Harrow's 2025 GCSE results, school by school, sourced from DfE data — plus how our tutors work with Harrow GCSE students, including those sitting IGCSEs.
Book a Free ConsultationMy 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.
Leading Tuition provides GCSE tuition in Harrow, a London borough where state-funded schools achieved an average Attainment 8 score of 51.1 in the 2025 GCSE results, against an England average of 46.1. Harrow's rate of pupils reaching grade 5 or above in English and maths GCSEs was 53.6% that year, against 45.4% nationally. This page sets out those figures school by school, including three independent schools DfE cannot fairly score, and how our tutors work with Harrow GCSE students.
Harrow's 2025 results, covering the 2024/25 academic year and based on grades announced on 21 August 2025, place the borough above the England state-funded average on every headline measure the Department for Education publishes, though below Outer London's own regional maximum. The table below sets Harrow's figures against England's state-funded schools, England's schools overall, and the highest-scoring English regions on each measure in 2025.
| Area | Attainment 8 (2025) | Grade 5+ English & Maths (2025) | EBacc Entry (2025) | EBacc APS (2025) |
|---|---|---|---|---|
| Harrow | 51.1 | 53.6% | 66.6% | 4.72 |
| England - state-funded schools | 46.1 | 45.4% | 40.5% | 4.09 |
| England - all schools | 43.8 | 41.8% | 36.7% | 3.85 |
| Outer London (highest region, this measure) | 50.8 | 53.8% | not published for this region | 4.64 |
| Inner London (highest region, this measure) | not published for this region | not published for this region | 57.1% | not published for this region |
Outer London recorded the highest Attainment 8 score (50.8) and grade 5+ English & maths rate (53.8%) of any English region in 2025; Inner London recorded the highest EBacc entry rate, at 57.1%. DfE's regional summary reports only the minimum and maximum local authority or region for each measure, not a full profile for every region, so the cells marked "not published for this region" above are absent from that source table rather than genuinely zero. Nationally, the local-authority range for Attainment 8 ran from 34.4 in Knowsley to 59.3 in Sutton in 2024/25 - Harrow's 51.1 sits in the upper half of that range. 2025's EBacc entry rate of 40.5% nationally was itself the highest recorded since the measure was introduced in 2010.
One measure is missing from that table by design. Progress 8 - which measures how much progress pupils make between key stage 2 and their GCSEs - cannot be published for 2025. The Department for Education states this directly: "It is not possible to calculate Progress 8 for academic years 2024/25 and 2025/26. This is because there is no KS2 prior attainment data available to use to calculate Progress 8 when the relevant cohorts reach the end of KS4 as primary tests and assessments were cancelled in academic years 2019/20 and 2020/21 due to COVID-19 disruption." The last year a Progress 8 score could be calculated was 2024, a full year behind the Attainment 8 and grade 5+ figures above. Harrow's 2024 Progress 8 score was 0.46 - against an England state-funded average of -0.03 the same year. Any local page still quoting a 2025 Progress 8 figure for a Harrow school is quoting a number DfE has said it cannot produce; the school-by-school table below marks every Progress 8 figure 2024, one year behind its Attainment 8 neighbour, for exactly this reason.
Harrow's borough-wide figures are an average across 22 secondary schools and colleges of every type, maintained, academy and independent. The decision a family is usually weighing is about one specific school, so the table below sets out named, DfE-published figures for the thirteen Harrow state-funded secondaries with results substantial enough to publish across Attainment 8 and grade 5+ English & maths from the 2025 results, alongside Progress 8 from 2024, the last year DfE could calculate it - plus Harrow's three best-known independent schools, marked with an asterisk. Schools are ordered by their 2025 Attainment 8 score.
