The six real decisions a mock grade feeds -- and the one your child's school makes with no rulebook at all.
Book a Free ConsultationA GCSE mock grade is a school's own internal test result, and on its own it decides nothing official. It still feeds six real decisions, from a 25% extra-time request to the tier a pupil is entered for by 21 February 2027 -- and just one of the six, which revision or intervention group a mock places a pupil into, has no outside rule governing it at all.
Already know which of the six decisions below matters most for your child? Our expert GCSE tutors build every programme around a pupil's own school, exam board and tier, not a generic revision plan.

It is not sent to an exam board, it does not reach a university, and it never appears on a certificate. Most of what a family reads after a mock is written as though that settles the question, and it does not, because "do mocks matter" is really six separate, more useful questions, each with its own answer.
A mock grade can be part of the paperwork behind whether a pupil is entered for the Foundation or Higher tier paper. It can be the documented evidence a school submits when applying for extra time or another access arrangement. It can be one input a teacher weighs when setting a predicted grade, and it can be the figure a sixth form checks against its own entry criteria before confirming or restricting an offer. It can decide which intervention or revision group a pupil is placed into for the rest of the year -- the one decision of the six with no outside rulebook at all. And behind all five of those sits a more basic reason schools run a full mock in the first place: a specific piece of exams-regulator guidance that most families never see. Six decisions, six different answers -- and, in one case, no rule to point to at all.
| Decision | What it actually decides | Governing source | Key date |
|---|---|---|---|
| Tier entry | Foundation or Higher tier paper | No board publishes a refusal rule -- only fee-stage dates | Entry deadline 21 Feb 2027 |
| Access arrangements | Evidence for 25% extra time, a reader, a scribe or a word processor | JCQ, Access Arrangements and Reasonable Adjustments | Deadline 21 Mar 2027 |
| Predicted grades | One input into the figure a school submits | UCAS predicted-grades guidance to schools | Set by each school's own process |
| Sixth-form admissions | Whether an offer is confirmed or restricted | School Admissions Code 2021, para 2.6 | Set per sixth form's own published arrangements |
| Intervention/revision grouping | Which group or booster class a pupil is placed into | None found -- the school's own discretion | None published |
| Why mocks happen at all | The exam-condition evidence Ofqual expects a school to hold | Ofqual resilience guidance, updated 4 Mar 2025 | “One set of mocks... should be sufficient” |
A mock grade is often the first real evidence a school has for deciding whether a pupil sits the Foundation or Higher tier paper in the summer -- but the paperwork behind that decision runs on the exam board's calendar, not the mock's. Pearson's entry deadline for the June 2027 GCSE series is 21 February 2027 for UK centres, confirmed independently at OCR for the same series. A tier can still be changed after that date without an extra fee up to Pearson's own amendment stage, 22 April 2027; OCR runs a similarly staged structure. What none of the boards publishes anywhere is a hard cut-off after which a tier change is refused outright -- that boundary, where a school applies one, is the school's own administrative rule, not a requirement stated in writing by any board.
The dates matter because of when a second mock round actually falls. Of 25 schools in a dataset of 54 English secondaries with a dated later mock round, 12 -- including Farnham Heath End, Patcham High School and Tring School -- start that round on 22 February 2027, the Monday after February half term and one day after the GCSE entry deadline above. For those pupils, the second mock cannot change which tier they are entered for; the entry has already closed by the time it runs. It can only change how a pupil spends the weeks before the real exam. Which tier actually suits a pupil, rather than which paperwork window it falls inside, is a separate and more personal question, covered in our guide to Foundation versus Higher tier.
If a mock is being used as evidence for an access arrangement or a tier decision, the weeks around it matter more than usual. Our expert GCSE tutors work subject by subject, at Foundation or Higher tier, to close the specific gaps a school's own assessment has already flagged.
Book a Free Consultation Message us on WhatsAppFor a 25% extra-time application processed from 1 September 2025 onwards, a mock exam is no longer just useful background -- JCQ's own rules make it close to mandatory. Alongside the completed form, a school must supply "a sample of internal school tests/mock exam papers across relevant subjects showing the application of 25% extra time" and "comments and observations from teaching staff in relevant subjects as to why the candidate needs 25% extra time and how they use the 25% extra time awarded." A parent's own view cannot substitute for this: JCQ states directly that "comments from parents cannot be recorded within Part 1 of Form 8 or Part 1 of Form 9." The mock is doing real evidential work here, not sitting in a file unread.
JCQ's current guidance also touches supervised rest breaks, and it is worth reading precisely rather than repeating a shorthand version of it. As a general note, it says supervised rest breaks "may be more effective and appropriate than 25% extra time" for candidates with anxiety or attention difficulties, including many neurodivergent candidates -- a suitability note about who rest breaks might suit, not an instruction to try rest breaks first for every candidate. Separately, and more narrowly, where a candidate's own difficulty is an impairment other than a learning difficulty, JCQ does ask a school's SENCo to "consider the option of supervised rest breaks before making an application for 25% extra time" -- a genuine before, but one scoped to that specific candidate group and to the school's own application process, not to how the exam itself is run on the day.
