Refugees who come through immigration have many problems. The most important of these is the problem of communication, namely language. Knowing the language of the country they migrated to means to find a job for refugees, to continue their education and to continue their lives in a more orderly manner. In recent years our country to adapt to the life of the remaining Syrians forced to migrate to Turkey many studies are conducted. Providing educational opportunities for Syrian children at the age of compulsory education and opening Turkish courses for those who want to learn Turkish from all ages are some of these activities. Our study, which we conducted to measure and evaluate the Turkish expressive language skills of Syrian children in Izmir, includes 14 Syrian children at the 8th grade who are studying in official secondary schools affiliated to the Ministry of National Education in Buca district. The study was carried out with the in-depth interview method, which is a qualitative method, and the speeches obtained were analyzed linguistically according to the error analysis approach. Phonological, morphological, semantic and syntactic mistakes made by the participants during the speech were identified and interpreted. Accordingly, the most common mistakes with 76, 78% are phonetic errors. It was followed by morphological errors with 17,36%, syntactic errors with 4, 03% and semantic errors with 1, 81%. With this study, it is aimed to fill an important gap in terms of evaluating the Turkish speaking skills of Syrian refugee children with the error analysis approach and to shed light on the teaching processes of Turkish teachers.
