GCSE Maths Tutors Wimbledon: Who DfE's Results Cover

The Department for Education's summer 2026 GCSE Maths table for Wimbledon is a school-by-school count of grades that covers seven of the nine schools in its file with an SW19 or SW20 address: 1,271 of the 1,532 pupils who finished Key Stage 4 there. King's College School and Wimbledon High School have no Mathematics row in the provisional file, and the six larger covered schools account for 1,240 GCSE Maths entries.

Which schools does Wimbledon's GCSE Maths table actually cover?

Wimbledon is a town inside the London Borough of Merton, and DfE publishes results school by school rather than by town. This page counts a school as Wimbledon's when its address on the Get Information about Schools register (GIAS) carries an SW19 or SW20 postcode and the school appears in DfE's 2025/26 file. Tested against every school in that file for Merton and six nearby boroughs (Wandsworth, Kingston upon Thames, Sutton, Lambeth, Croydon and Richmond upon Thames), the rule picks out nine of 159 schools, all of them in Merton's part of the file.

The register's all-establishments extract of 17 October 2026 agrees on the postcode rule. It lists 14 open establishments with those postcodes and an age range reaching 16, and five are not in DfE's file at all: the Norwegian School in London, Linden Lodge School, TCES National Online School, RR6 and Wimbledon School of Art. A constituency rule would give a different set. The register files Blossom House School in Merton (postcode KT3 6JJ, 15 entries) under the Wimbledon constituency, together with three Kingston upon Thames schools in New Malden. Those three are Coombe Boys' School (174 entries), Richard Challoner School (160) and The Holy Cross School (150), all with KT3 postcodes. This page keeps to the postcode rule, as our Wimbledon A-level Maths page does, and gives no grade or share for those four schools.

Postcode, sex and admissions policy are GIAS's own fields as recorded in October 2026. Pupils at the end of Key Stage 4 is DfE's own count for each school, and entries are DfE's Total exam entries row for GCSE (9-1) Mathematics.

Seven of the nine schools carry a Mathematics row, covering 1,271 of the 1,532 pupils at the end of Key Stage 4, or 83.0%. King's College School (158 pupils) and Wimbledon High School GDST (103) are both in DfE's file, with 14 and 24 subjects respectively, but neither has a Mathematics row, so 261 pupils (17.0%) sit outside the table. DfE's file gives no reason and we offer none.

Seven more schools sit in Merton's file but outside the SW19 and SW20 line, so no grade or share is given for them here: Harris Academy Merton (222 entries), Harris Academy Morden (165), St Mark's Church of England Academy (144), Jus'T'Learn (27), Melrose School (25), Blossom House School (15) and RISE Education (1).

The grade table below compares only schools with at least 100 entries. That removes one of the seven covered schools, Hall School Wimbledon, with 29 entries and 30 pupils, because a single pupil moves a share there by 3.4 points. A floor of 10 would have removed none of the seven, and any floor between 30 and 166 gives the same six. RISE Education shows why a small total is not a small school: its grade breakdown is withheld, as DfE does for a cohort of 5 or fewer, and it has 1 maths entry against 11 pupils at the end of Key Stage 4.

A child at a school with no row has no DfE grade count to start from, so our expert GCSE maths tutors in Wimbledon begin with the child's own mock papers, tier and exam board.

What did the six larger schools' GCSE Maths entries look like in summer 2026?

The table gives DfE's count of entries at each grade from 9 to 1, with U and X as DfE's labels for entries without a numerical grade. A grade with no row in DfE's file is a count of zero: at every school the grades present add up exactly to DfE's own total. Summer 2026 grades were announced on 20 August 2026.

Entries match pupils almost exactly: the widest gap of the six is at Wimbledon College, with 194 entries against 196 pupils at the end of Key Stage 4. Each row therefore describes close to a whole year group rather than a chosen few, and the six together hold 1,240 entries from 1,241 pupils.

These are raw counts of grades. DfE publishes no Progress 8 for 2024/25 or 2025/26, because those pupils had no Key Stage 2 assessments, so nothing here adjusts for the intake a school started with. The 2025/26 data are provisional, the next release is due in February 2027, and a later edition may differ. The release is on the DfE statistics site.

Foundation tier papers award grades 1 to 5 under Ofqual's rules for GCSE Mathematics, a ceiling our GCSE maths subject page sets out beside the Higher tier. Across the six schools 230 of the 1,240 entries sit at grades 3, 2 or 1 or carry a U or X, and our guide to the grade 3 resit rule explains what that means for study after Year 11.

