For international families considering UK boarding schools, the Common Entrance examination is one of the most important parts of the admissions journey and one that often causes the most anxiety. The exam has a reputation that goes ahead of it and the truth is that with the right preparation and the right understanding of what schools are actually looking for, international students consistently perform very well. As former UK boarding school educators we have prepared and assessed many international students through Common Entrance over the years and this guide gives you the honest, practical insight you need to support your child through it in 2026.

What Is the Common Entrance Examination?

The Common Entrance examination is a long established assessment used by many leading UK independent senior schools to evaluate prospective pupils for entry at Year 7, Year 9 or sixth form. It is administered by the Independent Schools Examinations Board, an organisation set up specifically by the independent school sector to provide a common standard against which pupils can be assessed for entry to senior schools.

The exam is most commonly taken at age 13 for entry into Year 9, which is the traditional entry point for many of the most prestigious UK boarding schools. There are also Common Entrance examinations at age 11 for Year 7 entry and a Common Academic Scholarship Examination for students aiming at academic scholarships at senior schools.

Understanding which version of the Common Entrance examination is relevant for your child's intended entry point is the essential first step. Schools will be clear about which assessment they require during the registration and admissions process.

Which UK Boarding Schools Use Common Entrance?

Common Entrance is used by a significant number of leading UK independent senior schools, particularly traditional boarding schools with a strong academic profile. Many of the most well known UK boarding schools either require Common Entrance or accept Common Entrance results as part of their admissions process.

That said, not every UK boarding school uses Common Entrance. Some schools have moved to their own internal entrance assessments. Others use a combination of Common Entrance and their own additional testing. A growing number of schools, particularly those that recruit significant numbers of international students, offer alternative assessment routes designed to accommodate students from different educational backgrounds.

Families should always check the specific admissions requirements of each school they are considering at the earliest possible stage. The assessment route required can affect preparation strategy significantly and the right preparation looks very different for Common Entrance compared to a school's own bespoke entrance test.

Common Entrance Subjects and Format

The Common Entrance examination at 13+ covers a broad range of subjects designed to assess a pupil's academic preparation across the full curriculum.

The core subjects are English, Mathematics and Science. Pupils are assessed in all three of these as a minimum. English typically includes both Language and Literature components, Mathematics is assessed across the standard topics studied in Years 7 and 8 of a UK preparatory school curriculum, and Science covers Biology, Chemistry and Physics at an introductory level.

Beyond the core, pupils typically take a number of additional subjects depending on the requirements of their target school and their own academic interests. Common additional subject choices include History, Geography, Religious Studies, French, Latin, Spanish, German, Greek and others.

The examinations are sat over several days during one of three examination sessions held each year, in November, January and the main session in May or June. Most pupils take the main session in their final year of preparatory school.

How International Students Can Prepare for Common Entrance

International students preparing for Common Entrance face the additional challenge of working towards an assessment designed around the UK preparatory school curriculum which their previous education may not have closely matched. The good news is that with the right preparation strategy, international students consistently perform very well in Common Entrance.

The most effective preparation typically combines a structured tutor led programme covering the specific Common Entrance syllabus with regular practice papers and ongoing assessment to identify and address gaps. Most international families work with a specialist Common Entrance tutor or tutoring company for the year or two before the examination, often supplemented by additional intensive preparation in the final months.

For students whose first language is not English, English language development should be a central focus of preparation. Common Entrance English papers assess sophisticated written expression, analytical reading and grammatical precision that international students sometimes find more demanding than the subject content of other papers. Investment in English language development pays dividends not just in the English paper itself but across every other subject where written communication matters.

Familiarisation with the format and style of UK examinations is also genuinely important. Past papers are widely available and working through them in timed conditions helps students become comfortable with the demands of the examination environment.

When to Start Preparation

The right timeline for Common Entrance preparation depends on the student's current academic level and how closely their existing education aligns with the UK preparatory school curriculum.

For international students whose current school follows a curriculum substantially different from the UK preparatory school programme, beginning structured Common Entrance preparation around 18 to 24 months before the examination is strongly recommended. This allows sufficient time to address curriculum gaps, build subject knowledge to the required level and develop the examination skills the assessment requires.

For students already attending a UK preparatory school or an international school following a closely aligned curriculum, the final year of preparation in the run up to the examination is typically sufficient, supported by the school's own internal preparation programme.

The single most common mistake families make is leaving preparation too late. Students who arrive at Common Entrance under prepared consistently underperform regardless of their underlying ability, and the cost of a poor result can be significant for the admissions outcomes that follow.

Common Entrance and Scholarship Examinations

For students aiming at academic scholarships at UK boarding schools, the Common Academic Scholarship Examination is a separate and more demanding assessment that sits alongside Common Entrance. Most leading UK boarding schools offer academic scholarships and many require or strongly recommend candidates to sit the scholarship examination rather than standard Common Entrance.

The scholarship examination assesses subject knowledge and intellectual ability at a higher level than Common Entrance and is genuinely competitive. Students aiming at academic scholarships should approach this as a serious commitment requiring extensive preparation over an extended period.

Scholarship awards are competitive, not guaranteed, and in many cases reduce annual fees by around ten percent rather than covering a significant proportion of costs. Families should plan their budget on the basis of full fees and treat any scholarship award as a welcome reduction rather than a planning assumption. Following the introduction of VAT on private school fees in January 2025, full boarding fees at UK independent boarding schools now typically range from £40,000 to £60,000 per year.

Visa Requirements and AEGIS Guardianship for International Students

International students attending UK boarding schools require a Child Student Visa to study in the United Kingdom. The school will issue a Confirmation of Acceptance for Studies once a place has been formally offered and accepted following successful Common Entrance results, and this document forms the foundation of the visa application. Families should allow a minimum of three months for visa processing.

UK law requires all international students at UK boarding schools to have a UK based guardian. It is strongly recommended to choose a guardianship organisation with AEGIS accreditation, which is the recognised quality standard for UK boarding school guardianship and ensures the highest standards of safeguarding and professional care.

Supporting Your Child Through Common Entrance

The emotional and practical support that families provide through the Common Entrance preparation year matters as much as the academic preparation itself.

Helping your child maintain a balanced approach to preparation, with structured study time alongside rest, exercise and time for the activities and friendships that sustain their wellbeing, produces better results than relentless cramming. Children who arrive at Common Entrance under pressure and overworked consistently perform below their ability while children who arrive prepared, confident and rested tend to perform at their best.

Talking honestly with your child about what Common Entrance is and is not is also valuable. It is one assessment in a long educational journey. Their performance in it does not define them or determine their long term prospects. The right school for any child can be found regardless of how a single examination goes and the best schools are interested in the whole person, not just their examination scores.

FAQ — Common Entrance Exam for UK Boarding Schools

Is Common Entrance compulsory for entry to all UK boarding schools?

How is Common Entrance graded and what scores do schools require?

Common Entrance results are reported as percentage scores in each subject. The score required for entry varies between schools, with the most selective schools typically expecting scores in the seventy to eighty percent range or higher in core subjects. Schools will be clear about their specific requirements during the admissions process.

What happens if my child does not achieve the required Common Entrance scores?Most schools have an established process for managing this situation, which may involve resit opportunities, additional assessments, or discussions about whether the school is the right fit.
