Best High Schools in Gauteng

1 | St John’s College – Johannesburg

2 | Roedean School (SA) – Parktown

Private • Girls • Day & Boarding

Tuition 2025: Grades 10‑12 — R218 877; Grades 8‑9 — R198 850 schoolhive.co.za

3 | Parktown Boys’ High School – Johannesburg

Public • Boys • Day & Boarding

Tuition 2025: ± R65 000

Private • Catholic • Boys • Day & Boarding

Tuition 2025 (Gr 10‑12): R174 114
Boarding (annual): R128 199 termly / R120 100 weekly stbenedicts.co.za

Public • Boys • Day & Weekly Boarding

Cricket legends are born here, and the Red Army rugby crowd is the stuff of Gauteng folklore. Weekly boarding fills fast—apply by Grade 6!