| Harrow Secondary School | Attainment 8 (2025) | Grade 5+ English & Maths (2025) | Progress 8 (2024) |
|---|---|---|---|
| Avanti House School | 64 | 73.9% | 1.1 (well above average) |
| Nower Hill High School | 59 | 67.8% | 0.62 (well above average) |
| Bentley Wood High School | 58.5 | 62.4% | 0.9 (well above average) |
| The Sacred Heart Language College | 57.9 | 59.7% | 0.56 (well above average) |
| Pinner High School | 57.1 | 69.7% | 0.71 (well above average) |
| Whitmore High School | 55 | 56.5% | 0.75 (well above average) |
| Salvatorian Roman Catholic College | 54.1 | 58.5% | 0.45 (above average) |
| Park High School | 48.9 | 49.0% | 0.17 (average) |

| Hatch End High School | 43.9 | 38.9% | -0.03 (average) |
| Whitefriars School | 43 | 45.6% | -0.1 (average) |
| Rooks Heath School | 40.7 | 36.0% | 0.32 (above average) |
| Canons High School | 39.1 | 35.2% | -0.07 (average) |
| Harrow School* | 24.9* | 0.0%* | NP (not published) |

| The John Lyon School* | 13.7* | 0.0%* | NP (not published) |
*North London Collegiate School and The John Lyon School enter their core GCSE subjects - Maths, English and the sciences - as IGCSEs outright; Harrow School's own site uses the notation "(I)GCSE" for the same subjects. None of these count toward DfE's Attainment 8, grade 5+ or EBacc measures. The three starred figures above are a gap in what DfE's dataset covers, not a measure of how these schools' pupils actually perform. The next section explains the mechanism in full and shows each school's own published results for the same year.
For comparison, Harrow's own borough-wide average was 51.1 for Attainment 8 (2025), 53.6% for grade 5+ English & maths (2025) and 0.46 for Progress 8 (2024). Unlike Barnet or several neighbouring boroughs, Harrow has no state grammar schools, so every state-funded school in the table above is non-selective; the spread between them is examined in full further down this page.
DfE's Attainment 8 measure is built from eight qualification slots - English and maths, each double-weighted, three further EBacc subjects, and three further open slots - using only qualifications on DfE's approved list for performance measures. Harrow School, North London Collegiate School and The John Lyon School each show a grade 5+ English & maths rate of 0.0% and an EBacc entry rate of 0.0% in the 2025 data, not because no pupils sat English, maths or science, but because none of those entries appear on DfE's approved list. Each school's own "subjects entered at key stage 4" page on the DfE service lists only subjects from outside that core - Latin, Religious Studies, Art and modern languages, and at two of the three a humanity as well: Geography at Harrow School, History at North London Collegiate School - with DfE's own note that "this list only includes qualifications approved for inclusion in the performance measures."
Each school's own website explains what fills that gap. Harrow School's Curriculum page states that "in some subjects, such as English, Mathematics and the Sciences, boys begin their (I)GCSE on their first day of lessons," and that boys take the whole Remove and Fifth Form curriculum "as (I)GCSEs." North London Collegiate School's Academic page is more specific still, listing English Language, English Literature, Mathematics, Biology, Chemistry and Physics as compulsory Years 10 & 11 courses, each labelled "(IGCSE)" in full. The John Lyon School's Academic Subjects page does the same for Years 10 and 11, naming English Language, English Literature, Mathematics, Biology, Chemistry, Physics, Geography and History all as "(IGCSE)." For North London Collegiate School and The John Lyon School, whose own pages state "IGCSE" outright, that qualification sits outside DfE's approved list for these performance measures, which is why their core-subject results do not reach the DfE figures. Harrow School's own wording is less explicit - "(I)GCSE" denotes GCSE or IGCSE depending on the subject - but its DfE "subjects entered" page confirms the same outcome by absence: no GCSE in Maths, English or a science appears there at all - only a Level 3 Additional Mathematics FSMQ, which is not a GCSE and does not fill an Attainment 8 maths slot - and any such qualification on DfE's approved list would. Whatever Harrow School's pupils sit in those subjects, it is not on that list, which is what produces its Attainment 8 score of 24.9.
