Preschool teachers in Sweden are bound by the mandatory reporting process which is found in Socialtjänstlagen. This means that if they are worried that a child is being harmed, they must report this to the social services. The aim of this qualitative study is to investigate how the mandatory reporting process is applied at preschools. To investigate this, the participants gradually took part in a fictive case where they got to decide at what stage in the case they would file a report. After completing the case, the participants got to participate in a detached interview. The interview was mainly based on the routines to file a report and what the participant considered to be the hardest part with the mandatory reporting process. The main finding in this study is that there is no relation between age and experience when it comes to previous reports although the number of reports varied among the participants. The results also showed that age and experience played no part in the decision making regarding filing a report. A majority of the 5 participants chose to report after reading the second page of the case while the remaining two chose to report after reading the third page of the case. The common view concerning neglect among the participants is that it is easier to identify signs of physical neglect than psychological neglect.
