The aim of this essay is to examine how two different schools in Södertälje municipality are working to include and integrate newly arrived high school students in the subject Swedish as a second language. I will do a comparative study in which I study the teachers’ completely opposite way of working to integrate newly arrived school students in the subject Swedish as a second language. I have used a qualitative method where I have conducted interviews. My main theory is Peder Haug's (1998) theory. He uses the concepts of “segregerande integrering” and “inkluderande integrering”. Overall, I would determine that the results of my study suggest that there are many ways that you can work with to achieve integration in school and in the Swedish community. The conclusion of this study is that the newly arrived high school students are integrated in different ways. I have found that the teachers’ in both schools are satisfied with their work and believe that both working methods are aiming at integration. Both schools despite the differences and the similarities in their working methods strive towards the same aim and that is that the newly arrived high school students is going to be integrated in school education and in society.
