He is being charged with attempted murder, but the 28-year-old man's defence lawyer wants the charge reduced to assault.
Swedish Radio reports that the man believed he had killed the girl and fled to Spain after the February attack.
In court on Tuesday, a recording of the initial police interview with the victim was shown. Speaking from her hospital bed, the girl recounts how she was on her way home from school when she noticed someone was following her.
She was pushed to the ground and shortly afterwards realised she had a knife sticking out of her throat. She was transported to hospital with the weapon still in place.
"She still has pain in her back, one hand and in her foot," says the girl's lawyer, Camilla Wester.
"Psychologically, she suffers from anxiety, because she is of course undergoing a crisis," Wester adds. "But she is receiving help."
Swedish Radio reports that her suspected attacker showed no signs of emotions in court.
