Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
Gauteng education MEC Angie Motshekga has urged principals and teachers to improve the province's low pass rate.
Motshekga made the call at a regional education summit held at the Soweto College of Education in Pimville at the weekend.
She also named the schools that were performing poorly.
Some of the schools named were Mncube, Lobone, Ibhongo and Senaoane secondary schools; Nghunghunyani and Fontanus comprehensive schools.
Motshekga said the schools had all achieved a pass rate below 60percent last year.
"Statistics show that for the last three years these schools have not been doing the business of a school," she said.
She also said teachers had to get rid of the thinking that because their schools were located in poor areas, they were justified in performing poorly.
Motshekga said Soweto was once one of the best performing locations and had produced great leaders.
"The best African mathematician, Professor Thamsanqa Kambule, came from and taught in the area for a long time, producing good results and the most disciplined group of learners," she said.
She said scholars such as Lekgau Mathabathe, Gabriel Madida, Mrs Ngidi, FK Matseke, Phillip Mehlape and HH Dhlamlenze never produced poor results, even during difficult times.
She also said the economic success or failure of the country was entirely in the hands of principals and teachers.
"How can you expect to give birth to other professionals when you are unable to reach a mere 60percent in your matric results?
"If this situation continues unabated, the future of this country, province and, most importantly, of these learners is not guaranteed at all, and yet that guarantee is in the hands of teachers and education managers," said Motshekga.