Two deadlines get run together in most advice on this, and should not be. 31 January is the deadline for modified question papers only. Extra time, a reader, a scribe, a word processor and rest breaks all fall under a separate deadline, 21 March. JCQ has not published a fresh access-arrangements edition for 2026-27 as of this writing -- its current guide remains the edition "valid from 1 September 2025 to 31 August 2026", last updated in March 2026 -- so the 2026-27 dates above are drawn from a board's own key-dates document rather than a JCQ 2026-27 book, because none yet exists.
The eligibility threshold itself is narrower than the shorthand version usually quoted. JCQ does not set a percentile: its own rule is "two below average standardised scores of 84 or less", or one such score alongside a second in the 85-89 range. A mock or another internal test is frequently where that standardised score first gets measured. For what extra time actually changes in the exam room, and how the two deadlines above interact in practice, see our guide to extra time in GCSE mocks.
A predicted grade is not simply copied from a mock result, but a mock is a legitimate input into it. UCAS's own guidance to schools describes a predicted grade as ideally "objective and data-driven", and names what that means in practice: "you could look at past performance, internal assessments, or current student work to inform your predictions." A mock sits inside that middle category, alongside classwork and any other internal test a department runs -- one input among several, weighed by a teacher's professional judgement, not a formula that converts a mock grade straight into a predicted one. How a school actually turns those inputs into a single number is covered in full in our guide to how predicted grades are set; which of a target, mock or predicted grade a family should actually quote on a form is answered separately in target grade, mock grade or predicted grade.
Yes, and this surprises most parents, who assume a school sixth form cannot select on ability at all. The School Admissions Code 2021 allows it directly: "Admission authorities can, however, set academic entry criteria for their sixth forms, which must be the same for both external and internal places." That single sentence is doing more work than it looks -- it is the legal basis for every sixth form that asks for a specific mock, predicted or actual grade before making an offer, and it applies equally to a pupil moving up from the school's own Year 11. It does not hand a sixth form unlimited discretion: four separate rules constrain how that criterion can actually be used, and a 2022 Schools Adjudicator ruling has already tested one school's own arrangements against them. The full set of rules, the redress route open to a family who believes a school got it wrong, and that 2022 case are covered in our guide to whether sixth forms look at mock results.
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.
A predicted grade or a sixth-form offer usually turns on the months right after a mock, not the mock itself. Our expert GCSE tutors work with students right through Year 10 and Year 11, across every exam board, to close the specific gaps a mock has just shown up.
Book a Free Consultation Message us on WhatsAppOf the six decisions on this page, this is the only one with no outside rulebook at all -- and that absence is worth stating plainly rather than filling with a guess. A mock grade routinely decides which booster class, intervention group or extra revision session a pupil is placed into for the rest of the year. No Department for Education guidance, no Ofsted framework document and no JCQ rule governs how a school is supposed to make that decision. A direct search of the government's own website confirms it: searching gov.uk for the phrase "mock exam" on its own returns 91 published documents, but adding "intervention group" to that search returns none, and the same is true searching for "revision group" alongside "mock" -- zero results, from a search tool that plainly works for the underlying terms.
Nor is there a version of the Schools Adjudicator's objection route, which exists for sixth-form admissions, or JCQ's evidence-based process, which exists for access arrangements, for how a school groups pupils by ability after a mock. That does not make the practice arbitrary -- most schools hold their own policy on setting or streaming groups, and asking to see it is a reasonable request -- but it does mean the decision sits entirely inside the school's own discretion, with none of the statutory backstops that apply to the other five decisions on this page. A parent who disagrees with a group their child has been placed in has no external body to appeal to; the only real option is to raise it directly with the school.
Behind all five decisions above sits a more basic one: why a school runs a full mock at all, rather than relying on classwork and shorter tests. The direct answer is a piece of Ofqual guidance most families never see. It "asks that schools and colleges ensure students sit mock exams in exam conditions before their formal exams, and that their papers are retained. One set of mocks for this purpose should be sufficient" -- a single full mock, not a repeated cycle of them, is what the regulator is actually asking for. The same guidance goes out of its way to warn against overdoing it: "Teachers should guard against over-assessment and normally would not need to spend longer on these assessments than they would on their existing assessment arrangements."
It is guidance addressed to schools and colleges, not a law, and it creates no right a parent can enforce directly. It also says something that cuts against what many families are told when a mock paper does not come home: "Students may be given copies, or the original work, where this would support their study." Where a paper genuinely cannot come home, the more usual explanation is not this Ofqual guidance at all but a separate set of rules -- each exam board keeps its own real past papers secure for a defined period after they are sat, for reasons of copyright and future re-use, entirely apart from anything Ofqual has asked schools to do.
