School History

St Mary’s Diocesan School for Girls is situated in the rolling hills of Kloof, KwaZulu Natal and was founded in 1906.

Established by the nuns of the Order of St John the Divine, an Anglican Sisterhood, the school was initially named St Elizabeth’s High School in honour of Elizabeth Field.

The Fields owned the land that stretched from Clermont in the South-East to Botha’s Hill in the West – typically where Kloof now resides. A portion of the Fields farm was donated for the establishment of a school for girls. It closed its doors in 1919 as St Elizabeth’s and re-opened as St Mary’s DSG.

The Honourable Frederick Samuel Baines, Bishop of Natal, opened St Mary’s DSG in Kloof on 3rd September 1919. The service was held in the Hall, a large barn-like construction, one of several wood and iron buildings on the property. The school chapel was also a wood and iron relic from the Anglo-Boer War (1899-1902), purchased from the Princess Christian Hospital at Sarnia and moved with the nuns from its original site on Field’s Hill.

St Mary’s welcomed 30 pupils in its first year, 2 of them boys too young to be enrolled in the local boys’ boarding school. For many years, St Mary’s DSG continued to enrol boys in classes I and II.

From humble beginnings, we take pride in the leading academic school that St Mary’s has become and are committed to our vision to be the leading Christian school providing a holistic, values-based education that helps girls build their character, curiosity for learning and equipping them to thrive in life.

What facilities do Junior Primary girls use?

What is Emotional Intelligence (EQ) and what are the benefits?

Emotional Intelligence (known as emotional quotient or EQ) is the ‘ability to understand, use, and manage emotions in positive ways’. Focusing on building a high EQ in our girls at St Mary’s will help them to communicate better, bounce back when faced with challenges and adversity and work better and empathise with others.

What is a Growth Mindset?

Growth Mindset is based on the belief that intelligence can be developed, we are constantly learning. The way in which we view failure and mistakes is important. Our girls are reminded that mistakes are not bad, but merely signposts that they are learning. We provide a safe environment in which they are able to challenge themselves without the fear of failure.

What is the Social Emotional Learning strategy?

Through developing Emotional Intelligence skills and understanding our school values, our girls refine their ability to function well socially and within themselves. Our teachers attend workshops around emotional growth and development and integrate these ideas into their programme. As a school, we follow research in this area as it is considered to be essential in the modern era, given the diverse workplaces and the impact that technology has had on society.

How do we integrate our new Grade R/Little Saints girls into the St Mary's family?

When the girls start at St Mary’s, each little girl becomes part of a ‘Saints Sisters‘ family group. These groups meet a few times during the year and this provides a wonderful opportunity for the girls to build relationships and for the older girls to mentor and nurture the younger girls.

Each Little Saints girl has a Grade 7 buddy. They meet for the first time at Orientation Day and then share special time together during the year. This helps to integrate the Little Saints girls into the life of St Mary’s and helps them feel welcome and a part of the family!

Each class has a Grade 7 and Grade 12 ‘Big Sister’, who spends time in the classrooms either in the morning before school or at snack time. The younger girls just love engaging with these ‘Big sisters’ and it’s heart-warming to see them connecting with one another.

What is Emotional Intelligence (EQ) and what are the benefits?

Emotional Intelligence (known as emotional quotient or EQ) is the ‘ability to understand, use, and manage emotions in positive ways to relieve stress’. Focusing on building a high EQ in our girls at St Mary’s will help them to communicate better, rise above challenges, work better and empathise with others.

How is technology introduced in this phase?

In Senior Primary, we regard technology as an integral part of the programme and not just as an add-on subject. Each girl from Grade 4 has her own iPad which is used to enhance the type of activities undertaken. The girls create their own movies, presentations, mindmaps, as well as do their research. Girls have weekly ICT lessons where they are taught digital skills, but the skills are integrated and augmented wherever possible in each subject. Coding and robotics have been introduced and will be taught through our integrated, enquiry-based learning curriculum as well as our Robotics Club.

How can girls in this phase express their creativity?

Not only do the girls have weekly Music, Drama and Art lessons, but they are able to join a wide variety of music ensembles and choir. We have a bi-annual Grade 6 and 7 play, alternating with a Speech and Drama festival as well as other cultural evenings. Every fortnight, each grade is able to spend a day in the Creativity Centre where the programme will focus on integrated learning with a variety of activities. This is always a highlight for each girl.

What facilities do the girls in the Senior Primary phase have access to?

How many subjects are offered?

What is the Matric pass rate at St Mary’s?

We have had 100% Bachelors pass rate for many years with an average of 3-4 distinctions per pupil.

What leadership and mentorship opportunities are available for High School girls?

In Matric, each girl has a leadership portfolio which is monitored and supported by a teacher. The girls receive feedback during the course of the year and are acknowledged accordingly at the completion of their Matric year. There are many leadership roles in each year of high school ranging from sports roles to cultural and Chapel roles.

How do we develop our girls’ character during this phase?

Teenager’s learn best about themselves through experiential learning. By having outdoor education programmes, community projects and outreach, leadership opportunities and high standards, our girls learn to plan, persevere and to take life one day at a time.

What is the 21-day Journey about?

Research underscores the importance of the skills, beliefs and behaviours that support achievement in the classroom and beyond. This set of traits includes perseverance, grit, problem-solving, social skills, efficacy beliefs and mind-sets which are not measured directly by traditional academic assessments. These play an enormous role in both academic and personal success. Outdoor adventure education enables the growth of these traits which cannot be developed effectively in a theoretical or traditional classroom environment.

Are extra lessons available? If so, what subjects are offered?

There are support lessons run every afternoon of the week and girls may sign up for these and request on specific areas. Different subjects are offered on different days to accommodate the sports and cultural programmes.

I’ve heard about an International Exchange Programme. Tell me more about this.

We have exchange programmes with schools in Australia and Germany. This is an area which we would like to grow.

How does a St Mary’s Matric pass differ from other schools?

Not many schools can say they have had 100% pass rate for almost 50 years and that for more than the past 10 years, a 100% Bachelors pass rate.

What pastoral opportunities are available to aid my daughter’s spiritual growth?

Confirmation classes from Grade 10. Christian fellowship meetings; God girls (Bible study group and prayer group); 3 Chapel services every week; Outreach and Community Projects. There are also Chaplain’s lessons for the Grade 8 – 10s.
