Through excellent work ethic, committed teacher support, and an Emotional Intelligence (EQ) focussed programme, our girls have achieved a 100% pass rate for more than four decades. We teach our girls to believe the best in themselves, and others.

The girls’ final phase of their school career is most important and that’s why at St Mary’s, our committed teaching staff do everything they can to inspire our girls and help them become remarkable women – and the results speak for themselves.

Our Boarding facility, offered from Grade 8 to Grade 12, is a fun, safe, and secure environment which helps foster a strong sense of sisterhood, and gives girls the opportunity to get involved in school activities beyond the classroom.

We instil Christian values, encouraging our girls to nurture and grow their spiritual life through regular Chapel attendance.

The focus is on Healthy Heart, Healthy Mind and Healthy Body, which allows the girls to use all the opportunities at their disposal to ensure they become remarkable women.

High School


Our girls pride themselves in achieving excellence. Our teachers ensure that girls stay motivated and are encouraged to achieve their personal best at all times, in every situation.

We provide a quality education and it’s precisely the reason why we believe in smaller class sizes per grade with a maximum of 25 girls in a class. This ensures every girl receives the attention and support daily that she requires.
