The mathematics classroom at Sizwe Secondary School in Soweto was designed for 35 learners. On a Tuesday morning in late April, 73 of them sat shoulder to shoulder, their desks arranged in rows so tight that the teacher cannot walk between them. To reach a student in the back, she must ask three others to stand and press themselves against the wall.
The chalkboard is a distant smudge for those behind the tenth row. The air is thick with the heat of too many bodies and not enough windows. The only fan, mounted high on a wall, stirs nothing but dust.
“I have 73 children in a room meant for half that number,” said Mrs. Nomsa Dlamini, a 28-year veteran of Gauteng’s public school system, her voice hoarse from speaking over the constant murmur. “I cannot give them individual attention. I cannot hear their questions. I cannot even remember all their names. How am I supposed to teach?”
She is not alone. Across Gauteng—South Africa’s smallest but most populous province—public schools are buckling under the weight of an enrollment crisis that has been decades in the making. In some township and inner-city classrooms, the pupil-to-teacher ratio has hit an astonishing 70 to 1. In a few extreme cases, educators report numbers as high as 85 to 1.
The result, according to teachers, parents, and education experts, is a system in which learning has become almost impossible—and the promised dream of quality education for all is dying in the overcrowded dust.
The Numbers That Should Shock the Nation
The Department of Basic Education’s own norms and standards specify a maximum pupil-to-teacher ratio of 35 to 1 for secondary schools and 40 to 1 for primary schools. But in Gauteng’s townships—places like Soweto, Tembisa, Alexandra, and Diepkloof—those numbers have become a cruel joke.
A survey conducted by the Gauteng branch of the South African Democratic Teachers’ Union (SADTU) last month found that:
- 62% of township schools reported at least one classroom with more than 50 pupils.
- 28% reported classrooms exceeding 60 pupils.
- 11% reported classrooms of 70 or more.
In inner-city Johannesburg, the situation is even more acute. Former “model C” schools, once the preserve of white suburbs, are now bursting at the seams as middle-class families flee crumbling facilities and desperate parents seek any space for their children.
“I applied to seven schools before I found a place for my son,” said Thandi Mkhize, a mother of two who lives in a high-rise flat in Hillbrow. “The seventh school took him because they had no choice. His classroom has 68 children. He brings home worksheets that are never marked. He says the teacher just writes on the board and they copy. He is in Grade 5. He cannot read.”
The consequences are not abstract. International assessments, including the Progress in International Reading Literacy Study (PIRLS), have consistently shown that South African learners lag far behind their peers in other middle-income countries. Overcrowding is a major driver of that failure.
“In a class of 70, differentiation is impossible,” said Professor Mary Metcalfe, a former Gauteng MEC for Education and now an education analyst at the University of the Witwatersrand. “A teacher cannot identify the struggling learner in the back row. Cannot extend the gifted learner in the front. Cannot manage behavior effectively. Cannot assess meaningfully. The curriculum becomes a delivery mechanism for the few at the top, and the rest are left behind. That is not education. That is warehousing.”
The Daily Reality: A Teacher’s Lament
To understand the crisis, one must spend a day in the shoes of a teacher like Mrs. Dlamini. Her alarm rings at 4:30 AM. She is at school by 6:30, an hour before the first bell, to prepare lessons and mark the few assignments she has managed to collect.
By 7:30, the first students begin to arrive. By 8:00, her classroom is full. By 8:15, it is overflowing.
“The latecomers stand at the back. There are no chairs. Some bring their own plastic stools. Some just stand for the full hour. How can a child learn while standing?”
She describes a typical lesson: a 45-minute period in which she must deliver content, check for understanding, and manage behavior—all while barely able to move.
“I write on the board. Those in the front can see. Those in the back cannot. So I read aloud what I write. But when I read aloud, the noise in the room rises because the children in the back start talking—they cannot see or hear anyway, so why pay attention? I stop reading to ask for quiet. That takes two minutes. I resume reading. The noise rises again. By the end of the period, I have covered half of what I planned. The children have learned a quarter of that. And I am exhausted.”
Her afternoons are spent in department meetings, parent calls, and administrative paperwork—none of which is reduced by overcrowding. She leaves school at 4:30 PM, carries marking home in a bag that weighs 15 kilograms, and works until 10:00 PM.
“I love teaching,” she said, her voice breaking. “I chose this profession. But I am not teaching anymore. I am crowd control. And my students are the victims.”
