Inside City of London Boys’ in 2026: A Parent’s 11+ Guide for 2027 Entry
So how do you actually get into CLS?
It is the question I am asked most often, by parents whose sons are in Year 4 or Year 5, at the kitchen table at 9pm on a Tuesday. They have usually spent two hours on Mumsnet and another forty minutes on a tutoring blog, and are no clearer for it.
Two things to know up front. First, CLS preparation does not have to take over your family life. The school deliberately avoids the hothouse feel of some of its peers, and that shows up in admissions. They want articulate, curious, kind boys, not boys whose only skill is sitting an exam. Second, the bursary scheme at CLS is real. The school publicly commits all available bursary funds to means-tested awards, and the cohort genuinely reflects that.
CLS sits in an unusual place among London independents. The location alone — Thames-side, between the Millennium Bridge and the Tate Modern — gives boys a learning environment no other school can match. The Talk! lecture series brings major thinkers into school. London itself is part of the curriculum.
This guide is current as of May 2026, for parents whose sons will sit in late November 2026 for September 2027 entry. By the end you should be calmer than you started.
Inside CLS in 2026
City of London School sits on the banks of the Thames at Queen Victoria Street, with the Millennium Bridge and Tate Modern next door. The setting is unusual for a London independent. So is the ethos. CLS publicly commits all available bursary funds to means-tested awards, and the diversity is something current parents speak about as a real and lived part of school culture.
The school’s framing is “Kind, Aware, and Ready”, and the Towards 2030 strategy keeps returning to those three qualities. The Talk! lecture series brings external speakers into school. CLS holds its own among the top academically selective boys’ schools but without the high-pressure feel some of its peers have.
What parents tell us they love ?
The City of London location, with lectures, museums, and theatre on the doorstep. Genuine commitment to bursary diversity. The Talk! lecture series. Strong creative culture alongside academic depth. The riverside campus between the Millennium Bridge and Tate Modern.
What parents tell us they worry about ?
Multiple sections in one morning — stamina matters. The online assessment format is unfamiliar to boys who only practise on paper. The creative writing piece is short but carefully read. The interview can include moral or ethical questions. A group activity in January is observed alongside the interview.
A note from Reena. Visit. Walk the campus. Watch boys move between lessons. The right school is the one your son will thrive in for seven years, not the one with the most prestigious name on the gates.
The admissions process for September 2027 entry
CLS runs a computerised assessment in late November, a creative writing piece, and then interview and group activity in January for shortlisted boys. There is no fixed pass mark — offers are based on assessment ranking across the cohort. Verified against cityoflondonschool.org.uk in May 2026.

The papers and the assessment in detail
What follows is a parent-friendly map of each stage, with the named techniques we teach.
What follows is a parent-friendly map of each stage, with the named techniques we teach.
No real exam questions appear in this guide. Every example is written by Academic Success in the style of the paper.
Stage 1: Computerised assessments (late November)
Online tests run at CLS via Atom Learning, covering English, Maths, Reasoning, and a Creative Composition / Writing task. The English and Maths sections test Key Stage 2 content with multiple-choice questions, paced fast. The Reasoning section covers verbal and non-verbal reasoning. The Creative Composition asks for a short structured piece on a given stimulus.
For the multiple-choice sections we teach three non-negotiables. Skip-and-Return: if a question takes more than 30 seconds, mark it, move on, return at the end. The Inference Ladder for English comprehension (literal meaning → key word → connotation → writer’s intent). And 4-Step Elimination for multiple-choice maths: read the answers before working, rule out the absurd, estimate, then calculate the precise answer from one or two remaining options.
For the Creative Composition, the STAR Method structures a short story under timed conditions: Setup, Tension, Action, Resolution. And the In the Action Rule for openings — open with a character already doing something interesting, not “It was a sunny morning.”
Worked example, in our voice. Stimulus: “The clock on the platform had stopped at 4:17.” A boy who writes “I looked at the broken clock. It said 4:17. The train was late” has begun in the wrong place. A boy who writes “I had been staring at the clock for so long I had stopped seeing it” is already in the story, already characterised. CLS markers read for that distinction.
