Best For
Families seeking an academically strong independent school with broad co-curricular opportunities, visible digital innovation, and a modern approach to wellbeing.
Watch Out For
No published pass mark. The ISEB Pre-Test is adaptive and cohort-relative, so there is no fixed score to aim for. The assessment day tests soft skills that cannot be crammed.

The Complete Admissions Timeline
Every key date, deadline and decision point — with insider intelligence you won't find on the school website. Click any item to reveal verified insider knowledge.
The critical window: The gap between ISEB Pre-Test (Nov/Dec) and EDGE Day (January) is 4–8 weeks — the most important preparation window for Caterham applicants.
Open Mornings & Tours
The 200-acre woodland campus is genuinely worth seeing in person. Open mornings and bespoke tours run throughout the autumn term. Book early.
Registration Deadline
Submission of the application form and £100 registration fee. Ensure your child is also registered with their current school to sit the ISEB Pre-Test.
Stage 1: ISEB Common Pre-Test
Candidates sit this adaptive online test either at their current prep school or at Caterham. It covers English, Maths, Verbal Reasoning, and Non-Verbal Reasoning. The test adapts to your child's ability in real time.
Interviews
Candidates are invited for an informal one-to-one conversation with academic staff. Caterham treats this as a genuine get-to-know-you chat, not a formal assessment.
Stage 2: EDGE Experience Day
Shortlisted candidates attend Caterham's bespoke assessment day. This includes a written Maths paper (30 minutes, non-calculator), a writing task, critical thinking problems, and collaborative problem-solving exercises.
Offer Letters
Offers are emailed to successful families.
Acceptance Deadline
Families must formally confirm their acceptance by the deadline.

Inside the Caterham Assessment Process
Caterham's admissions uses two distinct stages. The ISEB Common Pre-Test filters applicants; the EDGE Experience Day is where offers are actually decided. Most families over-prepare for Stage 1 and under-prepare for Stage 2.
ISEB Pre-Test (Stage 1)
~2.5 hours total · Adaptive online test (ISEB Common Pre-Test)
The ISEB trips up prepared candidates in predictable ways. The adaptive difficulty is the biggest psychological challenge — children who are used to 'getting everything right' can be rattled when questions get harder as they answer correctly. That is the test working correctly.
Maths (Stage 2)
30 mins (Stage 2) · Non-calculator, written paper
The most common trap is running out of time. With 30 minutes and 7–8 substantial problems, there is no time to dwell. If stuck, move on and return.
EDGE Day (Stage 2)
As part of EDGE Day · Creative writing + Critical thinking tasks
The collaborative exercises are observed, not marked for content. Children who dominate the group or try to 'perform' for assessors consistently underperform children who listen, build on others' ideas, and draw quieter peers into the conversation.
Topic Difficulty & Weight
Difficulty (%) and exam weight by topic area
Key takeaway: The ISEB is an adaptive test — there is no fixed pass mark. Your child is being compared to the rest of this year's cohort. Aim to be well above average across all four sections, not to hit a specific number.
Topic Breakdown
Known Exam Traps — ISEB Pre-Test (Stage 1)
Questions get harder as your child answers correctly. Getting stuck is normal and expected — it means the test is working
Unlike paper tests, once an answer is submitted your child cannot return to it. Teach them to commit and move on
Many children have never seen Verbal or Non-Verbal Reasoning before. Dedicated practice is essential
2.5 hours on screen is draining. Practise with online tests, not just paper, to build stamina
The pattern: The ISEB trips up prepared candidates in predictable ways. The adaptive difficulty is the biggest psychological challenge — children who are used to 'getting everything right' can be rattled when questions get harder as they answer correctly. That is the test working correctly.

The Interview & Assessment Day
Caterham's interview runs alongside the ISEB Pre-Test period, not after it. It is a genuine conversation, not an academic test. If your child is natural, enthusiastic, and can talk about their interests, they will do well.
Format
Informal one-to-one conversation
Duration
15–20 minutes
Role in Admissions
Part of a holistic assessment, not a pass/fail gate
Timing: Interview Runs Alongside the ISEB Pre-Test
The interview runs alongside the ISEB Pre-Test period, not after it. This means your child may be interviewed before results are known. The interview is about personality and fit, not academic performance.
What Makes a Strong Impression
The interview may explore what your child is passionate about. Children who can talk in depth about a genuine interest — whether it's coding, cooking, or football — make a stronger impression than those with a rehearsed list of hobbies. Caterham explicitly discourages coached, scripted answers. Natural enthusiasm and curiosity about the school are the strongest signals.
Confirmed Conversation Topics
Compiled from parent reports (2023-2025)
- Your child's hobbies and interests outside school
- What they enjoy reading
- What subjects they like and why
- What they know about Caterham and why they want to come
- Any clubs, sports, or activities they're involved in
The pattern: A genuine get-to-know-you conversation, not a formal test or assessment
Never Asked — Don't Over-Prepare
- Academic questions or mental maths
- Current affairs or politics
- Brain teasers or logic puzzles
- Anything designed to catch them out
What Actually Wins Offers
- 1Genuine enthusiasm and natural conversation
- 2Specific interests they can talk about passionately (not generic answers)
- 3Curiosity and questions about the school
- 4Basic manners and eye contact
“It was really relaxed. They asked about her hobbies and what she likes doing at weekends. She came out smiling.”
“The school made it very clear they don't want coached answers. They want to see the real child.”

