According to the last census, 108,193 Roma citizens live in the Republic of Serbia, and they represent 1.44% of the total population. Because of the frequent migrations and unreported places of residence, it may be considered that this data do not demonstrate the real situation. According to the unofficial data of the Ministry for Human and Minority Rights, it is considered that there are between 400 to 500 thousand Roma citizens in Serbia. Due to a number of economic and social reasons less than 40% of Roma children become part of the overall formal education system. Even though many Non-Governmental Organization （NGO） programs try to include Roma children into educational system, segregation and discrimination are still present. The causes tbr exclusion of the Roma children from the Serbian educational system are numerous： poor economic situation of Roma families, complicated bureaucracy, and low level of competence in language of education, etc.. This paper examines the main reasons for exclusion of the Roma children from the Serbian educational system, and offers some ideas for programs that could change the present situation and help Roma children integrate in educational system and society.展开更多