Stage 2: Interview and group activity (January)
A 15–20 minute one-to-one interview with senior staff, plus a group activity observed alongside. The interview ranges across reading interests, general knowledge, and sometimes a moral or ethical question. CLS markers reward boys who think aloud rather than perform a rehearsed answer.
For the interview we teach the Out Loud Method: when asked an open question, do not start with the answer. Start with how you are thinking about the question. “I’m not sure, but here is how I would think about it” beats a confident wrong answer every time.
For the group activity, the key skill is contributing without dominating. Listen to others, build on their ideas, offer your own without insisting. CLS markers watch for kindness alongside intelligence.
What CLS is really looking for
The assessment tests reading, writing, maths, reasoning, and verbal communication. That is true, but it is not the whole story. Across the boys we have helped onto the CLS offer list, four qualities show up repeatedly.
- Stamina across a long assessment morning. The computerised assessment runs across multiple sections in sequence. Boys who do well are not always the fastest — they are the ones who can hold focus from the first section to the last without flagging.
- Creative writing that shows control. The Creative Composition is short but carefully read. Markers reward planning, vocabulary range, varied sentence rhythm, and a clear arc. Boys who start with “Once upon a time” are not the ones being offered places.
- Real curiosity, not rehearsed answers. The interview rewards boys who have actually thought about something — a book, an idea, a problem — and can speak about it in their own words. Rehearsed lines drop the temperature in seconds.
- Kindness alongside intelligence. The group activity is genuinely observed. CLS wants boys who lift others up in group settings, not boys who steamroller them. The school’s “Kind, Aware, Ready” framing is not marketing.
The six most common pitfalls
- Practising only on paper. The Stage 1 assessment is entirely online. A boy who has only practised paper tests will be slower on screen, will lose marks navigating the interface, and will not have built the muscle memory for online assessment. Practise on screen from spring of Year 5.
- Treating the Creative Composition as an afterthought. Many parents focus on Maths and English comprehension and underweight creative writing. CLS reads the Composition carefully. Drill STAR structure and In the Action openings from spring of Year 5.
- Rehearsing interview answers. CLS interviewers can spot a rehearsed answer in the first sentence. Drill the Out Loud Method — speak through your thinking, not your conclusions.
- Ignoring the group activity. Some parents do not realise there is a group activity at all. It is observed, and it matters. Practise group discussion at home: family dinner conversations, structured debate with siblings, anything that builds the habit of listening then contributing.
- Misreading the bursary process. CLS bursaries are transformational, but the application runs in parallel with admissions and has its own deadlines. Start the conversation before the November registration deadline if you need support.
- Reading too narrowly. Bright boys often read only one genre. CLS comprehension rewards boys who have read across genres — contemporary fiction, classic literature, age-appropriate non-fiction, quality newspapers.
The 12-month preparation pathway
A calm, well-paced 12 months for a Year 5 boy targeting CLS.
November to December (Year 5): Foundations. A diagnostic in English and Maths. Daily reading, 20–30 minutes, mixing genres. Begin a vocabulary book. Confirm Year 4 and Year 5 maths fluency.
January to March (Year 6): Building. Introduce online practice — Atom Learning’s own platform is a good starting point. Inference Ladder for comprehension. Column Method and LCM Method as default arithmetic. STAR structure introduced for creative writing — one short piece per fortnight.
April to June: Pace and accuracy. Online mocks every three to four weeks. Begin timed creative writing under exam conditions. Reading rises in difficulty. First interview practice — informal conversations about books and ideas.
July to August: Mastery. Two online mocks per month. Creative writing weekly. Side-by-Side Review every mock. A real summer holiday in there.
September to early November: Final run-in. Full online mocks at CLS pace. Interview practice intensifies — including the Out Loud Method on open questions. Register by early November.
Late November: Stage 1 week. Light maintenance only. No new content. Sleep tightens to 9.5 to 10 hours.
December to January: Interview run-in.After the late-November assessment, a short pause. Mid-December onwards: light interview preparation, one conversation a week. Christmas: a real break. Early January: two practice interviews, including a group discussion activity.
