The purpose of the study is to examine the ways in which the Children’s rights convention is used to develop early childhood education for children with special needs. We want to examine how preschool teachers and municipalities relate to the Children’s rights convention when decisionmaking concerning children with special needs, and the resources that will be relevant for these children. In order to answer our questions, we conducted interviews with preschool teachers and officials in two municipalities in Sweden. This in order to identify any differences between theory and practice; does this correspond with what is said in the Children’s rights convention, the Education Act, various policy documents that are in and around the preschool or is there a need to develop this work further, so that the guidelines are followed to a greater extent? We have used a qualitative method with phenomenological and phenomenographic basis. We describe the ecological systems theory of child development, individual, and relational perspective, which we use to analyze our collected material. We also shed light on previous research in the Children’s rights convention and children's right to education, the incorporation of the Children’s rights convention, special education and resources, children's perspective and inclusion and exclusion. We have concluded that the need for an education initiative for the Convention should be used to strengthen children's rights, but also the need for a more active work to actualize what is said in the Children’s rights convention.