Insider Intel: What Other Parents Don't Know
These are the verified insights you will not find on the school website, in Good Schools Guide, or from any single tutoring agency. Each insight is compiled and cross-referenced from 94+ sources including official documents, parent reports, and tutoring industry data.This is the intelligence that gives ClassAce families an edge.
The EDGE Day is the Real Test
The ISEB Pre-Test is a filtering stage. The EDGE Experience Day is where Caterham actually decides who gets offers. Preparation for the Pre-Test alone is not enough. Your child needs to be comfortable with creative, open-ended tasks and group collaboration.
No Guaranteed Prep-to-Senior Entry
Having a child in the Caterham Prep School does NOT guarantee a place in the Senior School. A parent confirmed the school makes this explicitly clear. Prep school families still need to go through the full admissions process.
Wide Catchment = Fragmented Social Life
Caterham draws from a very wide area with bus routes to Sevenoaks, Reigate, and Sutton. A parent reported their child's friendship group was spread across different towns. Consider this if your family relies on local friendships.
Prep School Conversations Start in Year 4
For pupils already in the Caterham Prep, conversations about their suitability for progression begin as early as Year 4. If your child is in the prep and you haven't heard anything positive by mid-Year 5, that may be a signal to explore other options.
ISEB Score is Cohort-Relative
There is no fixed pass mark for the ISEB Pre-Test. Scores are Standardised Age Scores (SAS) where 100 is the national average. Whether your child progresses to the EDGE Day depends on the strength of that year's cohort.
Collaborative Tasks Are Observed, Not Marked
During the EDGE Day, some problem-solving exercises are done in groups. These are deliberately unassessed for marks. However, staff ARE observing how children interact. Dominating the group is counterproductive.
Mandatory Lunch Costs
School lunches are a mandatory extra cost for day pupils, cited at £340 per term on top of tuition fees. Factor this into your budget when comparing with other schools.
Common Mistakes Parents Make
The errors we see most often from families preparing for Caterham School. Avoid these and you're already ahead of the majority of applicants.
Preparing only for the ISEB Pre-Test
The ISEB is just the filtering stage. Many parents focus all their preparation here and neglect the EDGE Day, which is where Caterham actually makes its decisions.
Searching for a fixed pass mark
The ISEB Pre-Test uses Standardised Age Scores. There is no published threshold. The cut-off shifts every year based on the cohort's strength.
Over-coaching for the interview
Caterham explicitly discourages coached, rehearsed answers. Children who sound scripted will underperform children who are simply natural and enthusiastic.
Assuming prep school entry guarantees a senior place
Being in the Caterham Prep does not guarantee progression to the Senior School. Prep school families go through the full admissions process.
Ignoring the collaborative element
The EDGE Day includes group exercises where staff observe interaction skills. Children who try to dominate or show off will not impress.
Caterham vs Competitor Schools
How does Caterham School compare to the schools your child is most likely also applying to? This analysis covers the key factors that actually matter to families.
Important context: Your child is not competing against other Caterham applicants in isolation. Many candidates are simultaneously applying to 3–5 schools on this list. Understanding the overlap helps you plan preparation that covers multiple targets efficiently.

Scholarships & Financial Support
Caterham offers scholarships across five disciplines. Critically, all scholarships can be combined with a means-tested bursary — a fact most families are unaware of. A music scholar from a lower-income family could receive substantial fee reduction.
| Scholarship Type | Value | Available Places | Selection Method | Stackable? |
|---|---|---|---|---|
| Academic Scholarship | Fee remission (varies) | Multiple | Outstanding performance in entrance assessments | Yes |
| Music Scholarship | Fee remission + free tuition | Limited | Audition in January of Year 6 | Yes |
| Sport Scholarship | Fee remission | Limited | Trials and assessment in January of Year 6 | Yes |
| Art Scholarship | Fee remission | Limited | Portfolio + assessment in January of Year 6 | Yes |
| Drama Scholarship | Fee remission | Limited | Workshop + assessment in January of Year 6 | Yes |
| Means-Tested Bursary | Up to 100% of fees | Varies | Financial assessment application | Yes |
* Music, Sport, Art, and Drama scholarship assessments take place in January of Year 6 — register your interest with the admissions team before December. Contact the bursar directly for current fee remission figures.