That these are data artefacts rather than weak results is confirmed by what each school reports about its own pupils. Harrow School's own results release, published 21 August 2025 - the same cohort year as its DfE Attainment 8 score of 24.9 - reported that "over 40% of grades were graded 9, with two-thirds of grades graded 9 or 8." North London Collegiate School's results release the same day reported "a stunning 83.4% of all grades were awarded at grade 9," 95.9% at grade 9 or 8 and 99.2% at grade 9 to 7 - its best results on those measures since numerical grading began in 2018, against a DfE Attainment 8 figure of 19.9. Read plainly: DfE's website does not measure these three schools' actual results, because those results are not in the dataset it draws from. All three schools also show "NP" - not published - against Progress 8 for 2024, a separate gap in the same dataset.
Because Harrow has no state grammar schools, the spread across its named secondaries sits entirely among non-selective academies and one maintained school, with no academic entrance test dividing them. Avanti House School's 2025 Attainment 8 score of 64 and Canons High School's score of 39.1 are 24.9 points apart - coincidentally close to Harrow School's own Attainment 8 figure, though the two numbers measure entirely different things and should not be confused with one another. Six of Harrow's thirteen named state-funded schools - Park High School, Harrow High School, Hatch End High School, Whitefriars School, Rooks Heath School and Canons High School - sit below Harrow's own borough average of 51.1.
Progress 8 tells a different story from Attainment 8 alone. Harrow High School's 2025 Attainment 8 score of 47.4 places it ninth of thirteen named schools, yet its 2024 Progress 8 score of 0.62 - described by DfE as well above average - matches Nower Hill High School's own 0.62, despite Nower Hill's considerably higher Attainment 8 score of 59. A school's Attainment 8 ranking and its Progress 8 ranking measure different things: Attainment 8 describes the grades pupils leave with, Progress 8 describes how far they travelled to get there from their own starting point. Avanti House School leads on both measures, with a 2024 Progress 8 score of 1.1 from 172 pupils, the highest of any named Harrow school.
Harrow's EBacc entry rate - the percentage of pupils sitting the full combination of English, maths, a science, a language and history or geography - was 66.6% in the 2025 results, well above the England state-funded average of 40.5%. That entry pattern shapes what Harrow families most often ask us to cover, and our subject coverage follows it directly: Maths and English Language and English Literature, the double-weighted Attainment 8 components; Biology, Chemistry and Physics, whether a student is sitting combined or separate science; History and Geography, the EBacc's humanities pillar; and GCSE languages including French and Spanish. Whichever exam board a Harrow student's school uses - AQA, Edexcel, OCR or WJEC/Eduqas - our tutors work from that school's own specification and past papers rather than a generic syllabus. See our full GCSE tuition service for how a programme is structured across a full academic year.
Harrow's independent-school families need a different kind of subject match. North London Collegiate School and The John Lyon School teach English, maths and the sciences as IGCSEs rather than the reformed 9-1 GCSE; Harrow School's own site describes the same subjects as "(I)GCSE," and their absence from DfE's approved-qualifications list confirms they are not the reformed GCSE either. A tutor working from the wrong specification can prepare a student for the wrong exam entirely - Cambridge International and Edexcel International GCSE follow different assessment objectives and coursework requirements from AQA, Edexcel, OCR or WJEC/Eduqas GCSE. Our tutors confirm the exact board and specification a student's own school uses before building a programme, whether that is an IGCSE at one of Harrow's independent schools or a reformed GCSE at one of its state-funded secondaries. Families preparing for entry to Harrow School's Year 9 intake, which uses a non-verbal reasoning assessment alongside English and Maths, can also see our 13+ non-verbal reasoning tutors in Harrow page.
Every Harrow GCSE programme starts with a short diagnostic assessment against the student's own school, exam board and specification, not a generic GCSE checklist, so a tutor can see immediately whether the priority is closing a specific topic gap, building exam technique under timed conditions, or working ahead of a school's own scheme of work. Our tutors hold degrees from leading UK universities and are matched to a student by subject, exam board and year group rather than by availability alone.
