The Juvenile Justice Board has charged the boy with rape, murder and other crimes, including kidnapping. It set 6 March as the start of the trial.
If convicted, he faces a maximum of three years in a reform facility.
Five other suspects have gone on trial at a specially convened fast-track court and face the death penalty.

The brutal assault shocked India and raised a debate over the treatment of women in the country.
The victim, a physiotherapy student who cannot be named in India for legal reasons, and a male friend were attacked on a bus on 16 December.
Police said the assailants beat both of them, and then raped the woman. She suffered massive internal injuries and died nearly two weeks later.
