The purpose of this thesis is to analyze which factors that enables the implementation of UN’s Convention on the Rights of the Child to differ in different places in Sweden. The aim of this study is achieved by analyzing two study objects that both have been implementing the Convention on the Rights of the Child with the help of the implementation theory. The study objects that are analyzed in this case are the municipality of Kalmar and municipality of Örebro. This study uses a deductive- and to some extent also an abductive research method and analyzes the results of the study with the help of implementation analysis. Using the theory of implementation, the author makes assumptions related to the study's empirical study. In order to later serve as explanations for why the implementation has differences in different municipalities around Sweden. The result of this study is based on the municipalities own strategy plans for implementing the Convention on the Rights of the Child, together with the Swedish law about UN’s Convention on the Rights of the Child. The result of this thesis shows that the new legislation requires a joint power collection among all decision-makers. This means that municipalities must actively work to implement the legislation in their operations. The result of this study also shows that there are differences between how the investigated municipalities implemented law about UN’s Convention on the Rights of the Child in their operations. This thesis shows that what separates the study objects in this case it is whether or not there is a political council decision, to which the knowledge-enhancing efforts are directed, number of employees who will work with the Convention on Rights of the child and the intensity of the work with follow-up and evaluation work. In this case, the differences in the implementation can be explained by, among other things, unclear and difficult legislation, a lack of state financial and material instruments, that the implementation has taken place in several stages and a lack of understanding of the policy to implemented. The study highlights that the deciding factor for differences in the implementation of UN’s Convention on the Rights of the Child has to do with the unclear and incomprehensible legislation.
