About Threemilestone School
Threemilestone School, a state primary in Cornwall, holds a Good rating from its most recent Ofsted inspection in 2024, but the detail behind that grade tells a more interesting story. Inspectors judged the school’s personal development as Outstanding, the highest possible mark, while quality of education, behaviour and attitudes, leadership and management, and early years provision were all rated Good. On the key academic metric for primary schools, 79% of pupils met the expected standard in reading, writing and maths combined in the 2023/24 Key Stage 2 assessments. That is well above the Cornwall local authority average of 58%, and it places the school 17th out of 208 primaries in the county, comfortably inside the top 10% nationally. The school also achieved a ranking score of 79, putting it in the top 25% of schools across England.
Digging into the exam data a little further, Threemilestone’s pupils performed particularly strongly in reading and writing, with 84% reaching the expected standard in each subject. Maths was close behind at 80%. At the higher standard, 30% of pupils achieved a high score in maths, compared with 20% in reading and 15% in writing. Average scaled scores of 105 in both reading and maths are solid, though the school does not publish progress scores for these subjects. The proportion of pupils reaching the higher standard across all three subjects was 8%, which is in line with national expectations. With 15.5% of pupils eligible for free school meals, the school serves a slightly above-average proportion of disadvantaged children for the area, yet its outcomes remain strong relative to other Cornwall primaries.
The school is oversubscribed: for the 2025/26 academic year, it received 69 applications for 47 places, with 45 first-preference offers made. Facilities include a library, sports hall, gymnasium, ICT suite, sensory room and playing fields, plus a chapel. Clubs on offer include art, book and gardening, while sports range from dance and gymnastics to netball and rounders. The school’s SEND provision covers a wide spectrum, including specific learning difficulties, speech and language needs, hearing and visual impairments, physical disability, and autistic spectrum disorder. Parent feedback from the most recent Parent View survey was very positive: 89% of respondents would recommend the school, and 94% agreed or strongly agreed that their child is happy there. This is a school that combines strong academic results with a clear focus on personal development and a broad range of activities.
