How to apply to Caterham School
Caterham School is selective. This means that your child will need to take an entrance exam to be eligible for a place.
You must submit your application by early November of Year 6. The same deadline applies for financial support and co-curricular scholarship applications. A registration fee applies.
All applicants are automatically considered for an Academic Scholarship — no separate application is needed for this.
The admissions process involves two exam stages. First, your child will sit the ISEB Common Pre-Test in November of Year 6. Then, in January, they will attend the school's EDGE Experience Day, which includes two further assessments. Unlike many schools, Caterham does not operate a shortlisting process between these stages — all applicants are invited to both.
All applicants are also invited to an informal interview at the school in November.
You will receive the outcome by email in February. If your child is offered a place, you will have until early March to accept.
What will my child be tested on?
The Caterham School 11+ entrance exam takes place across two separate stages. The first is the ISEB Common Pre-Test, taken in November; the second is the school's own EDGE Experience Day, held in January.
Part 1: ISEB Common Pre-Test
The first part of the admissions process is the ISEB Common Pre-Test, an online assessment used by a number of independent schools. Your child can sit this either at Caterham or at their current school, if the school is able to invigilate.
The test consists of multiple-choice questions and is entirely adaptive, meaning the difficulty adjusts based on how your child is performing. It covers four subjects:
Maths
Questions are based on the Year 5 national curriculum, covering a range of topics from arithmetic to multi-step problem-solving. Children in Year 6 may find this section challenging.
English
The English section is split into two parts: reading comprehension, and spelling, punctuation and grammar.
Verbal reasoning
Your child will be tested on their ability to reason and solve problems using written information, including letters, words, symbols and numbers.
Non-verbal reasoning
These questions assess logic, critical thinking and problem-solving using figures and diagrams. Your child will need to analyse and manipulate 2D and 3D shapes.
The ISEB Common Pre-Test takes around two and a half hours to complete. Your child can sit the four subjects together or at separate times. If taking all four subjects on the same day, they will be allowed a short break between each section.
If your child is applying to other senior schools that also use the ISEB Common Pre-Test, they will only need to sit the test once.
Part 2: EDGE Experience Day
In January, all applicants attend Caterham's EDGE Experience Day — a morning or afternoon session that reflects the school's distinctive approach to education. Your child will take two assessed papers:
Maths
A school-set maths assessment.
EDGE paper
The EDGE paper includes a creative writing task, critical thinking problems, and an exercise designed to showcase your child's innovative thinking and problem-solving skills. All assessments are designed to bring out ability and potential, whatever your child has covered in school so far.
The day also includes collaborative problem-solving activities, which are not assessed.
Interview
All applicants are invited to an informal interview at the school in November of Year 6. This is an opportunity for your child to talk about their interests and passions, and for the school to get to know them as an individual.

How can I help my child prepare for the test?
Applying to senior school can feel like a big milestone, but preparation doesn't have to be overwhelming. Here's how you can help your child prepare for test day.
Stay on track with a clear plan
One of the hardest parts of exam preparation is knowing what to focus on, when, and how to make steady progress without it taking over family life.
A clear, structured plan helps your child feel less overwhelmed and more in control. It ensures they build skills in the right order, cover everything they need, and avoid last-minute cramming.
Atom's exam plan makes this easier. Enter your child's target schools and exam dates, and we'll create a personalised weekly plan tailored to the topics they'll be tested on. It shows them what to work on and when, adapts as they improve, and helps them build progress in a calm, manageable way — little and often.
That means less guesswork for you, less stress for them, and a clearer path all the way to exam day.
Build smart exam technique
As your child's knowledge grows, practice tests can help them feel more comfortable with the real exam format.
Atom's mock tests are exact replicas of real entrance exams. They're also unlimited — your child can take the same test repeatedly and see new questions each time. This helps them practise without repeating the same content.
Atom's mock tests are automatically marked. You'll see your child's standardised age score (SAS), where they're doing well, and what they should focus on next. You'll also learn how they compare to other children applying to the same school.
Encourage regular reading
Strong reading skills play a big role in preparation for entrance exams.
Encourage your child to read every day, even for just 10–15 minutes. The key is variety. Mix fiction and non-fiction, different genres, and a range of authors. This helps them become more confident in understanding tone, purpose, and meaning across different texts.
Over time, regular reading will:
- broaden their vocabulary
- improve comprehension and inference
- build confidence in tackling unseen texts
And just as importantly, it can help them enjoy reading — not just see it as exam preparation.

Celebrate progress, not just scores
When you're supporting your child through exam preparation, what really matters is knowing they're moving in the right direction — not just how they scored on a single test.
Atom's progress tracking gives you a clear, simple picture of how your child is doing in each topic and the direction they're moving in. You can see where they're on track, where they might need more practice, and spot progress as it happens.
That makes it easier to give meaningful encouragement, keep motivation steady, and focus on what matters most: consistent improvement, not just one-off results.
Remove the guesswork from ISEB prep.

Worried about how your child will perform in the ISEB Common Pre-Test? The adaptive format can feel unpredictable, but their preparation doesn’t have to.
Atom adapts to your child’s level as they work. We show you exactly what they need to practise and how they’re progressing.
- Follow personalised weekly exam plans that adjust to your child’s performance and show them what to learn next.
- Practise with replica ISEB mock tests that generate new questions every time, so they build real exam skills.
