6th of 15 secondary schools in Sutton 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 — 9.3/10 against 693 of them, against 9.4/10 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.
How this is worked out
| Measure | Percentile | Weight | Adds |
|---|---|---|---|
| Ofsted | 87 | 35% | 3.05 |
| Grade 5+ English & maths 2025/26 | 80.4 · 94 | 30% | 2.83 |
| Progress 8 2023/24 | 0.75 · 93 | 25% | 2.32 |
| Attainment 8 2025/26 | 63.6 · 95 | 10% | 0.95 |
Each measure is read as a position among comparable schools, so a school in the middle of the country scores 5. Full method.

How it's doing
In 2024/25, 75.2% of pupils achieved grade 5 or above in English and maths. Attainment 8 was 61.6, compared to the national median of 44.6. Progress 8 was +0.75 in 2023/24, indicating better progress than pupils nationally starting from the same place. Its results hold up when the comparison narrows to schools whose pupils have similar backgrounds, so they are not simply a reflection of who attends (9.1 out of 10 against similar schools, 9.3 out of 10 against all schools). Ofsted inspected the school in January 2026 under the new framework, which grades areas separately without an overall grade.

What Ofsted said about Glenthorne High School
Overview
The report describes a school where leaders have created a "highly inclusive culture" that enables pupils to flourish. It highlights "exceptional" inclusion and personal development, alongside "strong standard" achievement, attendance, and teaching. The inspection concludes that pupils are "well prepared to succeed beyond school" in a "harmonious community."
Strengths
- Inclusion is rated "Exceptional," with "highly personalised support" ensuring vulnerable pupils and those with special educational needs "flourish" and secure "superb academic outcomes."
- Personal development is "Exceptional," featuring a "first class" programme that fosters "tolerance, respect" and an "uncommonly extensive programme of cultural and creative opportunities."
- Achievement is rated "Strong standard," with pupils achieving "significantly above national averages" at GCSE and developing "deep, rich knowledge" through a "highly ambitious, well-sequenced curriculum."
- Attendance and behaviour are "Strong standard," characterised by "consistently high" attendance and "calm and orderly" classrooms where learning is "free from disruption."
- Leadership is "Strong standard," with governors providing "high-quality oversight" and leaders prioritising staff wellbeing and the needs of vulnerable pupils.
Areas to improve
- Leaders should "sustain the effectiveness" of their work in inclusion and personal development, which currently has a "transformational impact."
- Leaders should "continue to further strengthen other high-performing areas" so they have an "equally positive impact" on pupils’ experiences.
Safeguarding
The safeguarding standards are met, with an "open culture in which safeguarding is everyone's responsibility" ensuring that concerns are "actively identified, acted upon and managed" so that "pupils are made safer and feel safe."
