For the past decade, Sweden has been reinforced as a multicultural society, and immigrant integration policy has been a hotly debated topic. During the election campaigns in 2022, preschool was an important political issue, the government arguing that early interventions can be the key to the successful integration of immigrants. Subsequent amendments to the Education Act, which entered into force on 1 July 2023, require all municipalities to actively promote increased participation in preschool by means of different methods. The municipalities must provide information to parents and legal guardians and offer preschool enrollment to children who need learning Swedish, without the parents or legal guardians applying for it. The outreach activities are aimed at children who are not currently enrolled in preschool but who are entitled to be. The purpose of the present thesis is to investigate the experiences among preschool staff of the requirement to take active measures to offer preschool enrollment to the children of foreign-born parents. Through a qualitative approach with semi-structured interviews and a street level bureaucrats theoretical perspective, the study has focused on two municipalities which have charged preschool staff with the aforementioned task. With the analytical terms street level bureaucrats and discretion, it has been possible to investigate how the policy is implemented and how the preschool staff feels about being a fellow human being as well as an agent for a government authority. The results of the study indicate a consensus among preschool staff that they understand the purpose of, and need for, active measures, and their good intentions and ambitions are visible, despite being insufficiently prepared for the task by their employers.
