School nurses have an important role in helping students to deal with bullying. However, most of the previously undertaken studies do not have nurses as the subjects, considering their experiences around this theme. This study used a qualitative approach through in-depth interviews with 12 school nurses (SNs). The thematic analysis was employed and supported by NVivo 10 software. Five main themes arose from the analysis: (1) understanding about bullying, (2) how they identified bullying, (3) strategies, (4) support at the workplace, and (5) SNs' role. SNs have a reasonable knowledge about this issue and are capable of helping students through dialogue. However, there is a need to be trained and have more time to be able to give proper help to the students, also using other different strategies. SNs must work more actively on this issue with schools and be supported in terms of staff numbers.
