School is compulsory for all children aged between 6 and 16 in Sweden. It is a second home for all children. School segregation is essentially a question of importance in today's society. School segregation shows that the crucial factors leading to school being divided is due to factors such as family background (ethnicity) and socio-economic situation. Therefore, it contradicts the social cohesion and quality that schools strive for. Thus, possibly resulting in schools not maintaining an equally consistent quality because in some school’s children perform better than others. Hence, in the teaching profession, we believe that the school's social cohesion and working methods have very important functions for creating quality in the presentation of the right knowledge and good community. Consequently, this is the reason why we chose to investigate further what research says about school segregation. School segregation is a relevant societal topic to raise in the teaching profession. In order to be able to counteract and know the conditions of the schools, one must have sufficient underlying knowledge about what it is that affects the school's quality. Thus, in this study we want to furthermore explain what school segregation research reports in Sweden. This research overview has managed to collect from search engines like Swepub, Libris and governmental websites as IFAU and Skolverket ten scientific reports on school segregation that have later been discussed further, and a conclusion has been drawn on the project work. The conclusion that we can draw from this research overview work is that there is a rich amount of information sources about school segregation which one can take part in. They are very similar in the form of the presentation about the causes of school segregation, as well as consequences that a larger project work can be very useful from.