For a pupil at any of these schools, our tutors work on the distance between the child's current grade and the next grade up, because a school's row describes a year group and says nothing about one child.

Is the 2024/25 table the same table as the 2025/26 one?

No. DfE's 2024/25 file, at its latest version, has the same nine schools, but its coverage differs. Eight of them had a "Maths (General)" row in the GCSE (9-1) data, the label DfE used where 2025/26 says "Mathematics", and 1,348 of the 1,504 pupils at the end of Key Stage 4 (89.6%) sat at a school with one. In 2025/26 the figure is 1,271 of 1,532 (83.0%). We treat the two labels as one subject because entries track the Key Stage 4 cohort closely at every covered school: within four pupils in 2024/25 and within two in 2025/26.

Wimbledon High School GDST had 102 entries in DfE's 2024/25 file and has no GCSE Maths row in the provisional 2025/26 file. That is all the two files show. They do not say why, we offer no reason, and a later edition may differ. King's College School has no Mathematics row in either edition, with 156 pupils at the end of Key Stage 4 in 2024/25 and 158 in 2025/26.

An area figure for Wimbledon therefore compares different groups of schools from one edition to the next. Between the two files the Key Stage 4 cohort at these nine schools moved from 1,504 to 1,532, and the share of it with a Maths row from 89.6% to 83.0%: a change in who is in the table and not in how any school did. The 2024/25 file has been revised since it first appeared and the 2025/26 file is provisional, but the cohort and entry totals used here are the same in all three published versions of the 2024/25 edition.

Matching a school across editions needs care. Ursuline High School Wimbledon sits under URN 102683 in the 2024/25 file and URN 151350 in 2025/26, after its conversion to an academy, so the two editions are joined on DfE's establishment code (3155400) and never on URN. Our Wimbledon A-level Maths page covers that conversion.

For a family comparing schools across the two editions, the steadier starting point, and the one our tutors use, is the pupil's own recent results.

Confidence and progress

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.

Amazing tutors!

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.

Great Teaching and Focused Learning

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.

Do the schools' own 2026 figures agree with DfE's provisional table?

Three of the six schools publish a maths-specific 2026 figure that can be set beside DfE's rows. Rutlish reports 69% at grade 5 or above; DfE's rows give 157 of 229, or 68.6%. Wimbledon College reports 91% achieving grade 4 in Maths and 78% at grade 5 or above; DfE's rows give 177 of 194 (91.2%) and 151 of 194 (77.8%). Both agree to rounding.

Ursuline High School Wimbledon does not agree to rounding. Its results table gives GCSE Mathematics as 40% at grades 9 to 7 and 89% at grades 9 to 4. DfE's rows give 86 of 212 (40.6%) and 187 of 212 (88.2%), which round to 41% and 88%: about a point out in each direction. Two of the three schools agree to rounding and one differs by about a point.

DfE itself notes a difference of basis in this area. Its statistics are at pupil level for those at the end of Key Stage 4, whereas the grades JCQ and Ofqual published on results day were at exam-entry level for age 16. The schools' pages do not state which basis they use, so a difference of that kind could account for a small gap, and nothing we have read says that it does at Ursuline.

Ricards Lodge and Raynes Park publish no maths-specific 2026 figure on the pages we read, and Harris Academy Wimbledon's results page refers to its 2025 results, so none of the three is compared. The check covers three schools of six. It shows the provisional table sitting close to what schools say themselves, and no more than that.

Whichever figure is right to a point, it describes a year group; for one child, our tutors start from that child's own mock result and the grade above it.

What should a Wimbledon family use instead of a school table?

A school's row describes a year group. It shows what 236 entries at Ricards Lodge High School or 194 at Wimbledon College achieved, not what one child will. For the 261 pupils at King's College School and Wimbledon High School GDST there is no DfE row at all. Our expert GCSE maths tutors help students across Wimbledon at both Foundation and Higher tier, and a first call covers three things a family already holds: the child's latest school report, a recent mock paper, and the tier and exam board their school enters them for.

Exam boards are not in DfE's file. Rutlish's own page says its Years 10 and 11 follow the AQA linear mathematics syllabus for GCSE; the pages we read for the other five schools do not name a board, so the board is the first thing to confirm with the school or read from the front of a mock paper. Our tutors build each programme around the gaps that school reports, mock results and topic-by-topic diagnostics show, and the other tuition pages for the town are on our Wimbledon locations page.
