What changes, and what does not
The structural change is that one teacher in one room becomes several teachers in several rooms, on a timetable the child is responsible for following. The Department for Education's curriculum and assessment review, reporting in November 2025, named exactly that — adjusting to a larger school and multiple teachers — among the pressures that compound at this point, and added a second that parents rarely hear about: the strongest teachers tend to be deployed towards examination years rather than Key Stage 3.
Three further changes are worth stating precisely, because the common assumptions about them are wrong in one case and absent in the others.
- Class size falls. On the January 2026 census the average state-funded primary class held 26.1 pupils, the average Key Stage 2 class 27.6, and the average state secondary class 22.6. The teaching group gets smaller; the school and the year group get much larger. A child moving from a one-form-entry primary may go from a cohort of thirty to one of two hundred.
- The journey usually becomes the child's own. Free home-to-school transport is owed, under the Education Act 1996, where the nearest suitable school is more than two miles away for a child under eight and more than three miles for a child of eight or over. Extended rights apply to lower-income households, including, for children of eleven to sixteen, any of the three nearest suitable schools between two and six miles away. The practical effect of the three-mile line is that a great many eleven-year-olds acquire an unaccompanied daily journey for the first time.
- Uniform requirements are now capped. Section 35 of the Children's Wellbeing and Schools Act 2026 came into force on 1 September 2026 and limits branded items: no more than three for a primary pupil in a school year, and no more than three for a secondary pupil, or four where one of them is a tie. An item counts as branded not only if it carries the school's name or logo but if its colour, design or fabric means it is only available from particular suppliers — which is the limb that catches most secondary uniforms. Middle schools apply whichever cap matches the phase they are deemed to belong to.
Homework is the one area where there is simply nothing to cite. England has no statutory guidance and no departmental recommendation on how much should be set; the position, stated by the department in 2018, is that head teachers decide, that schools are not obliged to set homework at all, and that it is for each school to decide what follows if it is not done. Any figure for expected hours at Key Stage 3 is somebody's house rule, not a national standard.
The dip, and what it actually is
A fall in measured progress after transfer has been observed for roughly four decades, and it is not an artefact of the English system: a survey for the qualifications regulator in 2006 found transfer-related dips in Germany, Ireland, Italy, Scotland, Spain, Tasmania and England. Inspectors reported in 2015, in a report titled Key stage 3: the wasted years?, that transition was too often poorly managed, that progress stalled on arrival particularly in English and mathematics, that teachers were not consistently building on what pupils already knew, and that one inspection report in five identified Key Stage 3 as an area for improvement. The 2025 curriculum review found a substantial drop in engagement at this point, worse for disadvantaged pupils.
So the phenomenon is well attested. The size of it is not, and this is where almost everything written on the subject goes wrong.
The figure in universal circulation — that two in five pupils fail to make expected progress in the year after transfer — comes from a study published in 1999, and reaches most writing on the subject second-hand through a government document of 2008. A companion claim, that around 30 per cent make no progress in mathematics and around half none in English and science, appears in that same 2008 document without an attributable author. No current national statistic measures the dip at all. The 2025 review, which affirms the engagement drop, does not quantify it and does not use the phrase.
The Education Endowment Foundation, which is ordinarily the place to look for an effect size, has no transition strand in its toolkit and attaches no evidence rating to any transition claim. Its own description of the literature is that it is varied and draws heavily on case studies, with slippage in literacy and numeracy the best-evidenced effect. On remedies it is blunter still: there is little evidence that interventions aimed specifically at the dip work. Its own randomised trial of a four-week summer school for pupils moving into Year 7 produced indicative gains of about three months in reading and writing that were not statistically significant, on a trial the evaluation itself judged insecure because too few pupils were recruited.
The honest position, then: more than a commonplace, less than a measured quantity, and with no well-evidenced fix.
Who finds it hard
The best British survey of adjustment remains a study of nearly three thousand children published in 2008 for the then Department for Children, Schools and Families, and its headline findings are considerably more cheerful than the genre suggests. Eighty-four per cent of children felt prepared on entering secondary school. A term in, 73 per cent described themselves as happy and 16 per cent as excited, against 3 per cent worried or nervous. Sixty-one per cent said their new school had given them a lot of help settling in.
The same study is where the real finding sits, and it is about distribution rather than average.
- Socio-economic background. Of children from the lowest socio-economic group, 72 per cent did not find it easy to adjust to new routines, against 50 per cent of those from the highest. On settling in generally, 58 per cent against 39 per cent.
- Special educational needs. Thirty-seven per cent of children with identified needs were reported as bullied, against 25 per cent of those without.
- Bullying as the hinge. Around three children in ten had some or many experiences of bullying. Among those whose parents reported it, 63 per cent did not go on to widen their friendships, 72 per cent did not settle well and 66 per cent did not adjust easily to routines. Of everything measured, this is the variable that travels with the others.
Which reframes the question usefully. The thing to ask a prospective secondary school is not whether most children settle — most do — but what happens to the ones who do not, and what the school does about bullying in practice rather than in policy.
