highoakham.co.uk zoominfo.com/c/high-oakham-primary-school/345650404 High Oakham Primary School community primary school in Mansfield, Nottinghamshire — opened September 2001 through the amalgamation of schools during Mansfield's education reorganisation; URN 133278, maintained by Nottinghamshire County Council (not an academy). Size: 464 pupils aged 3–11 (nursery to Year 6, mixed) against a capacity of 428 — over-subscribed, with just 9% free-school-meal eligibility (a relatively affluent intake for Mansfield).

Ofsted (May 2022): "a good school" — English and maths standards above average by Year 6, an excellent start in Reception, teaching "consistently good, some outstanding." Culture: "Be true to yourself,"
