Welcome to
St. Mary's Preparatory School

We have been at the centre of education in Henley for almost 100 years, helping generations of children to learn in a stimulating and inspiring environment. Situated in the heart of the town in a beautiful Victorian townhouse, our vibrant co-ed prep school provides an outstanding education for children aged 3 – 11 years.

Proud of our reputation for delivering academic excellence – the attainment of St. Mary’s pupils is above national age-related expectations in all subjects, and our more able pupils are challenged and stretched with a range of classroom work and additional activities.

Our pupils are well prepared to make the transition on to the next stage in their education, with children consistently receiving offers from their first choice of the most prestigious schools in the area, including scholarships and awards.


Inspection Report 2023

We are proud to have been awarded the highest possible grade: double EXCELLENT in our recent ISI Inspection.

As well as being fully compliant in every aspect of the Regulatory Compliance Inspection, it was determined that the children’s academic achievement is "Excellent" and the children’s personal development is "Excellent".


We prioritise personalised education with small class sizes, ensuring that each child receives individual attention, tailored support, and the opportunity to excel academically at their own pace.


Our school’s location in beautiful Henley on Thames, enables us to access a wonderful variety of outdoor learning spaces with our children. From woodlands and wildlife gardens to the River Thames, we offer unique opportunities for experiential learning.


Our close-knit community is a cornerstone of our educational journey. Here, teachers, children, and parents come together as active participants, each with a voice in shaping our school's excellence.

Nurturing excellence
in the heart of Henley

Our outstanding onsite facilities are enhanced by excellent sports and outdoor options in Henley-on-Thames and the local area.

Our specialist classrooms such as a fully equipped science lab, light and airy art studio, music room and vibrant well stocked library, foster a dynamic learning environment. Our wonderful outdoor spaces include a recently refurbished courtyard playground and all-weather sports area, climbing frame and soft surface. Our Nursery and Early Years children also benefit from their own specialist fun and interactive outdoor area in addition to the main school facilities.

Laptops, iPads and interactive whiteboards, in our classrooms, all connected through our school-wide wireless network, promote interactive learning.

We have close relationships with a number of local organisations, enabling us to provide our pupils with exciting learning environments, all just a short walk or minibus journey away.

It is Empathy Day today, a reminder to all of the value of kindness, mutual support and understanding in schools.

We are very proud of our reputation for providing a highly nurturing environment for all of our children, and we know that happy children make the best learners. 

The assembly with former children's laureate Michael Rosen this morning included his Empathy Resolution and plans for a Mission Empathy Challenge!

This afternoon, children will be taking part in a drawing workshop with one of their favourite illustrators, Rob Biddulph, learning how to draw a Karma Llama!

Our ISI Inspection report noted that: "Pupils of all ages are strongly socially aware, engendered by the family ethos that permeates the school.  Pupils help each other and work collaboratively. Pupils are kind and generous in attitude."

For all of us at St. Mary's, empathy is important every day.