Set against the six decisions above, it is worth being equally plain about what a mock grade does not do. It is not sent to an exam board. It does not reach a university through UCAS, which only ever receives a predicted grade, not the mock behind it. It never appears on a certificate, and no official record of it survives past the school that set it.
That gap between what a mock quietly feeds and what it has no bearing on at all is exactly where the confusion families report comes from. Google's own AI-generated summary of this question has given two different answers in the same week: one version told searchers that mock results are used to help sixth forms and colleges decide on conditional offers, and a second version, for a closely related search, said flatly that mock results "do not go to exam boards, colleges, or universities" -- the opposite claim, from the same tool, days apart. Neither statement is wrong exactly; each is describing one end of the same gap. A mock result itself never leaves the school. What a teacher decides to do with it -- entering a tier, writing a prediction, filling in an access-arrangement form -- can travel a very long way.
Further reading: JCQ's own access arrangements guidance is published at jcq.org.uk, and Ofqual's resilience guidance in full at gov.uk.
Whichever of these six decisions turns out to matter, the response happens in the weeks after a mock, not the mock itself. Our expert GCSE tutors build a plan around exactly what a mock has shown up, at Foundation or Higher tier, for any exam board.
Book a Free Consultation Message us on WhatsAppNo. A mock result stays inside the school that set it -- it is never submitted to an exam board, and UCAS only ever receives a predicted grade, not the mock behind it. What a mock can do is shape that predicted grade: UCAS's own guidance to schools describes internal assessments as one legitimate, objective and data-driven input a teacher can draw on when setting a prediction, alongside classwork and other internal tests. The mock itself never travels beyond the classroom; the number a teacher decides to write down afterwards is what actually reaches anyone outside the school.
A mock can be part of the evidence a school uses, but the actual tier-entry paperwork runs on the exam board's own calendar, not the mock's. Pearson's GCSE entry deadline for the June 2027 series is 21 February 2027 for UK centres, and a tier can still be amended without an extra fee up to Pearson's amendment stage, 22 April 2027. No exam board publishes a hard cut-off after which a tier change is refused outright -- if a school applies one, that is its own administrative rule, not something written into any board's published key dates.
For applications processed from 1 September 2025 onwards, JCQ's own rules require it as evidence, not just as background. Alongside the access-arrangement form, a school must supply a sample of internal school tests and mock exam papers across relevant subjects showing the application of 25% extra time, plus written comments from teaching staff on why the extra time is needed. A parent's own comments cannot be used for this -- JCQ states plainly that comments from parents cannot be recorded on the relevant part of the form. The mock is doing genuine evidential work in this decision.
Yes, if it is an ordinary school sixth form: the School Admissions Code 2021 allows a sixth form to set academic entry criteria, which can include a required mock, predicted or actual grade, provided the same criterion applies to a school's own Year 11 leavers and to outside applicants alike. That permission is not unlimited -- four separate rules constrain how a sixth form can actually apply it, and a 2022 Schools Adjudicator case has already tested one school's own arrangements against them. Which grade a specific sixth form actually asks for is a question for that school directly.
The school alone, and entirely at its own discretion. No Department for Education guidance, Ofsted framework document or JCQ rule governs how a mock result should be converted into a booster class, intervention group or extra revision session -- a direct search of gov.uk for the phrase intervention group alongside mock exam returns zero published documents, against 91 for mock exam on its own. Unlike tier entry, access arrangements or sixth-form admissions, there is no equivalent of a Schools Adjudicator objection or a JCQ appeal for this decision. Asking the school directly for its own grouping policy is the only real route available.
Because Ofqual, the exams regulator, effectively asks them to. Its guidance asks that schools and colleges ensure students sit mock exams in exam conditions before their formal exams, and that their papers are retained, adding that one set of mocks for this purpose should be sufficient -- one full mock, not a repeated cycle. The same guidance also warns schools to guard against over-assessment and not to run more testing than their normal assessment arrangements already involve. It is guidance addressed to the school, not a law, so it creates no right a parent can enforce directly.
Often, yes -- Ofqual's own resilience guidance says students may be given copies, or the original work, where this would support their study, which is the opposite of what many families are told. Where a school does say no, the more common real reason is not this guidance at all: each exam board keeps its own genuine past papers secure for a set period after they are sat -- OCR, for instance, states its mock papers must not be uploaded to public websites or shared through file-sharing platforms -- for copyright and future re-use reasons, separate from anything Ofqual has asked schools to do.
Whichever of the six decisions applies to your child's mock, the weeks that follow it are the ones that actually move a grade. Our expert GCSE tutors work at Foundation and Higher tier across every exam board, building each programme around the specific gaps a mock, a school report or a topic-by-topic diagnostic has already flagged.
