How Difficult Is It to Get Into Harrow School?

A practical guide to Harrow School admissions, entrance tests, interviews, academic expectations and what families should know before applying

Getting into Harrow School is highly competitive. The school admits around 160 boys into Year 9 each year, alongside a much smaller number of pupils entering in Year 12. Applicants are assessed not only on academic ability but also on their potential, character, interests, boarding suitability and likely contribution to school life.

For the main Year 9 route, the admissions process begins with the ISEB Common Pre-Test. Boys who pass this stage are invited to take the Harrow Test, which includes an interview, English and Mathematics assessments and a group activity. Successful applicants then have to meet the school's later academic requirements before joining in Year 9.

This makes Harrow a school where preparation needs to begin well before the final entrance assessment.

How competitive is Harrow School?

Harrow is academically selective and has a limited number of places.

The school currently admits around 160 boys into Year 9, normally entering in the September following their 13th birthday. It also admits up to 20 boys into Year 12.

However, the difficulty of admission cannot be reduced to a simple acceptance percentage. Harrow assesses candidates individually, and the strength of the applicant pool can vary from year to year.

The school is looking for boys who are likely to thrive in a boarding environment, contribute positively to school life and demonstrate academic ability or potential. It also considers talents in areas such as sport and the arts, alongside behaviour and leadership potential.

What does the Harrow Year 9 admissions process involve?

Understanding the different stages is essential for families considering an application.

Stage 1 - Registration and school reference

Standard Year 9 applicants should be registered by 30 September of Year 6. Harrow notes that applications made after the end of Year 5 are treated as late applications and compete for fewer places.

The school also requests a confidential reference from the applicant's current school at the beginning of Year 6.

This means a child's academic record and school performance are already part of the admissions picture before the main testing stages.

Stage 2 - ISEB Common Pre-Test

All Year 9 applicants are required to sit the ISEB Common Pre-Test.

The assessment covers:

• Verbal Reasoning

• Non-Verbal Reasoning

• English

• Mathematics

It is an online, age-adaptive assessment and takes approximately two and a half hours. Standard applicants normally sit it between October and the end of November in Year 6.

The age-adaptive nature of the test means that children are not simply being compared according to raw marks.

How difficult is the ISEB test?

The ISEB Common Pre-Test can be demanding because children must work across several different academic and reasoning areas.

A child may be strong in Mathematics but less comfortable with verbal reasoning. Another may have excellent reading skills but need more practice with non-verbal reasoning.

Preparation should therefore be balanced.

Parents can help children develop:

• Reading comprehension

• Vocabulary

• Mental mathematics

• Problem-solving

• Logical thinking

• Pattern recognition

• Speed and accuracy

The objective should be familiarity with the assessment format rather than memorising specific questions.

Stage 3 - The Harrow Test

Passing the ISEB Common Pre-Test does not automatically secure a place.

Successful candidates are invited to take the Harrow Test during the spring term of Year 6.

The Harrow Test consists of:

• A 20-minute interview with a House Master

• Computerised English and Mathematics assessments lasting one hour in total

• A 20-minute classroom-based group activity

This makes Harrow's selection process broader than a traditional written entrance examination.

A child needs to demonstrate academic ability while also being able to communicate and participate effectively.

How important is the Harrow interview?

The interview is an important part of the second-stage assessment.

Parents should help children become comfortable discussing their genuine interests rather than teaching them scripted responses.

Potential areas of conversation include:

• Favourite subjects

• Books

• Sports

• Music

• Hobbies

• School experiences

• Recent achievements

• Things they have learned independently

• Future interests

The child should be able to explain their opinions clearly and respond naturally to follow-up questions.

A rehearsed answer can sound impressive for a few seconds, but genuine curiosity and thoughtful conversation are much more useful preparation.

The group activity can also matter

The Harrow Test includes a classroom-based group activity.

This means children should have experience working with others before the assessment.

Useful experiences can include:

• Team sports

• Drama

• Music groups

• Debates

• School projects

• Clubs

• Collaborative competitions

The goal is not to make the child dominate the group.

A good participant should be able to listen, contribute useful ideas, cooperate and respond appropriately to other people's views.

What does Harrow look for in a candidate?

Harrow's admissions information states that it welcomes boys who are likely to thrive in a boarding environment and make the most of the opportunities available.

The school also looks for candidates who can make a positive contribution both inside and outside the classroom, demonstrate talent or potential, have a good behavioural record and show leadership potential.

This is important because it shows that admission is not based exclusively on examination marks.

A strong candidate should ideally have a combination of academic ability, personality, interests and readiness for boarding.

Does a child need perfect grades?

No.

Harrow is academically selective, but the school specifically refers to academic ability or potential as part of its admissions criteria.

Parents should therefore focus on whether their child is progressing strongly and demonstrating the ability to tackle challenging work.

Strong preparation includes:

• Building excellent reading habits

• Developing mathematical confidence

• Practising reasoning

• Encouraging independent thinking

• Discussing ideas at home

• Developing genuine interests

• Strengthening communication skills

The aim should be sustained development rather than chasing perfect marks in every school test.

When should parents start preparing?

Parents should start thinking about Harrow several years before the child actually enters the school.

This does not mean intensive entrance-exam tutoring from an early age.

Instead, the early years should focus on building the foundations that selective schools value.

A sensible progression is:

Early preparation

Develop reading, mathematics, curiosity and independence.

Year 5

Research Harrow carefully, understand the entry requirements and prepare for registration.

