Clare Woodcock, a spokeswoman for the university, confirmed on Tuesday that Ms. Yousafzai has enrolled at Oxford but said the school would make no further comment. Ms. Yousafzai had said in August that she would study philosophy, politics and economics.

At a young age, Ms. Yousafzai became a high-profile advocate for the education of girls. She appeared alongside her father, Ziauddin Yousafzai, the owner of a girls’ school, in a 2009 New York Times documentary about the Taliban edict that forbade girls from attending classes.

Using a pen name, she wrote blog posts for the BBC about life in the Swat Valley, an area of Pakistan that was largely controlled at the time by the Taliban. In 2011, she was awarded Pakistan’s first National Youth Peace Prize. It has since been renamed the National Malala Peace Prize.

But her efforts to bring change to the Swat Valley also made Ms. Yousafzai a target. On Oct. 9, 2012, when she was 15, a Taliban gunman boarded her school bus, asked for her by name and shot her in the head and neck.
