The matter was postponed from February 7 for plea and sentencing agreements, National Prosecuting Authority spokesman Eric Ntabazalila said at the time.
Glenrico Martin, 19, was shot in the back of the head as he entered the Spes Bona Secondary School in Athlone, on the Cape Flats, on May 15, 2013.
Wilston Stoffels, who was 18 at the time of the crime, and Jevon Snyman who was 19, were arrested for his murder.
The two accused remain in police custody. In earlier proceedings, they waived their right to apply for bail.
