Against South East and Oxfordshire
Track: South East's middle 80% (10th to 90th percentile); L = South East median; O = Oxfordshire median, shown when 10 or more of its schools have a figure; the dot is this school.
South East state schools in Close Knit with a published figure, same phase (primary or secondary) and year; the borough median only when 10 or more of its schools have one. 10th, 50th and 90th percentiles with linear interpolation (PostgreSQL percentile_cont).
Colour only where lower or higher is clearly better (absence: lower): blue = better than the South East median, red = in South East's worst 10%.
Money: Compared only with academies' accounts (AAR), same academic year.
Results
England rank: Key stage 4: Attainment 8 average score. Ranked among 3,280 secondaries in England, 2024/25. England's state-funded mainstream schools with a published figure that year (suppressed or missing figures are left out); equal figures share a rank; top % = rank ÷ schools × 100, rounded up.
Top % in England by year: the first and best years are labelled; the dashed line is the middle (top 50%).
Against South East: South East state secondaries, same year, cohort 30+, suppressed figures left out. Steps: the score out of 10 against South East (10 = top 10%).
Arrows: change in South East percentile points.

Getting in
Got in = first-choice families offered a place on national offer day ÷ families who put the school first. Putting a school first gives no priority: siblings and distance decide.
First-choice applications not offered a place on national offer day: 100 × (1 − first-preference offers ÷ first preferences). Applications count preferences, not children; places can still be offered from waiting lists after offer day.
Source: DfE, Primary and secondary school applications and offers.
Last distance offered: the straight line from the school to the furthest child offered a place under the distance rule. Not a catchment: it changes every year.
Inspections

Dates are the day each inspection started: Dec 2024 Ungraded visit · May 2019 Good · Jan 2017 Requires improvement · Nov 2011 Good · Jan 2009 Satisfactory · Jan 2008 Inadequate. Each dot opens its Ofsted report.
Inspection judgements graded Outstanding or Good, and Requires improvement or Inadequate, out of the judgements graded (the overall grade and aggregated judgements are not counted). Counted from Ofsted's grades, never scored from the report text.
Source: Ofsted, state-funded schools inspections and outcomes.
Pupils
Full = pupils on roll ÷ the school's capacity (1,040 places), from Get Information about Schools.
Pupil profile and absence: DfE school census and pupil absence (Compare school and college performance). Free school meals = eligible at any time in the past 6 years; persistently absent = missed 10% or more of sessions. Withheld = suppressed by DfE.
Parent View
Survey period 3 Sep 2024 to 1 Sep 2025, as at 1 Sep 2025. Source: Ofsted Parent View management information, OGL v3.0 (dataset). The school's own survey page is under Visit & links.
Ofsted changed the survey on 10 Nov 2025. The card shows the newest survey with 10 or more responses; an earlier survey is labelled and never mixed with the current one.
Share of the parents who answered, from Ofsted's published percentages: agree = strongly agree + agree; yes/no and overall-view questions show the share answering Yes or Positive. Where a question does not apply to every parent (Not applicable, I have not raised any concerns), agree is the share of the parents it applies to: strongly agree + agree divided by 100% minus that answer; the card says how many it did not apply to. Don't know stays in. Ofsted publishes a school only with 10 or more submissions. The questions changed on 10 November 2025: the card shows the current survey when the school has one, else the earlier survey (one academic year of submissions, the latest with 10 or more), never both.
Workforce
School workforce census, 2025/26. Staff in FTE (full-time equivalent), rounded to 1 decimal on the card. As published: teachers 54.03, leadership 12, teaching assistants 9.2, support staff incl. TAs 32.77, whole workforce 86.8 (102 people), 61 teachers by headcount.
Other support = support staff incl. TAs minus teaching assistants.
Per adult counts teachers, TAs and other classroom support; excludes admin staff.
- DfE: FTE pupils (January census) ÷ FTE teachers (November census)
- DfE: FTE pupils ÷ FTE teachers, teaching assistants, other school support staff and technicians; administrative, auxiliary and business staff are not counted
- Teachers in leadership posts: head, deputy and assistant heads
Financials
Academy accounts (AAR) · September 2024 to August 2025.
Published total ÷ FTE pupils in the same return, to the nearest pound; income and spend per pupil are left out when the return covers less than 12 months.
CFR (maintained schools, April–March) and AAR (academies, September–August) are different accounts and years: do not compare a maintained school with an academy.
Destinations
Students who finished the stage in the cohort year, followed through the next year: sustained = at least six months in education, an apprenticeship or employment

Independent and selective (grammar) schools choose their pupils, so high results partly reflect who gets in, not only teaching. Some independent schools don't publish results.
