What Arnold House School does

Arnold House School is an independent boys' preparatory school founded in 1905 and located in St John's Wood, central London, operating as a charitable trust overseen by a Governing Board. The school delivers a continuous 10-year educational journey to approximately 180-200 boys aged 3 to 13, structured as a two-form entry across Pre-Reception through Year 8, with tuition fees of £8,081-£10,775 per term depending on year group. Its core academic offering is the Pre-Prep (ages 3-6) and Prep (ages 7-13) programmes, supplemented by a Senior School Transfer programme that prepares boys for entry at 11+ and 13+ to leading UK senior schools including Eton, Harrow, Westminster, and St Paul's, with documented 100% placement outcomes.

The school's distinctive infrastructure includes the Canons Park Activity Centre—a 7.5-acre wholly-owned outdoor facility near Edgware, acquired in 1991 and upgraded in 2005-06—providing weekly outdoor learning, sports, and arts programming that is uncommon among London prep schools. Technology integration centres on third-party adaptive learning platforms (Century Tech, Atom Learning, IXL), digital assessment tools (ISEB), and AI assistants (Microsoft Copilot, Google Gemini) for staff productivity, supported by Firefly Cloud for parent communication. The school employs approximately 53 staff, holds ISI Excellent ratings (September 2025), IAPS and ISC memberships, and a Carnegie Gold Mental Health Award (January 2026).

Arnold House generates revenue almost exclusively through termly tuition fees plus a £180 non-refundable registration fee and £3,000 refundable deposit. It employs a direct-admissions go-to-market model centred on Open Days, a registrar-led application process, and word-of-mouth through its Parents' Association (AHPA) and alumni network (The Arnold Society). Marketing activity is largely organic—website content, Assembly Newsletter, and community partnerships with organizations such as St John's Hospice, Queen's College Prep, and Sarum Hall School. Distribution is single-country domestic (UK), with students drawn from London and the Home Counties.
