What St George's School Windsor Castle does

St George's School Windsor Castle is a private co-educational preparatory school, registered as a charity in England and Wales (charity number 1100392, company number 04347052), with origins dating to 1348 when it was founded by King Edward III as part of the College of St George to educate the choristers of St George's Chapel at Windsor Castle. The school operates on Crown land at the foot of Windsor Castle in Windsor, Berkshire, serving approximately 300 day and boarding students from Kindergarten (age 3) through Year 8 (age 13), including a chorister cohort of up to 23. It is the first standalone UK prep school accredited to deliver the International Baccalaureate Primary Years Programme (PYP, accredited 2023) and the first standalone UK prep to join the Round Square global network.

The school's core product is a 3-13 Learner Journey curriculum organised across four phases: Early Years Foundation Stage (Kindergarten), Pre-Prep (Years 1-3), Prep School (Years 4-6), and Senior Prep (Years 7-8) with the Pre-Senior Baccalaureate framework. Teaching is supported by a 1:1 Chromebook programme from Year 3, a digital learning curriculum using Espresso Discovery Coding, Scratch, Kodu, and Code Academy, plus specialist performing arts, sport, design faculty (with 3D printer and CAD), and a MindUp mindfulness programme dating to 2003. Boarding is offered from Year 4 as weekly or flexi boarding, with ~23 choristers forming the Chapel choir. The school holds IB World School status, Round Square membership, ISI compliance (all standards met, November 2025), and Eco-Schools Green Flag, and has been listed in Tatler Schools Guide for seven consecutive years and the top 100 of Spear's 500 Schools Index in 2025.

Revenue is generated primarily through termly tuition fees (subscription, recurring) ranging from £3,089/term for Kindergarten mornings to £11,162/term for weekly boarding, with 2026/27 Year 5-8 day fees at £8,980/term. Additional revenue streams include flexi boarding at £68/night, after-school care (£5-£17/session), breakfast and supper clubs, a £75 non-refundable registration fee and £750 deposit, mean-tested music scholarships funded by the Andrew Lloyd Webber Foundation, and alumni life membership subscriptions. The school sells directly to families with no resellers, via open events, personal tours managed by a dedicated Registrar, and a Taster Day admissions process. In April 2026, the school announced it will join the St Albans Education Group (STAEG) in Summer 2026 and partner with St George's Ascot to create a new co-educational through school (St George's School, Windsor and Ascot).

Direct peers

• Cheam School: Historic co-educational prep school (age 3-13) in Headley, Hampshire, with day and full boarding. Long-standing destination-school pedigree (Eton, Harrow, Benenden) and similar 'heritage prep' positioning in the South East.
• Caldicott School: Independent day and boarding prep school for boys aged 7-13 in Farnham Royal, Buckinghamshire. Overlaps with St George's on Eton/Harrow destination outcomes and on the prep-day-plus-flexi-boarding model.
• Ludgrove School: Long-established boys' boarding prep school (age 8-13) in Wokingham, Berkshire, known for sending large cohorts to Eton and Harrow. Overlaps directly with St George's on senior-school destination outcomes and Berkshire catchment geography.
• St John's Beaumont School: Independent preparatory school for boys aged 3-13 located in Old Windsor, Berkshire, in close proximity to St George's. Operates a similar day-and-boarding model, tracks pupils to Eton, Harrow, and other senior schools, and competes head-to-head in the Windsor catchment.
• Lambrook School: Co-educational prep school in Bracknell, Berkshire, catering to children aged 3-13 with day, flexi, and full boarding. Comparable in age range, fee tier, and destination-school positioning, competing directly for Berkshire-based prep families.
• Cothill House: Small, prestigious boys' prep boarding school (age 8-13) in Abingdon, Oxfordshire. Comparable in scale, fee tier, and senior-school destination profile, operating in the broader South East prep market.
• Papplewick School: Independent preparatory school for boys aged 6-13 (with a co-ed Pre-Prep) in Ascot, Berkshire. Offers day and weekly boarding, and routes pupils into leading senior schools such as Eton, Harrow, and Wellington — closely matching St George's value proposition.
• Summer Fields School: Leading boys' boarding prep school (age 8-13) in Oxford with a long track record of preparing pupils for Eton, Harrow, and Winchester. Comparable in heritage, boarding-centric model, and Oxbridge-region prep positioning.

Broad incumbents

• The King's School, Canterbury Junior School: The previous employer of St George's current Head, Emma Károlyi. While the Junior School itself is a direct prep peer, the wider King's School encompasses a full K-13 offering, making the overall institution a broader incumbent in the senior-school destination space relevant to St George's families.
• Eaton House Schools: Group of premium London-based independent prep schools (The Manor, Belgravia, Eaton Square, etc.) serving high-net-worth families across multiple age ranges. Operates at a comparable premium price point and prepares pupils for top senior schools, but as a multi-campus group rather than a single-site heritage school.
