This school boasts a top place in Gauteng education, but it isn't an achievement to be proud of - last year, a staggering 71 of its pupils were pregnant.
And the pregnant pupils at Altmont Technical School in Soweto are only a fraction of the 2 336 Gauteng schoolgirls who became pregnant last year - a figure that is double that recorded in 2005.
But, while the Gauteng education department on Sunday admitted that the pupil pregnancy figures were "shocking", it insisted that "(the pregnancies) are not our problem".
In a move that has been criticised by child rights and media freedom experts, the department has also threatened to take action against Democratic Alliance Gauteng MPL Jack Bloom, who released the statistics to the media.
Gauteng education MEC Angie Motshekga last week provided a written response to Bloom's questions about the number of pregnant schoolgirls in the province.
Bloom then relayed Motshekga's response to the media, highlighting the fact that the Gauteng pregnancy statistics had grown "alarmingly" from 2004/2005 - when there were respectively 1 373 and 1 169 schoolgirls reported as pregnant.
He also reported that, according to Motshekga, 61 pupils had fallen pregnant at Raphela Secondary School in Orange Farm, 45 at TM Letlhake Secondary School in Westonaria and 23 at the Bhukulani School in Zondi, Soweto.
This, Bloom said, showed that "we need a drastic rethink of our failed sex education at schools" and indicated that he would call for a debate in the Gauteng Legislature on "what we can do to prevent teenage pregnancies and the risky sexual behaviour that spreads the HIV/Aids epidemic".
Bloom's media release unleashed a political firestorm, with Motshekga's spokesperson, Panyaza Lesufi, slamming Bloom for using his power to ask questions in the legislature "under false pretences" and for "political point-scoring".
"The questions that Bloom asked were meant for legislature purposes only... They were not intended to be released to the public," he told The Star, adding Bloom was "barking up the wrong tree".
"The issue of children and teenagers falling pregnant is a social issue... It is not our problem and now we are being accused as if we were directly responsible for impregnating these learners.
"Can we really be crucified for keeping records about a social problem and then providing this information (to a political party)?" he asked, decrying what he described as the DA's "sad" misuse of the pregnancy statistics.
Lesufi said his department would consider "not providing the DA with the information they require in the form that they want" next time the party asked questions in the legislature.
Asked for comment, Bloom, who is the DA spokesperson on health in Gauteng, said: "His (Lesufi's) tirade was totally uncalled for."
And it seems Bloom has the backing of Gauteng Legislature Speaker Richard Mdakane, who on Sunday told The Star Bloom had done nothing wrong in reporting Motshekga's answer to the media. He stressed that departments were not allowed to withhold information when it was requested from them in the legislature.
"The answers are public documents and they can and may be used against departments by their political opponents... That is the nature of politics," he said.
Childline head Joan van Niekerk on Sunday expressed dismay at Lesufi's slating of Bloom.
"For me it's not about apportioning blame or saying that a specific government department is responsible for what clearly is a major problem... It's about knowing the real extent of that problem so that we can all deal with it properly," she said.
"We need to be thinking, together - about how we educate our children about sex and how, if a child does become pregnant, we help her and the child that she is carrying."
Pointing to loveLife research which revealed that about 80 percent of young adults claimed their first sexual experience was not consensual, Van Niekerk said the education department's apparent attempts to censor Bloom could prevent the issue of sexual coercion and rape of children from being properly exposed.
Media Institute of South Africa head Raymond Louw said the education department's attitude reflected a growing and disturbing trend of information suppression "of any information construed as embarrassing" by government officials.
Meanwhile, the Gauteng education and health departments insist they are doing everything they can to address the evidently rampant practice of unprotected sex in many schools.
Health spokesperson Bhungani Mzolo stressed that birth control was easy for young people to access, with the department creating youth-friendly clinics where youngsters could discuss contraception freely.
He added that the department's research had revealed that the problem of teenage pregnancy was concentrated in informal settlements.
"In some instances, poverty is so rife that some girls will fall pregnant in order to get the child-support grant for survival, while others are from child-headed families and will do anything to put food on the table," Mzolo said.
Research conducted at 120 KwaZulu-Natal schools since 2004 found that the age at which most schoolgirls fell pregnant was 16, but noted pregnancies in girls as young as 11.
Statistics showed that 887 schoolgirls had fallen pregnant in KwaZulu-Natal last year.