One finding in the same study points the other way and is worth keeping: secondary teachers may underestimate what arriving pupils can already do. The authors' recommendation was for more attention to academic continuity, not less.
Setting, and what is known about it
Setting or streaming by ability, which many secondary schools introduce at or soon after entry, has an unusually clear evidence verdict and it is not the one most parents expect. The Education Endowment Foundation's assessment, drawing on 58 studies, gives an average impact of zero additional months' progress, on evidence it rates as very limited.
The distribution again matters more than the average. The effect is slightly positive for high attainers and slightly negative for low attainers, and grouping may also damage the attitudes and engagement of lower-attaining pupils over the longer term. A child placed in a bottom set is, on the best available synthesis, not being helped by the arrangement.
Four systems, not one
Transfer is one of the points where the four education systems diverge most, and British generalisations fail quickly.
- England and Wales. Year 6 to Year 7, at eleven. Because the cohort runs from 1 September to 31 August, the intake spans a child who has just turned eleven to one almost twelve — close to a year of development inside one year group. Wales uses the same structure, and from the 2027/28 intake it acquires something new: a statutory co-ordinated admission scheme, with a common application form, an October application deadline and a prescribed Secondary Offer Day, under regulations made in 2024. Families applying in the autumn of 2026 are the first cohort under it.
- Scotland. P7 to S1, starting in August. The cohort runs from March to February, so the S1 intake is around six months older on average than the Year 7 intake south of the border. The vocabulary differs too: the catchment school is the zoned or local designated school, there is no national offer day, and asking for a different school is a placing request rather than a preference.
- Northern Ireland. P7 to Year 8, and the umbrella term is post-primary rather than secondary — in Northern Ireland "secondary" usually means a post-primary school that is not a grammar. Academic selection continues, organised privately, with the education department having no role in it. The two former tests no longer exist. The assessments run by AQE and by the transfer consortium ended with the November and December 2022 sittings, and from November 2023 a single common assessment run by the Schools' Entrance Assessment Group replaced both. The department's current advice to parents names only that one. This matters for anyone checking: an older departmental page still describes two separate tests, and has not been updated on the point.
- Three-tier areas in England. In the authorities that still run middle schools there is no transfer at eleven at all. Children move at roughly nine and again at roughly twelve or thirteen. The number of such schools is not published — the department folds middle schools into primary and secondary according to how each is legally deemed — so no current national figure exists; there were around 120 across seventeen areas in the late 2010s and fewer now. Central Bedfordshire is a confirmed example for 2027 entry. The national application calendar applies unchanged, simply to a different year group.
Whether a middle school counts as primary or secondary is a legal classification rather than a description of what it teaches: regulations made in 2002 deem a school secondary where its age range sits mostly above eleven and primary where it sits mostly below.
What schools must do, and what they only usually do
Two duties are statutory and both are worth knowing, because they are the things that can actually be asked about.
Records must be passed on. Under regulations of 2005, the old school must transfer a pupil's common transfer file and educational record to the new one within fifteen school days of the child ceasing to be registered. That is the legal hook behind the vague assurance that information is shared between schools.
For a child with an education, health and care plan, the secondary school is named before anyone else gets an offer. Regulations of 2014 require the local authority to review and where necessary amend the plan, naming the school or type of school the child will attend, by 15 February in the calendar year of transfer — so for a September 2027 move, by 15 February 2027, a fortnight before mainstream offers are issued. The place comes through the plan rather than through the application round, which is a sequencing difference worth understanding rather than discovering.
Against those, a great deal of what is assumed to be required is not. There is no statutory duty in England to run induction days, taster days or a summer school. Those are professional practice, near-universal and valuable, but a school that does little is not breaking a rule. Nor does any current national catch-up funding exist for this specific purpose: the summer schools programme was a one-off pandemic-recovery scheme in 2021, and the Year 7 literacy and numeracy catch-up premium was discontinued, with its last payments made in early 2020. Pupil premium funding may be spent on transition work, including on pupils from other schools attending a summer school, but there is no transition element within it.
What practice actually looks like, from the 2008 survey: 82 per cent of children attended an open day, 81 per cent made extra visits, and 63 per cent had a Year 7 teacher visit their primary school. Only 17 per cent were assigned an older mentor — the one common measure that was rare, and the one the researchers recommended extending.
What children themselves said helped, in order: help finding their way around, relaxed rules in the first few weeks, making friends, the visits, and the induction booklet. The second of those is the least obvious and the most telling — time to learn the routines before being held to them.
What changes next
A revised national curriculum, arising from the 2025 review, is due to be published by spring 2027 for first teaching from September 2028. Two assessment changes are intended alongside it and both land just after transfer: a statutory Year 8 reading test covering fluency and comprehension, and an expectation that schools assess progress in writing and mathematics in Year 8. Neither has an announced start date. A teacher development programme aimed at Year 7 pupils who arrived below expectations in mathematics is being expanded from the 2026/27 academic year.
A revised School Admissions Code was expected during 2026 and had not been published by early November. Anyone relying on the application and appeal rules should check the version in force rather than any second-hand account of it.
