Overview of Harrow School
Founded in 1572 under a Royal Charter granted by Queen Elizabeth I, Harrow School is one of the most distinguished and recognisable independent boarding schools in the United Kingdom. Situated on a hill overlooking northwest London, Harrow combines centuries of tradition with a modern, forward-thinking approach to education.
The school educates around 850 boys aged 13 to 18, with all pupils boarding on campus. Harrow has long been associated with leadership, public service, and academic excellence, having educated numerous prominent figures including politicians, writers, and leaders across many fields.
Harrow operates a distinctive house system, where each boy belongs to one of the school’s boarding houses. Houses serve as both a pastoral and social hub, fostering a strong sense of belonging and community. House Masters play a central role in mentoring pupils academically and personally throughout their time at the school.
Admission to Harrow is highly competitive. The school receives significantly more applications than places available for its main entry point at Year 9 (age 13). Families considering Harrow often begin planning several years in advance to ensure their child is well prepared for the admissions process.
Entry Points & Age Requirements
Harrow offers two primary entry routes, though the vast majority of boys join the school at Year 9.
Year 9 is the main entry point for Harrow School. Candidates are typically registered while they are in Year 5 or early Year 6 , before sitting the ISEB Common Pre-Test during Year 6.
Successful candidates are then shortlisted and invited to further assessments and interviews in Year 7 or Year 8 .
Approximately 160–170 places are available each year for Year 9 entry, making this route highly competitive.
A smaller number of boys join Harrow for the Sixth Form (Year 12) . These places are limited and typically offered to students with exceptional GCSE results and strong academic references .
Candidates applying at this stage must demonstrate both academic excellence and the potential to contribute to Harrow’s wider co-curricular life.
Important: Registration for Year 9 entry should ideally take place by June of Year 5 or early Year 6. Late registrations may be considered but can reduce the likelihood of progressing through the admissions process.
Registration & Deadlines
The Harrow admissions process spans several years and is designed to assess a boy’s academic ability, character, and potential to thrive within the school’s challenging environment.
Families begin by completing a registration form and paying the school’s registration fee. Once registered, candidates are invited to sit the ISEB Common Pre-Test, a computer-based adaptive assessment taken in the autumn term of Year 6.
Performance in this test helps determine whether a candidate progresses to later stages, which may include interviews, written assessments, and school reports.
Because of the selective nature of Harrow admissions, many families begin preparing their sons academically during Years 4 and 5, ensuring strong foundations in reasoning, mathematics, and written English.

The Assessment Process
Harrow’s admissions process is designed to identify boys who will thrive in a rigorous academic environment while contributing positively to the school’s culture and community.
Stage 1: The ISEB Common Pre-Test

Stage 2: Academic Shortlisting

Shortlisted candidates progress to the next stage of the admissions process.