The Infrastructure Gap: Not Enough Schools, Not Enough Rooms
Behind the human crisis lies a simple, brutal arithmetic: Gauteng is growing faster than it can build.
The province receives an estimated 150,000 new migrants each year—people moving from other provinces and across South Africa’s borders in search of jobs, opportunity, and better services. A significant proportion are families with school-aged children.
Yet the rate of school construction has not kept pace. According to the Gauteng Department of Education, the province needs at least 30 new schools every year just to maintain current overcrowding levels. In reality, it builds between 5 and 10.
“My child is on a waiting list. There are 400 names on the list. She has been there for two years,” said Bongani Ndlovu, a father of three who lives in Diepsloot, a densely populated informal settlement north of Johannesburg. “The school is 5 kilometers away. She walks. She is 9 years old. She walks alone because I am at work. I am terrified every day. But what can I do? There is no other school.”
Even where schools exist, their physical infrastructure is often inadequate. Many schools in townships and inner-city areas were built in the 1970s and 1980s for smaller populations. Adding prefabricated classrooms—so-called “mobile” units—has provided some relief, but those structures are often cramped, poorly ventilated, and prone to leaking in summer rains.
“The mobile classrooms were meant to be temporary,” said a school principal in Tembisa, who asked not to be named. “Some of ours have been here for 15 years. They are falling apart. But we have no choice. The main building cannot fit the children. So we use the mobiles. And we pray the roof does not fall.”
The Policy Failures: A Perfect Storm
The overcrowding crisis is not an accident. It is the predictable result of years of policy failures, budget shortfalls, and political negligence, according to critics.
The Gauteng Department of Education’s budget has been squeezed for several consecutive years. While the provincial government has prioritized education—it remains the largest line item—the percentage increase has not kept pace with inflation or enrollment growth.
“We are trying to do more with less,” said a senior official at the department, speaking on condition of anonymity. “The national government allocates funding based on outdated formulas. The province tops it up as best we can. But the demand is simply overwhelming. We are building as fast as we can. But building a school takes three years from planning to opening. The population grows faster.”
The official also pointed to a contentious policy: the “no-fee school” designation, which has made Gauteng’s public schools free for most families. While the policy has increased access—a noble goal—it has also eliminated the market-based pressure that might otherwise distribute students more evenly.
“Parents will always choose the school they perceive as best,” said Professor Metcalfe. “In a system with no fees, the only barrier is proximity. So everyone flocks to the schools with the best reputation, overcrowding them, while other schools sit half-empty. That is not efficient. And it is not fair.”
The Human Cost: Mental Health, Dropouts, and Lost Potential
The consequences of overcrowding extend far beyond test scores. Teachers and counselors report rising rates of anxiety, depression, and behavioral problems among students in overcrowded classrooms.
“Children need to feel seen to feel safe,” said Thabo Mokoena, a school psychologist who works across three Soweto schools. “When a child is one of 70 in a room, they are not seen. They become invisible. Invisibility leads to disengagement. Disengagement leads to acting out. Acting out leads to punishment. Punishment leads to dropout. That is the pipeline.”
Dropout rates in Gauteng have been creeping upward, particularly among boys in Grade 10 and 11. While no single factor explains the trend, overcrowding is a significant contributor.
“Why stay in school if the teacher does not know your name?” said Sipho Zungu, 17, who dropped out of a Tembisa high school last year. “I was in the back row. I never got called on. I never got help. I was just a body in a chair. So I left. Now I wash cars. I make R200 a day. It’s not much. But it’s better than sitting in a room where no one cares if I learn.”
His story is repeated thousands of times across the province. Each dropout represents not just a personal tragedy but a long-term economic drain—a young person who will struggle to find formal employment, will likely earn less over their lifetime, and is more vulnerable to crime, substance abuse, and social instability.
The Teachers’ Exodus: A Profession in Crisis
Overcrowding is also driving teachers away from the profession, exacerbating the very shortage that fuels the crisis.
A recent survey by the Gauteng Department of Education found that 40% of teachers in township schools are considering leaving the profession within the next two years. The top reason cited? Overcrowding.
“I cry in my car almost every day after school,” said a young teacher in Alexandra who asked to be identified only as Miss K. “I wanted to change lives. Instead, I am drowning. I cannot help these children. I am not helping them. I am just surviving. And I don’t know how much longer I can do this.”
Miss K, 26, is in her fourth year of teaching. She started with 40 learners in her classroom. She now has 68. Her salary has not increased significantly. Her workload has doubled. She has started seeing a therapist.
