Although Sudanese children were granted the right to free primary education in 2000, the cumbersome entry process for Sudanese children hinders access to public schools. The Egyptian Ministry of Education requires that Sudanese provide documentation from previous schools, a birth certificate and residency permit or "iqama". Residency permits are often too expensive for Sudanese families, and having spent their lives as IDPs in Sudan, many children do not have the necessary documentation. For those children who are able to attend public primary schools, some are subject to bullying and harassment because of skin colour.
