Every published 2024/25 A-level Mathematics value-added score for Bromley's schools and colleges, sourced from DfE's subject-level dataset — plus how our tutors work with Bromley's A-level Maths students.
Book a Free ConsultationBromley is a London borough where the Department for Education publishes a 2024/25 subject-level value-added score for A-level Mathematics at 19 named schools and colleges, out of 25 that return a Mathematics row in DfE's institution-level dataset. Only five of those nineteen scores clear DfE's own statistical bar for a real finding. This page sets out all nineteen, what the data does and does not show, and how Leading Tuition works with Bromley's A-level Maths students.
Our expert A-level Maths tutors help students across Bromley build the pure, statistics and mechanics skills every exam board’s papers test, whichever of the borough’s sixth forms or colleges they attend.
Book a Free ConsultationMessage us on WhatsAppBromley is its own local authority for DfE's purposes, LA code 305, so every school in this borough's sweep sits inside the London Borough of Bromley itself — a reader does not need to wonder whether a school two streets over, in a neighbouring borough, is folded into these figures.
The figures below come from a different Department for Education dataset to the one behind our separate A-level tuition in Bromley page. That page uses DfE's institution-level measure: one progress score per school, covering every A-level subject a student takes together. This page uses DfE's subject-level value-added dataset, which publishes a separate score for Mathematics specifically, alongside its own 95% confidence interval and the number of students matched to prior attainment data. The two measures are not interchangeable, and the all-subject figures on that page are not restated here.
DfE's Bromley sweep for this subject-level dataset returns 27 provider records. Two of them — Baston House School and London South East Colleges, the borough's further-education college — carry no A-level Mathematics row at all in the 2024/25 release; that is a statement about what the dataset contains, not a claim about what either provider teaches. Of the remaining 25, six are suppressed because too few students sat the subject for DfE to publish a figure without risking identifying an individual. The other 19 are published in full, and they appear together in the table further down this page, sorted by how many students each score is based on.
A published score is not automatically a finding. DfE publishes a 95% confidence interval alongside every value-added score, and only when that entire interval sits on one side of zero does the department treat the result as distinguishable from an average outcome. Of Bromley's 19 published Mathematics scores, five clear that bar. The other fourteen, whatever their raw number, are not statistically separable from zero and are not findings on their own.
Interval width is set by cohort size, but a narrow interval is not by itself a finding, and two of Bromley's own scores show why. St Olave's and St Saviour's Grammar School's Mathematics value-added score — DfE's progress measure for that school's 2024/25 A-level entrants, not a measure of teaching quality — is +0.15, with a 95% confidence interval of -0.02 to 0.33 across 191 matched students, the largest matched cohort of any Bromley Mathematics provider in this release. Because that interval still touches zero, DfE would not treat it as distinguishable from an average outcome. Newstead Wood School's score, the same progress measure and the same caveat, is +0.06, interval -0.14 to 0.25, on 149 matched students. A large cohort narrows an interval; it does not by itself push a small effect away from zero.
Bishop Justus CofE School shows the opposite shape. Its Mathematics value-added score — again DfE's progress measure for its 2024/25 entrants, not a measure of teaching quality — is +0.81, with a 95% confidence interval of 0.14 to 1.48 across 13 matched students: a range 1.34 wide, clearing zero at its lower bound by 0.14. A cohort of 13 produces an interval wide enough that DfE's own bar is only narrowly cleared, which is the pattern worth carrying into the table below — the smaller the cohort behind a Bromley score, the more a single year's intake can move it.
DfE's 2024/25 data reflects the school a student attended when they sat their exams in 2025, not necessarily a school that is still open when this page is read. Checking every named Bromley provider in this dataset against the Get Information About Schools register on 27 September 2026 found two that have since closed. Bishop Challoner School, an independent school in Bromley, closed on 4 July 2025, and GIAS records no successor or linked establishment. Kings London, also independent, closed on 27 March 2026. Both remain in DfE's 2024/25 statistics release, because that release covers the academic year in which their students sat exams, not each provider's status as it stood when this page was checked.
The two closures do not affect equally how far a reader can dig. Compare School and College Performance, the Department's own service for looking up an individual school's results, still carries a summary page for Bishop Challoner School noting its closure, but its detailed 16-to-18 subject breakdown no longer resolves at all — checked on 27 September 2026, the same page that lists every subject a school's students sat now returns a Page Not Found error for Bishop Challoner, where it still works for every open Bromley provider. A parent comparing Bromley's sixth forms using either source would be reading at least these two entries for institutions that no longer exist, and would not necessarily know it without checking each provider's status separately, which DfE's own results tables do not do for them.
Six of Bromley's 25 A-level Mathematics rows carry no published score at all. DfE marks a value-added score ‘c’ rather than publishing a number when too few students sat the subject for a figure to be released without risking identifying an individual student, and that is the case at Babington House School, Darul Uloom London School, Harris Academy Orpington, The Tutorial Foundation and Orion Eden Park, plus Kings London — the school named above, which had also since closed by the time this page was checked. None of these six can be compared on this measure at all; a suppressed row is evidence of a small cohort, not evidence of a poor result.
Whichever of Bromley’s sixth forms or colleges your child attends, our A-level Maths tutors work from their own exam board and current working grade, not a borough-wide figure.
Book a Free ConsultationMessage us on WhatsAppThe table below lists all 19 published 2024/25 A-level Mathematics value-added scores for Bromley, sorted by matched cohort size, smallest first, never by score. Reading down it, five of the nineteen have a confidence interval that lies entirely on one side of zero — DfE's own bar for treating a score as distinguishable from an average outcome — and each of the five is stated below with its own interval and matched count, this remaining DfE's progress measure for that school's 2024/25 A-level entrants rather than a measure of teaching quality in every case.
Bishop Challoner School — the closed provider discussed above — carries a Mathematics value-added score of -1.86 for its 2024/25 A-level entrants, DfE's progress measure rather than a measure of teaching quality, with a 95% confidence interval of -2.56 to -1.17 on 12 matched students. Bishop Justus CofE School's 2024/25 score on the same progress measure, not a measure of teaching quality, is +0.81, with a 95% confidence interval of 0.14 to 1.48 on 13 matched students, the illustration used above. Chislehurst School for Girls posted a 2024/25 score of -1.23 on this same DfE progress measure, not a measure of teaching quality, with a 95% confidence interval of -1.75 to -0.72 across 22 matched students. Hayes School's 2024/25 score on the same progress measure, not a measure of teaching quality, is +0.49, with a 95% confidence interval of 0.19 to 0.8 across 63 matched students. Langley Park School for Girls recorded a 2024/25 score of -0.55 on the same DfE progress measure, not a measure of teaching quality, with a 95% confidence interval of -0.89 to -0.22 across 51 matched students.