Year 6

Complete registration, school references and the ISEB Common Pre-Test.

Spring of Year 6

If selected, prepare for the Harrow Test, including the interview, English, Mathematics and group activity.

Years 7 and 8

Continue strong academic development and prepare for the examinations required to confirm the place.

Getting an offer is not the end of the process

One particularly important point is that receiving an initial offer does not mean the academic requirements are finished.

Harrow states that Year 9 offers are subject to the applicant subsequently sitting either Common Entrance or the school's Academic Scholarship examinations in Year 8. The precise requirements depend on the applicant's current school and curriculum.

This means families should plan for continued academic preparation after receiving an offer.

The child should not assume that the Year 6 assessment is the final hurdle.

What about Harrow scholarships?

Scholarship entry is even more competitive.

Harrow offers scholarships in areas including:

• Academic study

• Sport

• Music

• Drama

• Art and Design Technology

Scholarships are based on an overall assessment that considers academic ability or potential, character, boarding suitability, the needs of the school and the strength of the candidates applying.

Academic Scholarship candidates face a particularly broad assessment, including English, Mathematics, Analytical Reasoning, Philosophy and Applied Ethics, General Linguistic Skills, Science and additional subjects.

Parents should therefore distinguish ordinary admissions preparation from scholarship preparation.

What about entering Harrow at 16?

Year 12 entry is even more limited.

Harrow admits up to 20 boys into Year 12 each year. Applicants are generally expected to be predicted at least seven or eight GCSE or equivalent passes at grades 7, 8 or 9. Candidates are also assessed in subjects they intend to study in the Sixth Form.

Strong applicants may then be invited to an assessment day involving further tests and interviews.

For international applicants, additional arrangements apply to overseas testing and assessment visits.

Can international students get into Harrow?

Yes. Harrow accepts applications from overseas schools and has specific arrangements for international candidates.

For the ISEB Common Pre-Test, an overseas applicant can normally arrange for their current school to provide a suitable testing environment and supervision. If the school cannot administer the test, Harrow states that a local British Council office or another educational establishment may be used as an alternative venue.

International families should nevertheless begin planning early because overseas applications can involve additional travel and logistical requirements.

How can parents improve their child's chances?

There is no guaranteed formula for gaining admission, but parents can make the application stronger by focusing on the areas Harrow actually assesses.

Build academic strength

Focus on English, Mathematics, reasoning and the child's broader academic development.

Encourage reading

Regular reading helps develop vocabulary, comprehension and the ability to discuss ideas.

Develop independent thinking

Ask children to explain how they reached an answer rather than simply telling them whether they are right.

Build confidence

Encourage children to communicate with adults and participate in group situations.

Develop genuine interests

Sport, music, art, technology, science, reading and other interests can help children develop confidence and contribute to school life.

Prepare for boarding

A child should gradually become more independent and comfortable managing responsibilities away from parents.

Avoid excessive coaching

The biggest mistake can be turning the admissions process into a source of constant pressure.

Too much preparation can result in:

• Anxiety

• Exhaustion

• Loss of motivation

• Reduced enjoyment of learning

• Dependence on rehearsed answers

Harrow is looking for boys who can thrive in its environment, not simply children who can complete practice papers.

Preparation should therefore strengthen the child's genuine abilities rather than replace them.

Is Harrow worth applying to if admission is difficult?

Yes, if the school genuinely suits the child.

The fact that admission is competitive should not automatically discourage a strong candidate.

However, parents should avoid making Harrow the only possible outcome.

A sensible application strategy involves researching several suitable UK boarding schools and comparing their:

• Academic standards

• Entry points

• Boarding arrangements

• Pastoral care

• Sports and activities

• Fees

• International student arrangements

• School culture

The goal is to find a school where the child can thrive, rather than simply obtaining the most prestigious name.

Plan the practical side of moving to the UK

For international families, securing a Harrow place can lead to wider relocation decisions.

Parents may need to consider whether to:

• Continue living overseas while the child boards

• Rent a UK property

• Purchase a family home

• Maintain an existing UK property

• Arrange property management while abroad

These decisions should be planned alongside school fees, travel and other education-related costs.

Fraser Bond support for international Harrow families

Fraser Bond does not provide Harrow admissions consultancy, entrance-exam tutoring, interview coaching, guardianship services or immigration advice.

Its role is focused on the UK property side of an international family's relocation.

For parents who own or rent property in the UK while their child attends Harrow, Fraser Bond can support relevant requirements including property management, inspections, maintenance, repairs, refurbishment and contractor coordination.

This can give overseas families a reliable local point of support for their UK property while they focus on their child's education.

So, how difficult is it to get into Harrow School?

The short answer is very competitive.

Harrow has a limited number of Year 9 places and uses a multi-stage admissions process. Candidates must first complete the ISEB Common Pre-Test and, if successful, progress to the Harrow Test, which includes academic assessments, an interview and group activity. Offers are then subject to further academic requirements before entry.

The best way to approach the process is not to look for shortcuts or guaranteed admission.

Instead, families should start early, understand Harrow's requirements, build strong academic foundations, prepare the child for different assessment formats and ensure that the child is genuinely ready for boarding.

For international families, careful planning should also cover travel, immigration requirements and UK property arrangements.

Harrow is difficult to enter because it is selective and has limited places. However, a well-prepared child with strong academic potential, genuine interests, good communication skills and the right personality for boarding can put forward a much stronger application.
