British boarding schools have a long history of educating students from all over the world, including the United States. For many American families, the idea of a UK boarding school can feel exciting, but also unfamiliar, given the structural differences in entry points, assessments and curricula. The process can be more formalised than US admissions, with earlier deadlines and assessments that can surprise families unfamiliar with the UK system. Understanding these differences early is vital, particularly due to the competitive nature of many of these schools. This guide gives an overview of the system and outlines what American families need to know before applying.
Why American Families Choose UK Boarding Schools
American families are often drawn to UK boarding schools for their strong academic reputation and long-established track record of preparing students for top UK universities. Smaller class sizes allow for greater subject depth, while specialist teaching ensures students are suitably challenged. Many families also value the ability for students to specialise earlier in their favoured subjects, through GCSEs and A-Levels.
Beyond academics, many parents value the emphasis these schools place on character, independence and tradition, with schools often shaped by centuries-old customs, house systems, and historic buildings that form part of daily school life. Boarding fosters responsibility and resilience from a young age, as students learn to manage their time between their studies and wider commitments.
Understanding the UK Boarding School System
The UK boarding school system is typically divided into prep schools, which educate children from ages 7-13, and senior schools, which usually begin at 13 and continue through to 18. At senior school, pupils usually take GCSEs or IGCSEs at age 16 before progressing to A-Levels in the final two years, with these examination results forming the basis of university applications.
While many of the more traditional boarding schools admit pupils at 13+ or 16+, some offer earlier entry at 7+ or 11+, either through attached prep schools or dedicated junior boarding houses. Each set entry point has defined academic expectations, often involving entrance assessments and an interview.
The academic year, generally beginning in September and ending in June, is divided into three terms, and families can choose from a range of boarding arrangements, from full boarding to more flexible weekly options.

How to Apply from the US
1. Choose the Right School
Choosing the right school requires looking beyond league tables or name recognition. Families should consider whether a school is an academic fit, as UK boarding schools often teach at a faster pace and in greater depth than many US curricula. Pastoral care, extracurricular opportunities, and the overall culture of the school are equally important, particularly for children moving overseas. It is also important to assess a school’s experience in supporting international students, as levels of support differ between schools.
It is advisable to apply to a small number of carefully chosen schools rather than focusing on a single option, as competition for places can be unpredictable at each entry point.

2. Register Early
UK boarding schools generally require families to register well in advance of the intended entry year, often 1-3 years in advance. Deadlines can be firm, particularly for popular schools and competitive entry points such as 11+ and 13+. Early registration also allows families time to plan, particularly for children who may need support transitioning to a UK-style curriculum.
3. Prepare for Entrance Exams
Most UK boarding schools require formal entrance assessments. Each entry point has different requirements, each requiring specific preparation.
The most common entry point to UK boarding schools is the 13+. It often involves students taking the ISEB pre-test (which usually takes place in Year 6, when students are 10 or 11). This is a computerised test (testing English, mathematics and reasoning) which acts as an initial screening of students’ academic levels. If a student’s score is deemed acceptable by the school, they are often invited to interview at the school, which involves a 15-minute conversation with a member of staff, and can include an additional writing task. Conditional offers are then made, based on students’ performances in the Year 8 Common Entrance exams which take place when students are 13. These exams test students’ aptitude in additional subjects, including science and history. However, some schools use their own assessments instead, and some allow international students to take the pre-test later.
These examinations often assess skills and knowledge not emphasised in US curricula, particularly in mathematics and English. American students therefore benefit from targeted preparation that bridges the gap between US and UK academic expectations.

4. Attend Interviews and Assessments
Interviews and assessment days play a central role in UK boarding school admissions and may take place either in person or remotely for international families, depending on circumstances. In addition to academic ability, schools are assessing a pupil’s attitude, communication skills and readiness for boarding life. For American students, interviews can feel unfamiliar, as they often contain a wide variety of questions that international students may not have been asked before. Thoughtful preparation helps pupils present themselves confidently while demonstrating their suitability for the school.

Common Mistakes American Families Make
One of the most common mistakes American families make is starting the admissions process too late. This is particularly true for competitive entry points such as the 13+, where planning often begins years in advance. Many families may underestimate the difficulty of UK entrance exams, assuming that strong US school grades alone will be sufficient, not taking into account the difference in academic material. Choosing schools based solely on reputation, rather than academic fit or overall suitability, can limit students’ options. In addition, interviews are often underprepared for, despite playing a significant role in admissions decisions.
How to Maximise Your Child’s Chances of Acceptance
An early academic assessment can maximise your child’s chances of acceptance, as it can identify strengths, gaps in knowledge, and the most appropriate entry point. Targeted, bespoke preparation for entrance exams helps international pupils bridge the gap between their current curriculum and the UK exam system. A school-specific strategy is also helpful, as admissions criteria and assessment styles can vary significantly between schools. Professional guidance offers families expert oversight of the whole process, from early planning and school selection through to assessments and interviews; the process can be difficult when navigating an unfamiliar system from overseas.

Frequently Asked Questions
Can an American child go to boarding school in the UK?
UK boarding schools have a long history of educating students from all over the world, including the United States. American pupils are well represented across both prep and senior schools. Schools are experienced in supporting overseas families with admissions, visas and pastoral care.
What exams do US students need for UK boarding schools?
The exams required depend on the age of entry and the school. Other than the 13+ entry (discussed above), at the entry points, schools may set their own tests in subjects such as English and mathematics, alongside interviews and creative writing tasks.
At what age can Americans start UK boarding school?
American students can enter UK boarding schools at several ages, with the most common entry points at 7+, 11+, 13+, and 16+. Many traditional boarding schools have their main intake at age 13.
Do UK boarding schools accept US curriculum students?
UK boarding schools regularly admit US curriculum students, including those attending American public, private, or international schools. However, because of the differences between UK and US curricula and exams, international students often benefit from targeted preparation to adjust to subject depth, exam technique, and academic expectations.
Is it hard to get into a British boarding school?
Admission can be highly competitive, particularly at highly selective schools and popular entry points such as the 13+. Success depends on academic readiness, performance in assessments and interviews, and suitability for boarding life, rather than examination results alone. With early planning and adequate preparation, many American students gain places at top UK boarding schools each year.