“I love my students,” she said, wiping tears. “They deserve better. But I also deserve to be okay. And I am not okay.”
The Political Response: Promises and Pilots
The Gauteng Department of Education has not been silent on the crisis. MEC for Education Matome Chiloane has acknowledged the severity of the problem in multiple media appearances and legislative briefings.
“We are dealing with a perfect storm of migration, population growth, and infrastructure backlogs,” Chiloane told the Gauteng Legislature last month. “We are not making excuses. We are stating facts. And we are acting.”
The department has launched several initiatives, including:
- The “School of Specialisation” model: Converting some underperforming schools into focused academies (maths and science, arts, commerce) to attract students away from overcrowded generalist schools.
- Double-shift schooling: In some inner-city schools, two separate cohorts of students use the same classrooms—one from 7 AM to 1 PM, another from 12 PM to 6 PM. While controversial, the approach has increased capacity without new buildings.
- Public-private partnerships: The department has invited private companies and foundations to fund the construction of new classrooms, with mixed results.
- Mobile school units: A fleet of prefabricated classrooms on trucks that can be deployed to areas of acute need within weeks.
Critics argue these measures are Band-Aids on a hemorrhage.
“Double-shift schooling means shorter learning days. Mobile units are cramped and poorly equipped. Specialisation schools help at the margins but do nothing for the average learner,” said Nkosana Mncube, a researcher at the Centre for Education Rights and Transformation at the University of Johannesburg. “What we need is a massive, sustained, multi-year infrastructure build. What we are getting is pilot projects and press releases.”
The Parents’ Revolt: Anger and Action
Frustrated parents are beginning to organize. In several communities, parent associations have filed formal complaints with the Public Protector and the South African Human Rights Commission, arguing that overcrowding violates children’s constitutional right to basic education.
“Section 29 of the Constitution says everyone has the right to a basic education, including adult basic education, and to further education, which the state, through reasonable measures, must make progressively available and accessible,” said attorney Puseletso Mofokeng, who is representing a group of parents from Tembisa. “Seventy children in a classroom is not a reasonable measure. It is a violation.”
A class-action lawsuit is currently being explored, though no papers have yet been filed. The legal threshold for proving a violation of the right to education is high, and courts have historically been reluctant to intervene in resource allocation decisions.
But parents say they have no other recourse.
“We have written letters. We have marched. We have met with officials. Nothing changes,” said Nokuthula Dlamini, chairperson of the Alexandra Parent Forum. “So now we go to court. We do not want to sue the government. We want the government to do its job. But if they will not listen, we will make them listen.”
The Way Forward: What Would It Take?
Solving Gauteng’s overcrowding crisis will require political will, financial investment, and a willingness to challenge entrenched interests. Education economists estimate that bringing all Gauteng classrooms down to a ratio of 35 to 1 would require:
- Construction of 120 new schools over five years (24 per year, up from the current average of 5–10).
- Hiring of 8,000 new teachers (to reduce workload on existing staff).
- Annual budget increase of R4.5 billion for infrastructure and personnel.
In a province facing competing demands for healthcare, housing, and social services—and a national fiscus under pressure—those numbers are daunting.
“It’s not impossible,” said Professor Metcalfe. “It’s a question of prioritization. If the government decided that fixing education was its single most important task, the money could be found. But it requires saying no to other things. That is the hard part of politics.”
Epilogue: A Single Classroom, A Million Hopes
As the final bell rings at Sizwe Secondary School, Mrs. Dlamini watches her 73 students shuffle out of the classroom. They leave behind a sea of crumpled papers, a broken desk, and a silence that feels almost sacred after seven hours of noise.
She picks up a broom and begins to sweep. Tomorrow, the room will fill again. The back row students will stand again. The lesson will be interrupted again. The cycle will continue.
But in her pocket is a note that a student slipped to her during the lunch break. It is written on a torn piece of notebook paper, in pencil, the handwriting shaky.
“Miss D, I know you have many children. But I want you to know you are the only one who sees me. Thank you for not giving up. I will make you proud.”
Mrs. Dlamini folds the note carefully and places it in her wallet, next to a photograph of her own grandchildren.
“One child,” she whispers. “If I can reach one child in that room, it is worth it. One child.”
She locks the classroom door. Outside, the sun is setting over Soweto, casting long shadows across the empty playground. And somewhere in the distance, another school bell rings—another classroom filling with 70 souls, one teacher, and the impossible weight of a nation’s hopes.
