Oxford High School GDST 13+ Preparation

Oxford High School GDST is a selective independent day school for girls in Oxford, part of the Girls' Day School Trust, that assesses Year 9 (13+) candidates through a day-long Experience Day rather than a single timed exam. Leading Tuition prepares girls for that Experience Day, its taster lessons, entrance assessments and interview with the Head, ahead of the nearest Year 9 deadline: 3 January 2027, for September 2027 entry.

Why "Sit the 13+ Exam" Is the Wrong Picture at Oxford High

Most independent schools that admit at Year 9 set out a single, discrete sitting: turn up on a fixed date, sit two or three timed papers, go home. Oxford High does not run its Year 9 process that way. Once a family has submitted the application form, the school invites the candidate to what it calls an Experience Day, described on its own senior admissions page as an occasion where "she will have the opportunity to experience some taster lessons, sit her entrance assessments and meet her fellow classmates." A separate meeting with the Head is built into the same day, to "explore her interests, aspirations, and what she's most curious or excited about."

That structure changes what preparation actually needs to cover. A candidate is not simply walking into an exam hall for ninety minutes; she is spending a school day being observed across a taster lesson, a formal assessment, and an unscripted conversation with the most senior person in the building. Confidence and stamina across a full day matter as much as accuracy on a maths paper. Outcome letters for Year 9 applicants are sent in March — later than the December letters sent to Year 7 and Year 12 families — which reflects how much of the Year 9 cycle sits downstream of the Experience Day itself rather than a single results morning.

This is also where most published guidance about Oxford High's 13+ entry falls behind. One of the highest-ranking independent guides to Oxford High's 13+ exam, run by a past-paper retailer, still describes the process as two separate routes — a "pre-test" sat in Year 7 and a "standard entry" exam sat in Year 8 — made up of four discrete timed papers: English, Mathematics, a modern language and reasoning, each sixty to ninety minutes long. Whether or not that structure was accurate for an earlier admissions cycle, it is not what Oxford High's own current senior admissions page describes, which instead lists three concurrent Year 9 rounds assessed through the single Experience Day format above. A family preparing against the older two-route, four-paper description is preparing for a process the school does not currently run.

Nor does Oxford High use the ISEB Common Pre-Test, the standardised online assessment that many comparable senior schools rely on for 13+ entry — see our separate guide to what the ISEB Common Pre-Test involves. Oxford High's assessment is written and administered by the school itself as part of the Experience Day, which means ISEB-specific past papers and practice platforms are not a reliable guide to its content or format.

How Our Oxford High 13+ Preparation Programme Works

We build a candidate's preparation around the three strands of the Experience Day rather than treating it as a single exam to drill. Academic work on the entrance assessment itself — reasoning, English comprehension and writing, and mathematics at a level appropriate to Year 9 entry — sits alongside structured practice for the taster lesson and the meeting with the Head, since both are genuinely part of how a candidate is judged, not a formality either side of the real test.

A typical programme starts with a diagnostic session to establish where a candidate's reasoning, writing and mathematics currently stand relative to what Oxford High's entrance assessment expects, then builds a course of weekly sessions from there. Because the school runs three Year 9 rounds rather than one, the right start date depends on which entry year a family is actually targeting — a September 2027 place, with its 3 January 2027 deadline, needs a different run-up to a September 2029 place, where the deadline of 8 November 2026 sits much closer on the calendar despite the later start date. We set the length of a programme against the specific round a family has registered for, rather than a generic countdown to "the 13+ exam."

Taster-lesson and interview preparation is handled separately from academic tutoring, because the two reward different things. A candidate who can solve a maths problem competently in a one-to-one session does not automatically perform the same way in a live classroom being watched by a teacher she has never met, or in an unscripted conversation with the Head about her interests and ambitions. We run mock taster lessons and structured interview practice alongside the academic strand, so a candidate has rehearsed the format of the day itself, not only its content.

Tutors on this programme have direct experience of GDST entrance processes, including Oxford High's own format, and work with candidates individually rather than through a fixed group curriculum, since the gap between where a candidate currently stands and what a specific Experience Day requires varies considerably from one family to the next.

