Do UK boarding schools require IELTS or a Cambridge certificate?

No. They assess English themselves through their own papers, the ISEB Pre-Tests, UKiset and interviews. A Cambridge B2 First or C1 Advanced certificate is useful evidence, and it never expires, but it is not a requirement. IELTS is not recommended under 16.

Can a child with little English get a place?

At the most selective schools, rarely: Concord states it cannot teach beginners and requires intermediate English on arrival, and Wellington wants proficient speakers and writers. Schools with strong EAL departments take lower levels at 11+ and 13+. For 16+ entry, B2 is the realistic minimum because the courses assume it.

Is a UKiset report enough?

It is usually the first step, not the decision. Schools use it to compare international applicants, then run their own papers and interviews. Wellington makes it optional at 13+ because the ISEB Pre-Test already covers English and verbal reasoning, and mandatory at 16+ for non-native speakers.

My child is strong in maths and science but weaker in English. Does that help?

Schools look at the whole profile, and a strong maths or science paper counts. English still has to clear the school's threshold, because every subject is taught and examined in English. Ask what EAL support the school provides and for how long.

Should we take B2 First for Schools before applying?

It is not required, but it is good evidence at 13+ and 16+, it never expires, and preparing for it raises exactly the reading and writing the schools test. If the timetable allows, it is a sensible step a year before the application.

How much preparation is realistic?

For 11+ or 13+ entry with solid school English, about 10 hours on the papers and the interview. For 16+ entry with UKiset, a term of about 20 hours, because sixth-form reading and writing take time. A child told to arrive with intermediate English needs a longer block before the tests. Our boarding school course page has the detail.

What English level do UK boarding schools require at 11+, 13+ and 16+?

By Michael Thompson - Head of Teaching Excellence; 15 years as an IB Coordinator

Published 17 October 20268 min read

In short: Enough to be taught in English from the first day, assessed by the school itself. At 11+ and 13+ most schools use their own papers or the ISEB Common Pre-Tests, which include English comprehension and grammar; at 16+ many add UKiset for non-native speakers and expect sixth-form reading and writing. Few schools publish a number; where secondary sources quote one it is around IELTS 5 to 5.5, CEFR B1+ to B2, with EAL support after arrival. The UK Child Student visa has no English test.

Families in Germany, Austria and Switzerland often assume a British boarding school wants an IELTS certificate. It does not. Schools assess English themselves, as part of the same process that tests maths and reasoning and ends in an interview, and they say surprisingly little in public about the level they expect. Wellington puts it as 'proficient, if not fluent'; Concord College says 'intermediate' and that it cannot teach beginners.

This guide sets out what is actually tested at each entry point, what the words mean in practice, what support exists after arrival, how the visa fits, and a realistic timeline from a German-speaking school. It draws on the admissions pages of Wellington, Oundle and Concord, ISEB, UKiset and GOV.UK as read on 17 October 2026. Policies differ by school and change by year, so confirm with the school or your agency.

How schools assess English

Their own entrance papers: an English paper with comprehension and composition, alongside maths and often science or a language, sat at the school or remotely.
The ISEB Common Pre-Tests at 11+ and 13+: online, adaptive, with maths, English (reading comprehension and grammar), verbal and non-verbal reasoning, usually taken in Year 6 or 7 and available abroad at international schools and approved centres such as the British Council.
UKiset for international applicants, especially at 16+: vocabulary, maths and non-verbal reasoning plus an English level from Cambridge Linguaskill, reported to up to five schools. Gabbitas says more than 250 schools use it.
An interview, typically 30 minutes online with the Head or an admissions tutor, sometimes a group discussion.
References and school reports from the current school, which also comment on English.

IELTS and Cambridge certificates are not required. They can be useful evidence, and IELTS is not recommended under 16 in any case.

By entry point

Entry	What is tested	English expected	Examples
11+ (Year 7)	School's own papers in English, maths and often a cognitive test; or the ISEB Common Pre-Test	A child who can read a short unseen passage and write a few paragraphs in English; EAL support is common at this age	Oundle: January tests in maths, English and a cognitive ability test
13+ (Year 9)	ISEB Common Pre-Test in Year 6 or 7, then the school's 13+ papers; UKiset optional at some schools	Reading comprehension and grammar at the Pre-Test level; writing in paragraphs under time	Wellington: all 13+ candidates sit English and verbal reasoning in the Pre-Test, so UKiset is optional; Oundle 13+: maths, English, science and usually a modern language
16+ (Sixth form)	School's own written assessments, often in the November a year before entry; UKiset required by some schools for non-native speakers; interview	Sixth-form reading and essay writing; enough English to study A-levels or the IB from the first week	Wellington: UKiset mandatory for 16+ non-native speakers; Oundle: November assessment weekend, register by 1 October; Concord: intermediate English on arrival, no beginners

What 'intermediate' means in practice

Where schools or secondary sources attach a number to the expectation, it sits around IELTS 5 to 5.5, which is CEFR B1+ to B2. In the classroom that means following a lesson delivered at normal speed, reading a textbook chapter with a dictionary, writing a structured paragraph with mostly accurate grammar, and asking a question without rehearsing it first. Concord's 'intermediate' is the same idea.

At 16+ the bar is effectively higher than the number suggests, because A-level and IB courses assume reading of non-fiction at length, essays of several pages, and the vocabulary of each subject. A student at B2 can start; a student at B1 will spend the first term catching up and may be steered towards subjects with less writing.

Support after arrival: EAL

Most schools run English as an Additional Language (EAL) lessons for pupils who need them. Wellington says EAL 'can be given to those who require it'; Concord provides EAL tuition once the intermediate threshold is met. Some schools charge for it: Luckley House, for example, charges EAL lessons at its normal hourly rate divided by the size of the group. Ask each school whether EAL is included, timetabled against other subjects, and for how long it is available, because support that stops after a year is a different offer from support through to the sixth form.

The interview

Expect an online conversation of about 30 minutes with the Head or a senior member of staff, in English, about school, interests, reading and why this school. Queen's College Taunton describes exactly this format for international applicants. Some schools use a group discussion instead of or alongside the interview. Schools are not testing accent; they are listening for whether the child can hold a conversation, think aloud and ask a question back. Practice helps more than preparation of answers.

The visa

The UK Child Student visa, for ages 4 to 17 at an independent school, has no English language requirement: the Immigration Rules for it ask for an unconditional offer, suitable accommodation, funds and parental consent. A 16- or 17-year-old on a course at RQF level 3 or above may apply as a Child Student or as a Student. The visa fee is £558 plus the immigration health surcharge. Nothing in the visa process asks for IELTS or a Cambridge certificate; the English assessment belongs to the school.

A timeline from a German-speaking school

18 months before entry: agree the school list with your agency and ask each school which tests it uses, whether UKiset is required, and when assessments take place.
12 to 15 months before: register. Oundle's 16+ registration closes on 1 October for the November assessment; ISEB Pre-Tests run from September to late May.
Autumn before entry: sit UKiset if required, within twelve months of entry since results are valid for one year; start English work on the papers and the interview.
November to January: 16+ assessments in November, 11+ tests in January; interviews around the same time.
Spring: offers, often conditional on school reports and, for 16+, on current-school grades.
Summer before entry: a block of English on sixth-form reading and essay writing, or a summer course, so the first term is not spent catching up.
