About Grimsdyke School

Grimsdyke School in Harrow has been rated Outstanding by Ofsted across every category in its most recent inspection in 2023, a clean sweep that includes quality of education, behaviour and attitudes, personal development, and leadership and management. This is a school that has clearly sustained high standards over time — its previous inspection in 2011 also awarded an Outstanding overall rating. On the most telling academic metric for a primary, the proportion of pupils reaching the expected standard in reading, writing and maths combined at Key Stage 2, Grimsdyke sits at 81 per cent. That is comfortably above the Harrow local authority average of 72 per cent, and it places the school 12th out of 38 primaries in the borough. In national terms, it sits in the top 10 per cent of all primary schools in England, a strong indicator of consistent classroom performance.

Digging deeper into the 2023/24 Key Stage 2 results, the school’s strengths become clearer. In reading, 87 per cent of pupils hit the expected standard and half reached the higher standard, while in maths 87 per cent met expectations and 57 per cent achieved the higher threshold. Writing saw 90 per cent at the expected level, though the proportion reaching the higher standard was lower at 19 per cent. Average scaled scores were 108 in reading and 109 in maths, both above the national benchmark of 100. The school does not publish progress scores, so it is not possible to say how much value it adds relative to pupils’ starting points, but the raw attainment figures are strong. In Harrow, Grimsdyke ranks 11th overall among the 41 state primaries, and it is one of ten schools in the borough currently holding an Outstanding Ofsted rating. The nearest other Outstanding primary is Pinner Wood School, about 1.7 kilometres away.

Grimsdyke is a large primary with 628 pupils on roll, operating very close to its capacity of 630. It is heavily oversubscribed: for the 2025/26 reception intake, there were 298 applications for 88 places, giving an oversubscription ratio of 3.39. Of the 88 first-preference applicants, 73 received offers. The school is led by headteacher Bindiya Bhudia and has no religious character. Facilities include a sports hall, library, ICT suite, playing fields, art studios, music rooms and a chapel. The sports on offer cover football, cricket, dance, netball, tennis and rounders, while clubs include drama, eco club, film club and coding. For families with children who have additional needs, the school lists a wide range of SEND provisions, including support for autistic spectrum disorder, speech and language difficulties, dyslexia, and social, emotional and mental health needs. This is a school that suits families looking for strong academic outcomes in a well-equipped, popular setting where demand far outstrips supply.
