3.5 million children are unschooled.
That 3.5 million figure is according to Unicef. Seventy-five percent of them are girls.
The reasons vary. Violence remains high and widespread. There are too few female teachers, and many families will only let girls be taught by women. For many, going to school means a walk of many miles each day.
In certain parts of the country enjoying relative peace, however, female enrollment seems higher than that of boys.
In central Bamian Province, 58 percent of the 162,000 students are female, according to Ayyub Arvin, the provincial director of education.
