Why schools screen English at all
International schools teach through English in the great majority of cases, so a school needs a clear picture of how much English an applicant already has. The purpose is practical. The school wants to place the child in the right year group, decide how much language support to put around them, and set a realistic expectation for the first year. A child arriving with almost no English is not usually turned away at primary level, but the school does need to know, because a beginner and a fluent reader need very different plans from the first week.
It helps to separate two things that families often blur together. A cognitive entry test such as CAT4 measures reasoning, and a good school reads a low verbal score in the context of a child who is new to English rather than treating it as low ability. An English proficiency screening is a different instrument. It measures the language itself: listening, speaking, reading and writing. Our overview of admissions test types explains where each sits in the process, and our piece on CAT4 for parents covers the reasoning side in detail.
The tools schools use
There is no single English test that every international school shares, which is one of the reasons families find this stage confusing. Instead schools draw from a handful of established tools and, very often, add their own in house tasks. American curriculum schools commonly use the WIDA screener, a standardised assessment of the four language skills designed for learners of English in an English medium setting. Many other schools use the Oxford Online Placement Test or a Cambridge English assessment, both of which produce a level against a recognised scale. A growing number accept or use the Duolingo English Test for older applicants because it can be sat from home under proctoring.
Alongside or instead of any of these, most schools run their own short assessment. Typically this is a reading passage with comprehension questions, a brief piece of writing, and a conversation with a member of the EAL or admissions team. The conversation matters more than families expect, because it shows the school how the child copes with real spoken English rather than a screen. For older applicants to selective secondary programmes, some schools ask for an IELTS or TOEFL result, the same tests used for university entry, although this is far from universal.
Comparing schools by how they support English learners?
Our compare schools tool shows which schools run structured EAL programmes and at what stages they admit beginners. Useful at the shortlist stage if English support is a priority for your family.
The CEFR scale and what the bands mean
Most of these tools report against the Common European Framework of Reference for Languages, known as the CEFR. The scale runs from A1 and A2 at the beginner end, through B1 and B2 in the middle, to C1 and C2 for advanced and near native users. When a school tells you a child is assessed at B1 in reading and A2 in writing, it is describing where the child sits on that shared scale rather than passing or failing them.
The bands are useful because they translate across tools. A child placed at B1 by the Oxford test and a child placed at a comparable WIDA level are described in a common language that admissions teams understand. For a family, the practical value is being able to ask a straight question: at what CEFR level does this school expect a child to be working independently in class, and how does it support the children who arrive below that level. Schools that run strong EAL support programmes will answer this clearly.
Primary entry: support, not selection
At primary level the honest picture is reassuring. Young children acquire a new language quickly when they are immersed in it, and most international schools admit beginners into the early and lower primary years without an English threshold. The screening at this stage is almost entirely about planning. It tells the school whether the child needs intensive early support, some in class help, or none at all, and it gives the class teacher a starting point.
The exception is a small number of heavily oversubscribed schools that use every input, including English readiness, to choose between many qualified applicants. Even there the language assessment is one factor among several rather than a gate. If your child is joining in the early years and you are anxious about their English, the more useful questions are about the shape and intensity of the school's support, not about whether the child will pass a test. Our guide to choosing an international school sets out how to weigh this against the other factors.
Secondary and sixth form: where thresholds appear
The calculation changes as children get older. A student joining in the final years of secondary faces a demanding curriculum, external examinations, and far less time to learn the language of instruction and the subject content at the same time. For this reason some selective schools do set a working English level for entry into the upper years, particularly for the IB Diploma or A level pathways. The school is not being unkind. It is judging whether a student can realistically succeed in high stakes courses taught and examined in English within the time available.
Where a threshold exists it is usually expressed as a CEFR band or an equivalent test score, and schools vary widely in where they set it and how much flexibility they allow. Some run a bridging or foundation year for capable students whose English is still developing. Others offer accelerated language provision in the first year. If your family is moving mid course, read our mid year transfer playbook and our piece on EAL acceleration programmes, because the language question interacts heavily with timing. The curriculum you are aiming at also matters, so it is worth reviewing the IB pathway and the wider curriculum hub before you commit.
What helpful preparation looks like
As with cognitive entry tests, the most useful preparation is familiarity rather than cramming. If you know which tool the school uses, show your child the format so the screening itself holds no surprises, and make sure they understand that a conversation is part of it. Beyond that, the honest advice is that English proficiency grows through use over months, not through drilling in the week before an assessment. Regular reading at a comfortable level, listening to English audio and video, and everyday conversation build the ability the screening measures.
Attend to the basics on the day. A rested child, sitting the assessment at a good time, in a calm frame of mind, will show their real level rather than a level depressed by nerves. If your child has an identified additional need, request access arrangements in advance and send the documentation with the application so the school can plan. And ask the school directly what happens after the screening: a good school will explain exactly how a child at each level is supported, which tells you far more about the school than the test result itself.
Frequently asked questions
Is there a minimum English level to get a place? At primary level most schools admit beginners and provide support. At secondary and sixth form some selective schools set a working threshold because the academic load leaves little room to learn the language and the curriculum at once.
Which English test will my child sit? It depends on the school. American curriculum schools often use the WIDA screener, others use the Oxford placement test, a Cambridge English assessment or an in house reading and speaking task. Ask the registrar before you apply.
Can my child prepare? Familiarity with the format helps, but the screening measures current ability rather than coached content. Steady reading, listening and conversation over months does more than last minute drilling.
Will a low score be held against my child later? Not usually. It sets the starting point for support. Schools retest and look at progress, so an early low band followed by steady improvement is exactly what they hope to see.
