Today the Swedish education system faces major challenges. This research deals with school segregation and the differences in and among Swedish municipalities, more specifically between Kalmar and Karlskrona. There are well-established national goals with the aim to reduce and counteract school segregation, however we tend to find huge differences in the system and performance of schools. All schools have different grounds, conditions and needs and it forces the local government, principals and teachers to act according to factors as resources, priorities, goals and expected behavior within institutions. Deficiencies create the prerequisites for conducting, completing and maintaining the business to the extent that it can be based on the design of the requirements on national level. That brings a great decentralized responsibility and gives room for maneuver and freedom of action for street-level bureaucrats, that may not maintain national standards. The purpose of this research is to analyse how enforcement of national goals in each municipality, at local schools,  that either are segregated or may become and then compare them to see the difference. In conclusion the analysis show that national goals are used as guidelines in municipalities, but all municipalities establish their own goals according to the conditions and needs of the school. The difference that exist between schools depends on local circumstances.
