Ofsted: Good · 2023 Inspected 3 years ago Mixed Secondary
3.6/10 Broadly average

13th of 13 secondary schools in Harrow we can score. Local and same-phase on purpose: a national table mostly measures who attends.

Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds — 2.6/10 against 827 of them, against 2.7/10 nationally. So this is not simply a reflection of who attends. Both figures are results only, without the inspection grade. A lower figure here means a stronger comparison group, not a weaker school.

Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

Canons High School overview

How it's doing

In 2024/25, 35.2% of pupils achieved Grade 5 or above in English and maths. Attainment 8 was 39.1, compared to the national median of 44.6. Progress 8 was -0.07 in 2023/24, indicating pupils did slightly worse than those nationally who started from the same place. Its results are much the same when the comparison narrows to schools whose pupils have similar backgrounds, so the gap is not explained by intake (3.7 out of 10 against similar schools, 3.3 out of 10 against all schools). Ofsted rated the school Good in March 2023.

What Ofsted said about Canons High School

Inspection report dated 15 March 2023

Overview

Canons High School is rated as ‘Good’ across all inspection categories, marking an improvement from its previous ‘Requires improvement’ judgement. The report describes an inclusive environment where pupils feel valued and enjoy strong relationships with staff who actively support their success. Leaders have established an ambitious curriculum that helps most pupils build secure long-term knowledge, though inconsistencies remain in specific subjects.

Strengths

  • Teachers demonstrate subject expertise and use regular recall activities to help pupils “build and remember long-term key knowledge.”
  • Pupils benefit from a “comprehensive, impartial careers guidance programme” and opportunities for work experience.
  • Staff provide “bespoke support” for pupils behind in reading, which is “beginning to help pupils to get back on track.”
  • The school offers a wide range of enrichment activities, including astronomy, chess, and sporting clubs.
  • Staff workload is described as “reasonable,” with senior leaders being “approachable” and caring for staff welfare.

Areas to improve

  • Leaders must ensure they “identify precisely what key knowledge they want pupils to know and remember” in subjects where curriculum sequencing is currently lacking.
  • Staff need to make “suitable enough adaptations to teaching and resources” to fully meet the needs of pupils with SEND or EAL, ensuring they do not disengage.
  • Leaders should refine strategies to help a small group of pupils with “extremely challenging behaviours” manage their conduct, particularly during social times.

Safeguarding

The report states that “the arrangements for safeguarding are effective,” noting that staff receive regular training, recognise risks, and make timely referrals to external agencies.
