The 45-year-old driver was taken into custody until January 4.
He will be sentenced to prison.
Sharon Hands, the headteacher of North Manchester Academy, said: “We are absolutely devastated by this tragedy and our community is deeply saddened.”
“Mia was a friendly, caring, and well-liked member of our school community, who was a role model for others.
“She was selfless, supportive, honest, and thoughtful – those aspects of her personality will remain our strongest memories of her.
“Mia had many friends in school, and they talk about her as being ‘a beautiful soul’ with a contagious laugh and an infectious smile.
“In many ways, Mia represented all that we at Co-op Academy North Manchester hold at our core, and her loss will be felt throughout.
“We are offering all the support we can to Mia’s friends and family and have plans in place to support both pupils and staff at this incredibly sad time.”
