"Muwanga" and "Nusiriya" schools abides by the Egyptian national curriculum, whereas "Afendiya" follows an American curriculum and teaches lessons in English. These refugee schools face similar problems to public schools in terms of overcrowding. In recent years, "Muwanga" school has seen its student body increase from 400 to 5000 students. Once again, socio-economic conditions prevent many students from entering refugee schools. According to James Natale Finji, a principal of one of the schools, many of his students live in female-headed households, and most of the single mothers work as domestic servants, sometimes in distant cities, or they live in their employers' homes in Cairo. Their daughters sometimes drop out of school to care for their siblings.
