About St Mary's Island Church of England (Aided) Primary School
St Mary's Island Church of England (Aided) Primary School sits comfortably above the Medway local authority average for its key stage 2 outcomes. The LA average for pupils reaching the expected standard in reading, writing and maths combined is 62%, while St Mary's achieves 69% — a clear seven-point advantage. This places the school 17th out of 55 primary schools in Medway, putting it in the top third locally. Its ranking score of 69 also puts it within striking distance of the top three schools in the area, which all score 87. The school is noticeably oversubscribed: for 131 applications to its 89 places in the 2025/26 intake, 84 families put it as their first preference, giving an oversubscription ratio of 1.47. That level of demand suggests local parents recognise the school's solid academic performance and its Church of England character, which likely shapes its ethos.
Digging into the 2023/24 key stage 2 results, the picture is one of consistent, above-average performance across the core subjects. In reading, 77% of pupils reached the expected standard and the average scaled score was 106; in maths, the same proportion hit the expected mark with an average score of 105. Writing saw 80% meet the expected standard. At the higher standard, 9% of pupils achieved the top level across all three subjects — a modest but respectable figure. The school's most recent graded Ofsted inspection, in 2014, rated it Good overall, with Good for leadership and management. A subsequent ungraded inspection in November 2023 confirmed the school remains Good. That's a notable improvement from its previous inspection in 2012, which rated it Inadequate. So the school has clearly turned around and sustained a solid standard for over a decade.
St Mary's is a large primary, with 674 pupils against a capacity of 630, meaning it is effectively full. It offers nursery provision for children from age three and has a broad range of facilities including a Forest School, library, ICT suite, art studios and a chapel. Sports provision covers gymnastics, netball, tennis, swimming and athletics, while clubs extend to drama, gardening, choir, film club and chess. The school's SEND provision is comprehensive, covering specific learning difficulties like dyslexia, moderate and severe learning difficulties, social and emotional needs, speech and language issues, hearing and visual impairments, and autistic spectrum disorder. For families seeking a Church of England primary with strong academic results, clear demand from other parents, and a wide range of enrichment opportunities, St Mary's Island is a strong contender within Medway.
