School segregation of Roma has become one of the most studied disciplines in the field of education in the last 20 years. Even though research mentions its persistence, no studies have shown how it persists, this study aims to fill this gap in the specialized literature. Based on the analysis of several reports, this qualitative study aims to show how the school segregation of Roma in Romania survives in the mainstream education system. Despite the fact that in 2004 the state recognized the seriousness of the problem and introduced Ordinance 1540/2007 prohibiting all forms of school segregation, many public-school units in Romania continue to practice this form of discrimination against Roma children. School segregation is a persistent problem in Romania, and studies show that between 1998 and 2016, the proportion of segregated schools increased significantly, becoming a barrier in the Roma integration process. The recommendations of the study on solutions against the school segregation of Roma children aim to involve Roma civil society in the process of monitoring segregated schools, enrolling Roma children from residentially segregated communities in mixed schools and informing parents about the consequences of segregation on Roma children.
