are characterized primarily by an overall responsibility for students’ wellbeing, as well as working to prevent bullying. As bullying can result in students performing worse as well as a risk for developing an antisocial behavior, the school counselor’s important preventive work follows. The preventive measures can be seen on a school, class and individual level, which creates a holistic perspective. Factors such as time and resources prevent the school counselor from practicing their knowledge in school, as well as limit their collaboration with other professions. Along this reasoning follows the interviewees’ similar opinions that the principal has a noticeable influence on counseling work and can increase or limit their ability to practice their knowledge. With the help of our theoretical templates we have a better understanding of our analysis, which has helped us understand the school counselor’s role in a multiprofessional operation.
