In order for special educators and specialist teachers to be able to support multilingual students, a mapping system is needed in the student’s mother tongue. It’s needed because special educators and specialist teachers should, in the best possible way, be able to assess and offer the support that a multilingual student need. The purpose of the study is to analyze in detail how special educators and specialist teachers work to support multilingual students who have dyslexia. The study has the socio-cultural perspective as a theoretical starting point and the reason for that is that the socio-cultural perspective focuses on learning and the learning of individuals in social contexts. The scientific approach that becomes current and applied in the study is qualitative research method and the applicable method is semi- structured qualitative interview, where four special educators and two specialist teachers are interviewed regarding their work to support multilingual students with dyslexia. The result of the study is that screening tests can determine if a student has dyslexia and therefore assess the support that is required. If a student has dyslexia in Swedish, the student will also have it in their mother tongue. Since the tests are performed in Swedish, in order to be able to process dyslexia in the best possible way, you have to map the difficulty in both the students mother tongue and Swedish.
