Harrow School is located in Harrow on the Hill, London. Founded in 1572 by John Lyon under a Royal Charter granted by Queen Elizabeth I, Harrow is one of the original seven public schools regulated by the Public Schools Act 1868.


Within its broad co-curricular programme, pupils play in ensembles, sing in choirs, perform in plays, and participate in array of sporting activities. The school’s notable alumni include statesmen, writers, social reformers, a Nobel prize-winner and 19 winners of the Victoria Cross.

How to Apply for 13 Plus Entry to Harrow School

Families are strongly advised to visit the school in order to get a feel of its atmosphere and ask questions of interest. Open Mornings take place on Saturdays and include a tour of the school and Boarding House. These events should be attended when the candidate is in Year 4 or above.


In order to be considered for Year 9 entry at Harrow School, boys need to register first. The registration form, available on this page, should be submitted along with a non-refundable registration fee.


The school will ask for a confidential reference from the candidate’s current school at the end of Year 5.

Harrow School Assessments for Year 9 entry

Between October and the end of the Autumn term of Year 6, candidates for Year 9 entry will be invited to sit the ISEB Common Pretest. The Common Pretest measures ability and attainment, and is age-standardised so that no candidate has an advantage over any other based on their age. Whilst in Year 6, the strongest applicants will be invited to meet Harrow’s House Masters.


Also, those candidates who pass the ISEB Common Pretest will be invited back to the school to take the Harrow Test in the Autumn term of Year 7. The Harrow Test comprises two 15-minute interviews, an online predictive test examining skills in English and maths, and classroom-based group activity. The online test is similar to CEM Select, which covers three areas: Verbal, Non-Verbal and Numerical Reasoning.


For those applying for a scholarship and/or a bursary, the admissions process includes completing and submitting a Scholarship and Bursary Application Form, which can be obtained from the admissions team.

How to Prepare for the Harrow School 13+ Assessments

Students who have an experience of dealing with time-pressure and online testing, stand a better chance of doing well on exam day. At Pretest Plus, we specialise in publishing practice tests and courses which help students become familiar with the types of questions they will be asked in the pretest.


Our resources cover Maths, English, Verbal Reasoning and Non-Verbal Reasoning, helping students get used to the layout of actual exam. With detailed explanations for each question and information on statistical averages, our practice tests and courses offer full preparation for those sitting the Harrow pretest.


For the Harrow test, we highly recommend practice tests which focus on developing students’ Verbal, Non-Verbal and Numerical Reasoning skills.


Thoroughly researched, our practice tests help identify students’ strong and weak areas whilst getting them used to answering questions quickly and under time pressure.


As a result, they gain a significant advantage over peers who prefer a less structured approach towards exam preparation.