The final eight weeks
From early October to late November, your son is in the run-in.
Eight weeks out (early October). Three sessions a week. One full online mock per fortnight. Build in genuine break time.
Six weeks out (mid-October). Two online mocks across this fortnight. Half-term falls roughly here — plan two light sessions, then real downtime. Sleep schedule moving towards an exam-day pattern.
Four weeks out (late October). Two mocks per week, shorter sessions in between. Practise the Anchor Face technique.
Two weeks out (early November). One online mock, a confidence mock. Finish all heavy revision.
Assessment week (late November). No mocks. Light vocabulary review only, 15–20 minutes a day. Walk or check the route to CLS in advance. Two evenings before: early dinner, a film, early night. The night before: lay out the equipment. He sleeps. You read.
THE ANCHOR FACE TECHNIQUE Boys lose marks on online assessments not because they don’t know the answer, but because a tricky question early on sets the panic spiralling. When he meets a question he can’t do in 30 seconds, he marks it, breathes once, and moves on with his face deliberately neutral. The face affects the body. The body affects the next answer.
Note from Reena. In the final week, your job as a parent is not to add. It is to remove. Remove distractions. Remove screens after 8 pm. Remove the impulse to ask “Are you ready?” every five minutes. Your calm is the most important variable in your son’s exam-day performance.
Mock exam strategy for CLS
Mocks are not just a rehearsal. Used well, they are the most efficient piece of preparation.
When to start. Not in the first six months. Short-format online mocks from late spring of Year 5. Full-format online mocks from June of Year 5. Pace-pressure mocks from September of Year 6.
What a good CLS-format mock looks like. Online format, Atom-style multi-section pacing, with creative writing component included. Marked the same week with a written report.
How to read a mock report. The score is the least important. The breakdown of where marks were lost (by topic, by question type) is where the value sits. Track the trajectory, not the absolute score.
THE SIDE-BY-SIDE REVIEW METHOD After every mock, your son sits with a fresh page. On the left, the question he got wrong. On the right, in his own handwriting, is the correct working step-by-step. Five mocks done this way teach more than fifty done without review.
Our CLS mocks run several times across Year 5 and Year 6, calibrated to the November assessment.
Frequently asked questions
Is the online format harder than paper?
Not harder, but different. The pace is faster, the navigation matters, and boys who only practise on paper are slower. Build online practice in from spring of Year 5.
My son is bright but careless. Can he be ready?
Almost always, yes. "Bright but careless" usually translates as "has the ability but has never had the technique." Named techniques like Skip-and-Return, Inference Ladder, and 4-Step Elimination give a careless bright boy somewhere to put his attention.
How important is the creative writing piece?
More important than parents think. CLS reads it carefully. Drill STAR structure and varied openings from spring of Year 5.
What about the group activity?
It is observed and it counts. Practise group discussion at home. The skill is contributing without dominating.
Are bursaries genuinely available?
Yes. CLS commits all available bursary funds to means-tested awards, with support up to 100% of fees plus trips and extras. Start the application conversation before the November registration deadline.
How does CLS compare to St Paul's, KCS, or Westminster?
CLS sits between St Paul's (more academically intense, smaller intake) and KCS (more pastoral, both A Level and IB at Sixth Form). Westminster is more central and has just gone co-ed at 11+. All four serve different temperaments. Visit and decide which feels right for your son.
How do I know if my son has a realistic chance?
We know after one diagnostic and one trial class. Within two hours we can usually tell you whether CLS is realistic, ambitious, or beyond comfort.
No 11+ programme can guarantee an offer. Anyone who tells you otherwise is selling you something.
What preparation can deliver is this. By the time your son sits the CLS assessment in November, he will know the online format inside out. He will have named techniques for every question type. He will have written creative compositions under timed conditions multiple times. He will walk into the assessment calm. And by interview in January, he will have had real conversations with adults he doesn’t know, in his own words. Whether the offer comes is in his hands. But he will sit it as the best version of himself.
That is what twelve good months can do.