Oxford High Runs Three Year 9 Application Rounds at Once — Which One Applies to You

Unlike a school that opens a single annual window for Year 9 applications, Oxford High currently has three separate Year 9 rounds open concurrently, each targeting a different September start date. All three are published together on the school's own senior admissions page, and the deadlines do not run in the order a family might expect from the entry years alone.

The nearest deadline for most families researching Oxford High today is the September 2027 round, closing Sunday 3 January 2027. That date is an application deadline rather than the date of the Experience Day itself: the school does not publish a single fixed assessment date for Year 9, since candidates are scheduled individually once their application has been received. Families weighing up a later start — for a daughter currently in Year 4 or 5, for example — need to register for the correct round in November 2026 or February 2027 rather than assuming they have until closer to their intended start year, since the earliest-closing deadline in the table above belongs to the latest entry year, not the earliest.

Fees, Bursaries and Scholarships at Oxford High — and What They Mean for Preparation

Oxford High publishes its Senior School fee, covering Years 7 to 11 including Year 9, as £8,148 per term for the 2026/2027 academic year, with non-optional lunch charges of £403 per term on top. Families with three or more daughters attending GDST schools at the same time qualify for a 20% discount on fees for the third and any subsequent daughter, though that discount is not specific to Oxford High — it applies wherever GDST siblings overlap across the trust's schools.

Bursary support is available for Year 9 entry, but Oxford High's own bursary page is specific that this route is open to external candidates only, unlike Year 7 and Year 12 entry, where internal transfers can also apply. The income thresholds that decide eligibility are not an Oxford High policy; they are set centrally by the Girls' Day School Trust, which places Oxford High in its higher "London schools" band rather than its standard band. Under that band, a family with assessable income and resources below £49,500 may be considered for a full bursary, and a family above £107,500 is not eligible at all, with a sliding scale applied in between. A bursary application must be submitted during the main autumn-term application round to be considered — a late application, even for an otherwise eligible family, will not be assessed on the same basis.

Scholarships at Year 9 are offered in five categories: Art & Design or Textiles, Drama, Music, Sport and Academic. The first four each involve a separate, subject-specific application — a portfolio, an audition, or a written submission depending on the category. The Academic Scholarship works differently: Oxford High's own Year 9 Scholarships handbook states that external candidates are assessed for it "based on performance in the entrance assessments and interview," with no separate Academic Scholarship exam or interview at all. In practice, that means a strong performance across the standard Experience Day itself is what earns an Academic Scholarship, rather than a second competitive stage layered on top of it.

If you are researching Year 7 (11+) entry to Oxford High rather than Year 9, the assessment format, deadlines and fee structure differ from everything above — see our separate Oxford High School GDST 11+ preparation page for that entry point.

Which of Our Tutors Cover Oxford High 13+ Entry

Tutors assigned to Oxford High 13+ preparation have direct experience preparing candidates for GDST senior school entrance processes, not only Oxford High's own Experience Day. That matters because GDST schools set their own entrance assessments rather than sharing a single trust-wide exam, so a tutor who understands how one GDST school's process is structured — taster lesson, written assessment, interview — is better placed to prepare a candidate than one whose only experience is with the ISEB Common Pre-Test used elsewhere in the independent sector.

For the academic strand, tutors work across the skills an Experience Day assessment is likely to test: comprehension and extended writing, mathematical reasoning at a Year 9 entry standard, and verbal and non-verbal reasoning. For the taster-lesson and interview strands, preparation focuses on how a candidate presents herself in an unfamiliar classroom and in conversation with a senior member of staff — skills that do not show up on a practice paper but are part of how Oxford High actually assesses candidates across the day. We match a candidate with a tutor based on where the diagnostic session identifies the largest gap, whether that is academic content, written technique, or confidence in an unfamiliar, observed setting, and adjust the balance of the programme as preparation progresses. Our Oxford tutoring coverage includes families based in the city and across Oxfordshire preparing for Oxford High and other local senior schools at both 11+ and 13+.