Sessions run one-to-one online, with a shared whiteboard that lets 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 one of Harrow's state-funded academies or one of its IGCSE-teaching independent schools. Progress is reviewed against the 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.

Harrow's average Attainment 8 score across its state-funded secondary schools was 51.1 in the 2025 GCSE results, covering the 2024/25 academic year, according to the Department for Education's Compare School and College Performance service. That is close to five points above the England state-funded average of 46.1. Harrow's percentage of pupils achieving grade 5 or above in English and maths was 53.6%, against 45.4% across England's state-funded schools.
Among Harrow's state-funded secondaries, Avanti House School recorded the highest Attainment 8 score in the 2025 results, at 64, with 73.9% of its pupils achieving grade 5 or above in English and maths and an EBacc entry rate of 77.2%. Nower Hill High School followed at 59, with 67.8% reaching grade 5 or above. Both figures come from the Department for Education's published school-level performance data for the 2024/25 academic year; DfE's dataset does not produce a comparable Attainment 8 figure for Harrow's independent schools, for reasons explained below.
Because DfE's Attainment 8 measure excludes International GCSEs, which North London Collegiate School and The John Lyon School use outright for their core subjects, and which Harrow School's own site describes as (I)GCSE for the same subjects, parents are better served by each school's own published results. Harrow School's own 21 August 2025 release reported over 40% of grades at grade 9 and two-thirds at grade 9 or 8; North London Collegiate's release the same day reported 83.4% of all grades at grade 9, 95.9% at grade 9 or 8 and 99.2% at grade 9 to 7 - its best results on those measures since numerical grading began in 2018.
Progress 8 measures how much progress pupils make between key stage 2 and their GCSEs, but the Department for Education states plainly that it is not possible to calculate Progress 8 for academic years 2024/25 and 2025/26, because there is no key stage 2 prior attainment data available for these cohorts after primary tests and assessments were cancelled in academic years 2019/20 and 2020/21 due to COVID-19 disruption. The last year DfE could calculate it was 2024, when Harrow's Progress 8 score was 0.46, well above England's state-funded average of -0.03 the same year.
53.6% of pupils at the end of key stage 4 in Harrow's state-funded secondary schools achieved grade 5 or above in both English and maths in the 2025 GCSE results, according to DfE's Compare School and College Performance data. That compares with 45.4% across England's state-funded schools and 41.8% across all English schools including independents, and it sits inside the national local-authority range, which ran from 24.7% in Knowsley to 69.3% in Kingston upon Thames in 2025.
Among Harrow's named state-funded secondaries, Avanti House School recorded the highest 2024 Progress 8 score, at 1.1, described by DfE as well above average, from 172 pupils included in the measure. Harrow High School and Nower Hill High School both scored 0.62 that year, despite Nower Hill's much higher 2025 Attainment 8 score of 59 against Harrow High's 47.4 - a reminder that a school's Attainment 8 ranking and its Progress 8 ranking do not always move together.
Yes. North London Collegiate School and The John Lyon School teach their core GCSE subjects as IGCSEs outright, and Harrow School's own site uses the same (I)GCSE notation for English, Maths and the Sciences - none of the three appear on DfE's approved GCSE list. Our tutors work from each school's own specification, whether that is Cambridge or Edexcel International GCSE or a standard AQA, Edexcel, OCR or WJEC/Eduqas GCSE at one of Harrow's state-funded schools.
Leading Tuition works with GCSE students at Harrow secondary schools named on this page, state-funded and independent alike, across Maths, English Language and Literature, the sciences, and the humanities and languages that make up the EBacc. Harrow's EBacc entry rate of 66.6% in 2025 was well above the England state-funded average of 40.5%, and our tutors build programmes around the specific subjects, specification and exam board a student is actually taking, whichever Harrow school they attend.
