A large cement walkway at the school in Vanderbijlpark caved in on Friday, killing three teenagers instantly and leaving more than 20 injured.

A fourth child passed away in hospital on Saturday evening.

Some Grade 12 classes at the school are expected to resume Wednesday. This after the Department of Labour declared some sections of the building safe to use.

Meanwhile, the families of the injured have been posting updates on social media.

It’s understood Grade 9 pupil Shamonè Steynvaart is paralysed from her arms down and Clari Botes, Vanessa Slabbert and Chantelle van den Berg are among those who've had to undergo major surgery.

With broken ribs, pelvic bones and serious back and internal injuries, their road to recovery is likely to be a long one.

Others will have to go back to school soon without the presence of their classmates and friends.

Matrics are returning on Wednesday and the rest of pupils will likely go back to class on Monday.

News24 reported the department's spokesperson, Steve Mabona, announced the funeral arrangements for three of the four pupils on Tuesday morning.

Olckers will be buried on Friday at 15:00 at the Derde Kruis congregation on the corner of Piet Retief Boulevard and Prinsloo Street in Vanderbijlpark.

A memorial service for Currie will be held at the NG south congregation at 1 Schoeman Street at 11:00 on Friday.

Steyn's funeral will be held at the River of Life Church at 22 Elliot Street in Vanderbijlpark on Thursday at 11:00.

Funeral arrangements for Nagel have not yet been announced.