My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.
We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.
I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.
Not for content. The Department for Education fixes A-level Mathematics subject content nationally, so AQA, Pearson Edexcel, OCR and OCR's MEI-endorsed specification all teach the same pure, statistics and mechanics topics — the boards differ only in how they structure their papers, which paper carries which applied content, and how marks are split between them. Our full paper-by-paper comparison, board by board, is on our dedicated A-level Maths page. What matters for a Bromley family before revision starts is knowing which specification their own sixth form or college has actually entered them for — that is worth confirming with the school directly rather than assuming from a neighbouring school's choice.
Every Bromley A-level Maths programme begins with a short diagnostic session against a student's own exam board, current working grade and target, rather than a fixed checklist, so a tutor can see immediately whether the priority is closing a content gap in mechanics or statistics, building exam technique under timed conditions, or working towards a specific grade threshold for a university offer. Our tutors hold degrees from leading UK universities, and each one working with a Bromley student is chosen for their subject, exam board and year group, not simply for their availability.
Sessions run one-to-one online with a shared whiteboard, letting a tutor work through past-paper questions, mark answers against the real mark scheme, and share annotated resources in real time — the same working method whether a student attends St Olave's, Newstead Wood, one of Bromley's Harris academies, or any other Bromley sixth form, college or independent school. Progress is reviewed against a student's own target grades at agreed intervals, and session notes are shared with parents after each lesson so support at home lines up with what happened in the tutorial. Families with a younger child facing 11+ or 13+ entry can see our wider tutoring across Bromley coverage.

All value-added figures above are drawn from the Department for Education's institution-level subject value-added dataset, A-level Mathematics, 2024/25 academic year, read via the Explore Education Statistics API on 27 September 2026. School status checked against Get Information About Schools on 27 September 2026.

Yes. Bromley is local authority 305 in DfE's own coding, and every provider in this page's sweep sits inside the London Borough of Bromley itself. That is different from three neighbouring towns on this site's location pages, such as Twickenham or Wimbledon, which sit inside a larger local authority (Richmond upon Thames and Merton respectively) and need their own separate coverage rule. A family checking a Bromley school does not need to wonder whether a provider from outside the borough has been folded into these figures.
It is DfE's progress measure for a school's A-level Mathematics entrants in a single academic year — 2024/25 in every figure on this page — comparing their actual results against the results nationally of students with similar prior GCSE attainment. It is not a measure of teaching quality on its own, and it is a different DfE dataset from the all-subject progress score already published on our separate A-level tuition in Bromley page, which covers every A-level subject together rather than Mathematics specifically.
Two reasons, and they are different. Six of Bromley's 25 provider records — Babington House School, Darul Uloom London School, Kings London, Harris Academy Orpington, The Tutorial Foundation and Orion Eden Park — have too few A-level Mathematics students in 2024/25 for DfE to publish a score without risking identifying an individual, so each is marked suppressed. A further two providers, Baston House School and London South East Colleges, return no Mathematics row in the dataset at all, which is a statement about what the dataset contains rather than a claim about what either provider teaches.
No. Checking DfE's 2024/25 dataset against the Get Information About Schools register on 27 September 2026 found two named Bromley providers that have since closed: Bishop Challoner School, closed 4 July 2025, and Kings London, closed 27 March 2026. Both remain in the 2024/25 statistics release because it covers the academic year their students sat exams in, not each provider's current status, so a reader working from this data alone would not know either school had closed.
It makes the score less precise, which is not quite the same thing. Bishop Justus CofE School's 2024/25 Mathematics value-added score — DfE's progress measure for that year's entrants, not a measure of teaching quality — is +0.81 with a 95% confidence interval running from 0.14 to 1.48 on 13 matched students, a range 1.34 wide. St Olave's and St Saviour's Grammar School's score, the same measure, is +0.15 with an interval of -0.02 to 0.33 on 191 matched students, a much narrower range. A smaller cohort behind a score means a single year's intake can move it considerably more than it would for a school with hundreds of matched students.
It varies by school, and DfE's subject content is fixed nationally regardless: AQA, Pearson Edexcel, OCR and OCR's MEI-endorsed specification all teach the same pure, statistics and mechanics topics, differing only in paper structure. Our A-level Maths page carries the full board-by-board comparison; confirming which specification a particular Bromley sixth form has entered a student for is worth doing directly with the school.
