The shape of the UK system in 2026
The UK schooling system divides broadly into three streams: state comprehensive (free, residence based), state selective grammar (free, entry tested, available in some local authorities), and independent (fee paying, broadly available across the country). Within independent, a further split runs between day schools and boarding schools, with most of the historically prestigious schools offering both. The system is regulated at country level: England, Scotland, Wales and Northern Ireland have meaningfully different arrangements, and a family returning to Edinburgh navigates a different process from one returning to London.
For most families returning from an international posting, the practical choice is between the state route (catchment by residence, available where you live) and the independent route (selective, fee paying, applied to in advance). Grammar schools are a third route in specific areas (Buckinghamshire, Kent, parts of Birmingham, Trafford, Lincolnshire and a handful of others) and follow their own calendar.
For broader context on coming home, see our companion piece on repatriating with international school kids. For families weighing UK boarding while still abroad, the UK boarding piece sets out that pathway in detail.
The state route
The state school route is residence based. The family applies to the local authority of the area they intend to live in, providing evidence of residence (typically a tenancy or purchase agreement plus utility bills), and the authority allocates a place according to catchment, sibling priority and any oversubscription criteria. The process is generally clean and the allocation is normally communicated within a month of completed documentation.
The complication for returning families is timing. State school allocation depends on actually living at the address, which means returning families often cannot apply until close to the move. For families intending to use the state route, this generally means accepting either an interim school in a less competitive catchment or a small gap between arrival and term start. Families who plan to use a popular catchment school often buy or rent within that catchment specifically, which carries its own market premium.
State schools in mature catchments are often academically strong and pastorally good, particularly in middle income areas of London, Edinburgh, Bristol, Manchester, Cambridge, Oxford and similar university or commuter belts. Returning families are sometimes surprised at the quality of the state option once they have looked at the data rather than the reputation.
The independent and boarding route
The independent route runs on a longer calendar. Most strong day independent schools in London (Westminster, St Paul's, Latymer Upper, City of London) and major boarding schools (Eton, Winchester, Harrow, Marlborough, Wycombe Abbey, Cheltenham, Oundle, Sherborne) have entry tests, interviews and sibling priorities that operate 18 to 24 months ahead. For 11 plus and 13 plus entry, registration is normally required by the autumn before the entry test year. Specifically for the Common Entrance route, the long planning calendar is part of the architecture.
Returning families generally need to engage with the independent process while still abroad. Many UK independent schools accept international candidates well and can arrange entry tests at the family's current international school or at a regional centre. Interviews are increasingly conducted on video alongside an in person visit when the family is back for a holiday. The schools that handle this well will say so on their admissions page; the schools that do not will tell you in the conversation.
Free help with UK school timing
We work with families returning to the UK from every major international posting. If you are 12 to 24 months out and want a sense check on the school calendar in the area you are moving to, the editorial desk is free to parents. Start with the contact form or use the school finder for UK options.
Grammar schools and the 11 plus
Grammar schools are state schools that select by academic test, available in specific local authorities. The 11 plus is sat in September of Year 6 for September entry the following year. Tests typically include verbal reasoning, non verbal reasoning, English and mathematics, and the format varies by authority (CEM, GL Assessment, bespoke local tests).
Returning families intending to use the grammar route need to register the child for the test in the appropriate local authority, which generally requires an intention to reside in the catchment by the test date. Some authorities accept registrations from international candidates; others require a UK address at the point of registration. Preparation is usually structured: many international families work with a UK based tutor for 12 to 18 months ahead of the test, particularly if the child has been on a curriculum that does not cover the specific test content.
For families moving to a non grammar area, the 11 plus is not relevant. For families considering independent schools, the 11 plus equivalents (London Consortium tests, schools' own entrance tests) follow a comparable but separate calendar.
Curriculum bridging from international school
Most international school curricula bridge into the UK system reasonably cleanly. A child on the British curriculum abroad bridges almost seamlessly. A child on IB PYP and MYP bridges into Y7 to Y10 without difficulty and can typically pick up GCSE alongside the cohort. A child on the American curriculum can bridge into Y7 to Y10 with light support; the bridging becomes harder if the child is already in middle Grade 10 or above, because the UK GCSE course is two years and starts in Y10.
The IB Diploma is not normally compatible with mid course transfer to A Level. A child who has started the IB Diploma at age 16 and 17 should ordinarily complete it at a UK school that offers the IB, of which there are many. Our IB and British curriculum hubs set out the bridging detail. UK independent schools that teach both A Level and IB tend to handle returning expat children more flexibly than those teaching only one.
The 18 month application calendar
A working 18 month timeline looks like this. At 18 months out, identify the receiving area and the school options. At 15 months, register at the independent schools the family is targeting and arrange any entry tests. At 12 months, complete entry tests and interviews where required. At nine months, accept or hold places and confirm acceptance deposits. At six months, confirm housing in the catchment area. At three months, complete state school applications where applicable and finalise transport arrangements. At one month, complete the receiving school's pre arrival paperwork and pastoral handover from the leaving school.
This timeline compresses for state route families who can move closer to the date. It expands for boarding families whose preferred schools register two years ahead. Most families on the independent route find 18 months is the minimum workable lead time and 24 months is more comfortable.
Settling well in the first year
The first year back at school carries the social and identity weight described in our repatriation piece. Schools that handle returning expat children well will assign a buddy at arrival, check in at 30 and 60 days, and run a more formal pastoral conversation at six months. Parents should expect the academic side to settle within the first term and the social side to take longer. Friendship patterns in UK schools, particularly in tighter cohorts at independent schools, take a term or two to stabilise for a new arrival.
Many returning families also find that the formal British school environment, with its specific uniform conventions, its competitive sport culture and its more reserved early friendliness, feels different from the international school the child has been used to. The child usually adapts within a term. The parents sometimes take longer.
FAQ
For UK independent schools, 18 to 24 months before the entry date is the working baseline. The strongest day and boarding schools have entry tests, interviews and sibling priorities that operate on long calendars. State school applications run on shorter timelines and are generally based on residence at the time of application.
For grammar schools in selective local authorities, yes. The 11 plus is typically sat in September of Year 6, and arrangements can be made for international candidates. For independent schools, entry tests are usually pre arranged with the school directly and are often sat at the school during a visit.
For university applications IGCSE and GCSE are treated equivalently. The differences matter more at the school level when a child transfers mid course, since not all subjects map exactly between the two. Most UK independent schools accept IGCSE candidates without difficulty and many teach both alongside each other.
The child should normally complete the Diploma at a UK school that offers it. A mid course switch to A Level is technically possible but rarely advisable in the final 18 months of the Diploma. The UK has many IB schools and the receiving school will usually accept a transfer in.
