For most teenage girls in Afghanistan, it’s been a year since they set foot in a classroom. With no sign the ruling Taliban will allow them back to school, some are trying to find ways to keep education from stalling for a generation of young women.

At a house in Kabul, dozens gathered on a recent day for classes in an informal school set up by Sodaba Nazhand. She and her sister teach English, science, and math to girls who should be in secondary school.

“When the Taliban wanted to take away the rights of education and the rights of work from women, I wanted to stand against their decision by teaching these girls,” Ms. Nazhand told The Associated Press.

Hers is one of a number of underground schools in operation since the Taliban took over the country a year ago and banned girls from continuing their education past the sixth grade. While the Taliban have permitted women to continue attending universities, this exception will become irrelevant when there are no more girls graduating from high schools.
