Complete Guide to Schools in Cosmo City 2026 — Primary, High Schools and Pre-Schools
Choosing the right school is one of the most important decisions a Cosmo City family makes. Whether you are enrolling a Grade 1 learner for the first time, relocating to the area, or exploring alternatives for a child already in school, this guide covers every public school in Cosmo City — from early childhood development centres to high schools — along with what parents need to know about the admission process, school fees, and the realities facing local schools right now.
Every School in Cosmo City at a Glance
Cosmo City has a well-developed schooling infrastructure for a suburban area of its size. The suburb is served by a mix of public primary schools, one of the largest public high schools in the northern suburbs, and a growing number of registered ECD (Early Childhood Development) and pre-school facilities.
Most public schools in Cosmo City fall under the Gauteng Department of Education’s (GDE) Region D, which administers schools across the northern corridor of Johannesburg including Randburg, Cosmo City, Bloubosrand, Roodepoort, and surroundings.
Primary Schools in Cosmo City

Cosmo City Junior Primary School
This school has received significant media attention recently due to severe overcrowding. In 2025, the school was reported to have 92 Grade 1 learners sharing a single classroom — a situation that reflects the pressure that population growth has placed on Cosmo City’s educational infrastructure.
The school continues to operate and serve the community, and the overcrowding situation has been raised with the GDE. Parents considering this school for Grade R or Grade 1 placement should contact the school directly to understand current class sizes and whether the situation has been addressed.
Key info:
- Grades: R – 4 (Junior Primary focus)
- Language of instruction: English
- Quintile: Quintile 2 (no-fee school)
- NSNP: Participates
What parents should know: Given the overcrowding reported in 2025, it is worth visiting the school in person before enrolling and confirming placement directly with the principal. Early application (October–November for the following year) gives the best chance of placement.
High Schools in Cosmo City
Cosmo City Secondary School
The flagship high school serving the Cosmo City community. One of the larger secondary schools in northern Johannesburg by learner numbers.
Key info:
- Grades: 8 – 12
- Language of instruction: English

- Matric results: The school has produced matric passes consistently, though pass rates have fluctuated with overcrowding pressures. Parents are encouraged to check the GDE’s annual matric results release (typically January) for the most recent figures.

School safety: A 2025 report on safety and education in Cosmo City highlighted infrastructure and safety concerns at the school. The GDE and Johannesburg Metro Police have been engaged on perimeter security. Parents are encouraged to engage the School Governing Body (SGB) directly for updates.
Contact the SGB: The School Governing Body is the correct point of contact for parents wishing to raise concerns, volunteer, or understand school policies. Contact details are posted at the school’s administrative office.
Pre-Schools and ECD Centres in Cosmo City
Early Childhood Development (ECD) is a growing sector in Cosmo City, with a number of registered and community-run centres serving children from 0–5 years.
What to look for in a Cosmo City pre-school
Registration: The Department of Social Developmen (DSD) registers ECD centres. Always ask to see the centre’s DSD registration certificate. Unregistered centres are not inspected for safety or educational standards.
NSNP participation: Some registered ECD centres in no-fee areas participate in the National School Nutrition Programme. Ask whether the centre receives government nutrition support — this is a sign of proper registration.
Fees: Private ECD centres in Cosmo City typically charge between R600 and R1,800 per month depending on services offered (full day vs half day, meals included, etc.). Community-run and government-supported crèches may charge less.

The Real Situation in Cosmo City Schools — What Parents Should Know
Overcrowding
Cosmo City’s population has grown significantly faster than its school infrastructure. The 92-learners-per-classroom report at Cosmo City Junior Primary in 2025 is an extreme example of a broader pressure: the GDE has acknowledged that the northern corridor of Johannesburg is experiencing a school infrastructure deficit.
What this means practically: Earlier application is essential. The GDE opens applications for the following year in October. Missing this window often means placement in a school outside your preferred zone.
Learner transport
There is no dedicated learner transport service covering all Cosmo City schools. Many families rely on private scholar transport operators — minibus services that run fixed routes between residential extensions and school gates. Prices typically range from R400–R800 per month. If you need help finding a scholar transport operator in the area, post in the My Cosmo City classifieds →.
Safety and school infrastructure
The Cosmo City community has raised school safety concerns in recent years, including perimeter fencing, after-school supervision, and pedestrian safety on routes to school. The Ward 100 councillor and the Cosmo City Community Policing Forum (CPF) are the correct bodies to engage on these issues.
CPF contact: Reach out via the Cosmo City contact page → and we can connect you with local CPF representatives.
